However, in the same way that atoms are the basic unit when you study matter, cells are the basic unit for biology and organisms. In larger organisms, the main purpose of a cell is to organize. Cells hold a variety of pieces and each cell type has a different purpose. By dividing responsibilities among different groups of cells, it is easier for an organism to survive and grow.

The cell wall also bonds with other cell walls to form the structure of the plant. Chlorophyll (plant) The green pigment in the leaves and stems of plants that is necessary for the production of plant food by photosynthesis. Chloroplast (plant) An elongated or disc-shaped organelle containing chlorophyll.

The centriole is the dense center of the centrosome (plant cells do not have centrioles). Vacuole (animal) Fluid-filled, membrane-surrounded cavities inside a cell. The vacuole fills with food being digested and waste material that is on its way out of the cell. Vacuole (plant) A large, membrane-bound space within a plant cell that is filled with fluid.

Cell organelle. Definition. noun, plural: cell organelles. A membrane-bound compartment or structure in a cell that performs a special function. Supplement. A eukaryotic cell contains many organelles, for example, the nucleus, endoplasmic reticulum, golgi apparatus, mitochondria, and chloroplast (plastid).

Proteins needed inside the nucleus are transported in through the nuclear pores. The nucleolus is usually visible as a dark spot in the nucleus, and is the location of ribosome formation. Ribosomes are where RNA is translated into protein. This process is called protein synthesis. Protein synthesis is very important to cells, therefore large numbers of ribosomes are found in cells. Ribosomes float freely in the cytoplasm, and are also bound to the endoplasmic reticulum (ER).

Plant cells are easier to identify because they have a protective structure called a cell wall made of cellulose. Plants have the wall; animals do not. Plants also have organelles such as the green chloroplast or large, water-filled vacuoles. Chloroplasts are the key structure in the process of photosynthesis.

Microtubules function in cell division and serve as a temporary scaffolding for other organelles. Actin filaments are thin threads that function in cell division and cell motility. Intermediate filaments are between the size of the microtubules and the actin filaments.eeze-fracturing is able to split the bilayer.

Cells Vocabulary List & Definitions Term Definition Tissue The mass of like cells in an animal or plant body, esp. as they form a specific organ. Organ In a plant or animal, a specialized structure that performs a particular function, such as the heart. Organelle A specialized subunit within a cell that has a specific function, and is usually separately enclosed within its own membrane.

There are smaller pieces that make up cells such as macromolecules and organelles. A protein is an example of a macromolecule while a mitochondrion is an example of an organelle. Cells can also connect to form larger structures.

Mitochondria are a part of tissue cells that consists of an outer and an inner membrane. The mitochondria are the main energy source of the cell, in fact, they are often called the power plants of the body because this is where energy (ATP) is created.
