Cell Membrane
|
Protective outer covering of all cells that regulates the interaction between the cell and the environment.
|
Cytoplasm
|
Constantly moving gel-like mixture inside the cell membrane that contains heredity material and is the location of most of a cell's life processes.
|
Cell Wall
|
Rigid structure that encloses, supports, and protects the cells of plants, algae, fungi, and most bacteria.
|
Organelle
|
Structure in the cytoplasm of a eukaryotic cell that can act as a storage site, process energy, move materials, or manufacture substances.
|
Nucleus
|
Organelle that controls all the activities of a cell and contains hereditary material made of proteins and DNA.
|
Nucleolus
|
Found within the nucleus of the cell and is the site of ribosome production.
|
Chloroplast
|
Green, chlorophyll-containing, plant-cell organelle that uses light energy to produce sugar from carbon dioxide and water.
|
Mitochondria
|
Cell organelle that breaks down food and releases energy.
|
Ribosome
|
Small cytoplasmic structure on which cells make their own proteins
|
Endoplasmic Reticulum
|
Cytoplasmic organelle that moves materials around in a cell and is made up of a complex series of folded membranes; can be rough or smooth.
|
Golgi Body
|
Organelles that package cellular materials and transport them within the cell or out of the cell.
|
Cytoskeleton
|
A network of fibers in the cytoplasm, gives cells structure and helps them maintain shape.
|
Central Vacuole
|
Makes up most of the cell's volume and stores water, waste products, food, and other cellular materials.
|
Vacuole
|
Found in animal cells, and are small and numerousl. They store water, waste products, food, and other cellular materials.
|
Lysosomes
|
Contain digestive chemicals that help break down food molecules, cell waste, and worn-out cell parts.
