How the structure and function of cells are linked?
The contents of the cell, or the structures of the cell, allow the cell to be "specialized." Together with the cell's proteins, they allow the cell to do specific things. They allow a cell to act like a neuron or a bone cell or a skin cell.
What is the structure of a cell?
A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
Where are eukaryotic cells found?
The eukaryotic cells types are generally found in animals, plants, algae, and fungi. For the purpose of this article, the primary focus will be the structure and histology of the animal cell. The major differences between animal and plant cells will be explored as well. As previously stated, the fundamental components of a cell are its organelles.
What are the components of a cell?
As previously stated, the fundamental components of a cell are its organelles. These organelles are made up of varying combinations of atoms and molecules. The organelles drive different functions of the cell from metabolism, to energy production and subsequently to replication.
How do cells grow and replicate?
In order for cells to grow and replicate, they must produce the necessary building blocks to achieve this feat. Additionally, some cells – like the β-cells of the pancreas – produce protein based hormones to help maintain homeostasis . This process is achieved by ribosomes. Ribosomes are complex ribonucleic acid based molecules (i.e. ribosomal-ribonucleic acid; r-RNA) that are responsible for translating coded sequences of the messenger-RNA (m-RNA) to proteins. They are made up of a small and a large subunit which coordinate with each other to translate the m-RNA strand. Some ribosomes are membrane bound, while others float freely in the cytoplasm. While free ribosomes synthesize proteins that are used within the cell, the proteins synthesized by bound ribosomes are meant to be exported.
What is the smallest cell in an organism?
The cell is the smallest functional unit within a living organism, which can function independently. It is made up of several types of organelles that allow the cell to function and reproduce. There are two general classes of cells that exist: the self-sustaining simple cells known as prokaryotic (bacteria and archaea) and the more complex dependent cells known as eukaryotic. The eukaryotic cells types are generally found in animals, plants, algae, and fungi. For the purpose of this article, the primary focus will be the structure and histology of the animal cell. The major differences between animal and plant cells will be explored as well.
What is the function of the plasma membrane?
The plasma membrane is the outermost layer of the cell. The main function of the plasma membrane is to protect the cell from its environment. It is often referred to as a fluid mosaic phospholipid bilayer that is hydrophilic externally and internally, but hydrophobic at its core. The hydrophilic property arises from the charged phosphate molecule that forms the head of the phospholipid, and the hydrophobic nature is from the two lipid tails which forms the core. This feature allows the selective permeability of the membrane. For instance, particles that are hydrophilic (e.g. ions) are not able to pass through the hydrophobic core, and those that are hydrophobic (e.g. fats) are repelled from the outer surface. As a result, the cell is able to isolate its internal environment from the external environment.
How does the cell move substances?
The controlled movement of substance is done by protein channels and carrier proteins anchored in the plasma membrane that selectively or generally allow particular particles to enter and leave the cell.
Which type of cell has ribosomes bound to its surface, stores proteins, and is the extension of the?

Animals, plants, and fungi are all eukaryotic Cells, which are large complex organisms. It consists of membrane-bound organelles.
Eukaryotic cells classification
Animals, plants, fungi, and protists are the four types of eukaryotes. Protists are eukaryotic organisms that do not include animals, plants, or fungi; this group includes protozoa, slime moulds, and some algae. Animals and plants are multicellular, whereas protists and fungi are usually unicellular.
Eukaryotic cells organelles structure and function
In cell biology, an organelle is a specialized subunit within a cell that has a specific function, and is usually separately enclosed within its own lipid bilayer. Organelles are identified by microscopy, and can also be purified by cell fractionation.

What are eukaryotic cells?
By definition, eukaryotic cells are cells that contain a membrane-bound nucleus, a structural feature that is not present in bacterial or archaeal cells. In addition to the nucleus, eukaryotic cells are characterized by numerous membrane-bound organelles such as the endoplasmic reticulum, Golgi apparatus, ...
What is the membrane of an eukaryotic cell?
Like bacteria and archaea, eukaryotic cells have a plasma membrane, a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment. The plasma membrane controls the passage of organic molecules, ions, water, and oxygen into and out of the cell.
How many centrioles are in a centrosome?
Figure 8. The centrosome consists of two centrioles that lie at right angles to each other. Each centriole is a cylinder made up of nine triplets of microtubules. Nontubulin proteins (indicated by the green lines) hold the microtubule triplets together.
Why is the mitochondria called the energy factory?
Mitochondria (singular = mitochondrion) are often called the “powerhouses” or “energy factories” of a cell because they are the primary site of metabolic respiration in eukaryotes. Depending on the species and the type of mitochondria found in those cells, the respiratory pathways may be anaerobic or aerobic.
What is the cytoplasm?
The cytoplasm. The cytoplasm refers to the entire region of a cell between the plasma membrane and the nuclear envelope. It is composed of organelles suspended in the gel-like cytosol, the cytoskeleton, and various chemicals (see figure below).
Which organelle is responsible for photosynthesis?
Chloroplasts are plant cell organelles that carry out photosynthesis. Like the mitochondria, chloro plasts have their own DNA and ribosomes, but chloroplasts have an entirely different function.
Which organelle pulls chromosomes to opposite ends of the cell?
The centrosome (the organelle where all microtubules originate in animal and yeast) replicates itself before a cell divides, and the centrioles appear to have some role in pulling the duplicated chromosomes to opposite ends of the dividing cell. However, the exact function of the centrioles in cell division remains unclear, as cells that have had their centrosome removed can still divide, and plant cells, which lack centrosomes, are capable of cell division.
What is an eukaryotic cell?
What is a Eukaryotic Cell? Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organisms. Protozoa, fungi, plants, and animals all have eukaryotic cells. They are classified under the kingdom Eukaryota.
