What are the characteristics of all living organisms?
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, adaptation, growth and development, homeostasis, energy processing, and evolution. When viewed together, these characteristics serve to define life.
How do living things change over their lifespan?
All living things increase in size and/ or change over their lifespan. For example, a human grows from a baby into an adult and goes through developmental processes such as puberty. Organisms grow and develop following specific instructions coded for by their genes (DNA). These genes provide instructions that will direct cellular growth and development, ensuring that a species’ young will grow up to exhibit many of the same characteristics as its parents, like the kittens seen in Figure 3.
How do single-celled organisms reproduce?
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 (reproductive) cells that will form new individuals. When reproduction occurs, DNA is passed from the organism to that organism’s offspring. DNA contains the instructions to produce all the physical traits for the organism. This means that because parents and offspring share DNA ensures that the offspring will belong to the same species and will have similar characteristics, such as size and shape.
What are the structures of an organism?
Organisms are highly organized, coordinated structures that consist 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 organelles and other cellular inclusions. In multicellular organisms, such as the toad seen in Figure 1, similar cells form tissues. Tissues, in turn, collaborate to create organs (body structures with a distinct function). Organs work together to form organ systems.
What is the source of energy for all organisms?
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 (such as grass and bacteria that can perform photosynthesis); others use chemical energy in molecules they take in as food (such as the condor seen in Figure 5).
What are some examples of internal functions?
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 throughout the body, removing wastes, delivering nutrients to every cell, and cooling the body.
Why does DNA contain instructions to produce all the physical traits for the organism?
This means that because parents and offspring share DNA ensures that the offspring will belong to the same species and will have similar characteristics, such as size and shape.

What is the life on Earth made of?
All life on Earth is carbon based, meaning the living things are composed of complex molecules that contain the element carbon. Carbon is an excellent starting material to make many different complex molecules because it can form four different bonds. This allows for a wide variety of molecules to create living things. Although carbon can form bonds with many different elements, there are six main elements that make up living things:
What are the characteristics of living organisms?
But, what does it mean to be alive? Living organisms have specific characteristics that distinguish them from non-living things. First, living things have a highly organized structure. There are many different parts working together, each with a specific job. Living organisms also respond to their environment. They are able to sense changes in stimuli and respond accordingly. For example, a cheetah might sense prey nearby and then take actions to stalk and kill it. Living organisms also must be able to reproduce. Living organisms may reproduce asexually, where they simply divide into two identical copies, or they can produce sexually where sperm and egg create new, genetically different offspring. Living organisms grow over their lifetime through different stages of development after being born. They also are able to adapt to different conditions to stay alive and maintain homeostasis, or an internal balance. For example, when humans get too cold, muscles contract and shivering occurs to generate heat. This keeps our body temperature in a specific range of homeostasis. Although many students assume breathing is necessary for life, this is not a characteristic of living things. Many bacteria are anaerobic, meaning they do not need oxygen to survive, but still are considered living things. Thus, although humans specifically must breathe to stay alive, this is not a quality of all living things.
What are the basic units of life?
The molecules, such as carbohydrates, proteins, lipids and nucleic acids, then work together to create the basic units of life, cells. All living things are made of cells. Cells work together to form tissues in multicellular organisms and tissues form organs. Organs work together in organ systems to perform functions for the organism. Some examples of organ systems in humans include, reproductive system, circulatory system, respiratory system, and excretory system.
How do cells work together?
These functions of molecules not only keep cells alive, but allow cells to work together. In large multicellular organisms like plants and animals, cells work together in groups called tissues. Different types of tissues assemble to create organs, and organs work together in organ systems to perform common functions. This keeps the entire organism alive. For example, there are many organ systems in humans. The circulatory system pumps blood all over the body to deliver oxygen and nutrients and remove metabolic waste. The excretory system removes the metabolic waste from the body. The reproductive system is responsible for reproducing new organisms. The respiratory system facilitates gas exchange, taking in oxygen and exhaling carbon dioxide. The table below explains the function of each of the body systems in humans.
What are the building blocks of a cell?
Carbohydrates are used inside cells mainly for quick energy, but also can be used in structure and cell signaling. Proteins are the building blocks of cells and carry out many important functions from transport to catalyzing chemical reactions to structure. Lipids are used for long term energy storage. Nucleic acids contain the genetic information of the cell and include molecules like DNA and RNA.
How many atoms are in the body?
The six atoms just mentioned make up more than 98% of the tissue (excluding the bones of the skeletal system) of most living organisms. There are four types of complex carbon-based molecules in all living organisms: proteins, carbohydrates, lipids, and nucleic acids. We will examine each of these in a bit more molecular detail in this lesson extension.

What is the subtle sense organ?
Subtle sense organs: By subtle sense organs we mean the subtle aspect of our 5 sense organs by which we are able to perceive the subtle realm.

Also the fragrance may only be experienced by one person and not by the others in the same room. This is explained in more detail. Also refer to our article on – What is sixth sense?
Why do we have nescience?
The word Nescience stems from the fact that we identify ourselves with our gross body, mind and intellect and not with our true nature which is the soul or the God principle within us . Nescience is the root cause of unhappiness. Man gets attached to money, his own house, family, city, country, etc.

How many atoms are needed to make a molecule?
It takes only two atoms to make a molecule. Quarks - For many years it was thought that the smallest building blocks were atoms, but now we know that is not true. Scientists have found even smaller building blocks than atoms. These subatomic particles have a funny name - quarks. There are many "flavors" of quarks.
What are the areas of the Earth that are defined by the plants and animals that live in that geographic region?
