What is the most important property of life?
One of the most important characteristics of life is an organism's ability to reproduce. All living things reproduce sexually, with a partner, or asexually, by themselves.
What is the basic unit of life?
CellsCells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That's because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments.
What is life process?
The basic processes of life include organization, metabolism, responsiveness, movements, and reproduction. In humans, who represent the most complex form of life, there are additional requirements such as growth, differentiation, respiration, digestion, and excretion. All of these processes are interrelated.

What are the most basic organisms?
Organisms, in the most basic form, consist of highly organized structures that are made up of one or more cells. Even very simple, single-celled organisms are remarkably complex. Inside each cell, atoms make up molecules. These in turn make up cell components or organelles. Multicellular organisms, which may consist of millions of individual cells, have an advantage over single-celled organisms in that their cells can be specialized to perform specific functions.
What are some examples of organ systems that perform specific functions?
For example, organ systems such as the digestive or circulatory systems perform specific functions like carrying oxygen throughout the body, removing wastes, delivering nutrients to every cell, and cooling the body.
How do organisms grow?
Organisms grow (get larger) and develop (change over their lifespan) according to specific instructions coded for by their genes. These genes provide instructions that will direct cellular growth and development, ensuring that a species’ young (Figure 4) will grow up to exhibit many of the same characteristics as its parents.
How do cells function?
To function properly, cells require appropriate conditions such as proper temperature, pH, and concentrations of diverse chemicals. These conditions may, however, change from one moment to the next. Organisms are able to maintain internal conditions within a narrow range almost constantly, despite environmental changes, through a process called homeostasis or “steady state”—the ability of an organism to maintain constant internal conditions. For example, many organisms regulate their body temperature in a process known as thermoregulation. Organisms that live in cold climates, such as the polar bear (Figure 5), have body structures that help them withstand low temperatures and conserve body heat. In hot climates, organisms have methods (such as perspiration in humans or panting in dogs) that help them to shed excess body heat.
How do organisms respond to stimuli?
Organisms respond to diverse signals from the environment (stimuli). For example, plants can bend toward a source of light or respond to touch (Figure 1.3). Even tiny bacteria can move toward or away from chemicals (a process called chemotaxis) or light (phototaxis). Movement toward a stimulus is considered a positive response, while movement away from a stimulus is considered a negative response.
What is the characteristic of life?
Another important characteristic of life is reproduction. Reproduction is the ability of an organism to make more of the same type of organism. The new organisms that are made are called offspring. Although reproduction is not needed for the survival of an individual organism, it must occur for the continuation of the organism’s species.
What are the forms of life?
Humans, animals and plants are all forms of life.
What is a species?
A species consists of a group of organisms that can mate with each other and produce offspring that are able to reproduce. For example, there are many species of crocodiles including the American crocodile ( see image above ), the Australian freshwater crocodile, and the saltwater crocodile. American crocodiles reproduce only American crocodiles. In fact, without reproduction, the species would die out.
What happens to the offspring of an organism when it reproduces?
When reproduction occurs, organisms pass along genes containing DNA to an their offspring. These genes ensure that the offspring will belong to the same species and will have similar characteristics, such as size and shape.
What is the difference between living and nonliving things?
At times, nonliving things have one or more of the characteristics of life, but it is necessary to have all of the characteristics of life to be considered living. Things that have all of the characteristics of life are known as organisms.
How do organisms respond to stimuli?
Organisms respond to diverse stimuli. For example, plants can bend toward a source of light, climb on fences and walls, or respond to touch ( see image above ). Even tiny bacteria can move toward or away from chemicals (a process called chemotaxis) or light ( phototaxis ). Movement toward a stimulus is considered a positive response, while movement away from a stimulus is considered a negative response.
What are the characteristics of life?
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
What is the science that studies life?
Biology is the science that studies life, but what exactly is life? This may sound like a silly question with an obvious response, but it is not always easy to define life. For example, a branch of biology called virology studies viruses, which exhibit some of the characteristics of living entities but lack others.
How do organisms grow?
Organisms grow and develop following specific instructions coded for by their genes. These genes provide instructions that will direct cellular growth and development, ensuring that a species’ young (Figure 3) will grow up to exhibit many of the same characteristics as its parents.
Where do communities exist?
Communities exist within ecosystems, which exist in the biosphere.
Can an organism maintain internal conditions?
These conditions may, however, change from one moment to the next. Organisms are able to maintain internal conditions within a narrow range almost constantly, despite environmental changes, through homeostasis (literally, “steady state”)—the ability of an organism to maintain constant internal conditions.
Is each tree an organism?
For example, each tree in a forest is an organism. Single-celled prokaryotes and single-celled eukaryotes are also considered organisms and are typically referred to as microorganisms. All the individuals of a species living within a specific area are collectively called a population.
How many characteristics of life are there?
In order to categorize objects as either living or not living in a strict, logical, scientific manner, biologists have determined a basic set of 8 characteristics of life. For any object to be considered alive, it must have all eight of these properties.
What is a living thing?
Biology is the study of life. But what, exactly, does that mean? Although it may initially seem obvious whether something is alive or not, when approaching it scientifically, the definition and properties of life become far less obvious.
What is the ability to pass on genetic material from parent to offspring?
Heredity - Heredity is the ability to pass on genetic material (DNA) from parent to offspring. This can be in the form of phenotypic traits (the way a living thing looks on the outside) and genotypic traits (the actual genetic code that determines how something behaves and looks).
Is everything abiotic or biotic?
Everything can be classified as either biotic and abiotic . Abiotic things are nonliving, meaning that they are missing one or more of the 8 characteristics of life, while biotic things are living, which means they do have all 8 of these characteristics. These 8 characteristics are:
Sensitivity Or Response to Stimuli
- Organisms respond to diverse stimuli. For example, plants can bend toward a source of light, climb on fences and walls, or respond to touch (Figure 2). Even tiny bacteria can move toward or away from chemicals (a process called chemotaxis) or light (phototaxis). Movement toward a sti…
Reproduction
- Single-celled organisms reproduce by first duplicating their DNA, and then dividing it equally as the cell prepares to divide to form two new cells. Multicellular organisms often produce specialized reproductive germline cells that will form new individuals. When reproduction occurs, genes containing DNA are passed along to an organism’s offspring. These genes ensure that the offspr…
Adaptation
- All living organisms exhibit a “fit” to their environment. Biologists refer to this fit as adaptation, and it is a consequence of evolution by natural selection, which operates in every lineage of reproducing organisms. Examples of adaptations are diverse and unique, from heat-resistant Archaea that live in boiling hot springs to the tongue length of a nectar-feeding moth that matche…
Growth and Development
- Organisms grow and develop following specific instructions coded for by their genes. These genes provide instructions that will direct cellular growth and development, ensuring that a species’ young (Figure 3) will grow up to exhibit many of the same characteristics as its parents.
Regulation
- Even the smallest organisms are complex and require multiple regulatory mechanisms to coordinate internal functions, respond to stimuli, and cope with environmental stresses. Two examples of internal functions regulated in an organism are nutrient transport and blood flow. Organs (groups of tissues working together) perform specific functions, such as carrying oxygen …
Homeostasis
- In order to function properly, cells need to have appropriate conditions such as proper temperature, pH, and appropriate concentration of diverse chemicals. These conditions may, however, change from one moment to the next. Organisms are able to maintain internal conditions within a narrow range almost constantly, despite environmental changes, through ho…
Energy Processing
- All organisms use a source of energy for their metabolic activities. Some organisms capture energy from the sun and convert it into chemical energy in food (photosynthesis); others use chemical energy in molecules they take in as food (cellular respiration).
Evolution
- The diversity of life on Earth is a result of mutations, or random changes in hereditary material over time. These mutations allow the possibility for organisms to adapt to a changing environment. An organism that evolves characteristics fit for the environment will have greater reproductive success, subject to the forces of natural selection.
Cells / Order
Sensitivity Or Response to Stimuli
- Organisms respond to diverse signals from the environment (stimuli). For example, plants can bend toward a source of light or respond to touch (Figure 1.3). Even tiny bacteria can move toward or away from chemicals (a process called chemotaxis) or light (phototaxis). Movement toward a stimulus is considered a positive response, while movement away from a stimulus is co…
Reproduction
- Single-celled organisms reproduce by duplicating their DNA (deoxyribonucleic acid, the genetic material; see Figure 7) and then dividing it equally as the cell prepares to divide to form two new cells. Many multicellular organisms produce specialized reproductive cells that will form new individuals. When reproduction occurs, DNA is passed along to an organism’s offspring. Genes, …

