Nucleus
|
A large membrane bound structure that contains the cell's genetic material and controls the majority of the cell's activities. Control center of the cell. Contains DNA.
|
|
Cytoplasm
|
The area outside of the nucleus where specialized organelles are found.
|
|
Cell membrane
|
The thin, flexible barrier surrounding the cell.
|
|
Nuclear envelope
|
A double membrane that envelops the nucleus.
|
|
Nuclear pores
|
Area where information can flow in and out of the nucleus and membrane.
|
|
Nucleolus
|
Where the assembly of ribosomes begins.
|
|
Ribosomes
|
The site where proteins are synthesized. Small particles of RNA and proteins found throughout the cytoplasm either free- floating or attached to the endoplasmic reticulum.
|
|
Endoplasmic Reticulum
|
Transports materials through a cell; it is also where lipid components of the cell membrane are assembled along with proteins.
|
|
Rough Endoplasmic Reticulum
|
The portion of the ER that is involved in protein synthesis. Called "rough" ER because it has ribosomes along its surface.
|
|
Smooth Endoplasmic Reticulum
|
Does not have any ribosomes on it's surface.
|
|
Golgi Apparatus
|
An organelle that sorts, modifies and packages proteins and other material from the ER for storage in the cell or secretion out of the cell.
|
|
Lysosomes
|
Carry out intracellular digestion. Filled with enzymes that help to break down lipids, carbohydrates and proteins into small molecules that can be used by the rest of the cell. Break down unwanted material in the cell.
|
|
Vesicles
|
Saclike structures, found in most cells, which store materials.
|
|
Vacuole
|
A vesicle which contains mostly water.
|
|
Chloroplasts
|
The organelles that convert energy form the sun into energy that can be used by plant cells and some other organisms. The site of photosynthesis.
|
|
Cytoskeleton
|
A network of protein filaments that helps support the cell and helps with movement.
|
|
Microfilaments
|
Threadlike structures made of actin. They help support the cell and help the cell move.
|
|
Microtubules
|
Hollow structures made up of tubulins. They help maintain cell shape, assist in cell division, and help build flagella and cilia.
|
|
Centrioles
|
Found in the cytoplasm during cell division. They are not visible at other times of the cell cycle, but are present in a area of the cytoplasm called the centrosome. Composed of microtubules.
|
|
DNA
|
Provides the instructions for making proteins and other important molecules. Holds the hereditary genetic information of an organism.
|
|
Organelles
|
Structures in a cell with specific functions.
|
|
Mitochondria
|
Organelles that convert stored energy, from food, into energy that can be used by the cell. The site of cellular respiration.