Metabolism
- Metabolism means taking in and using energy. All organisms (such as the California condor shown in Figure 6) use a source of energy for their metabolic activities. Some organisms capture energy from the Sun and convert it into chemical energy in food; others use chemical energy from molecules they take in.

The 8 Properties of Life
- I :: Organization
All organisms are incredibly organized, consisting of various levels of organization at multiple orders of magnitudeof size and scalar resolution of reality. The level of organization exhibited by a living organism is so sophisticated as to exceed comprehension at this point. A single cell is beli… - II :: Sensitivity and Response to Stimuli
The second core property of life is that organisms respond to environmental stimulus.Plants can bend towards the light, even going so far as to climb up fences, walls, or trees towards a light source. If you touch the leaves of certain plants they will droop on contact, just like a human will …
VIII :: Evolution & Adaptation
- The last property of life is the belief that for something to be alive, it must be able to adapt and grow. In other words, it must be able to evolve. This is actually NASA’s definition of life for clarity in space exploration. That an organism must be a self-sustaining system and be capable of Darwinian evolutionfor it to be considered alive. Evolution is essentially an organisms adaptatio…
Defining Life with Properties of Life
- This list of properties of life is somewhat definitive. From looking into the world we can say with reasonable certainty that these criteria constitute some of the core properties of life, at least our definition of it, and defining what lifemeans. Yet that doesn’t mean that we fully understand everything about life and being alive, as if there are no revolutionary breakthroughs in our under…
