Cell - Parts of a Cell
Terms
undefined, object
copy deck
- Nucleolus
- Ribosomes are made there.
- Cell Wall
- A rigid layer of nonliving material that surrounds the cells of plants. it's made of a tough, yet flexible material called cellulose.
- Chloroplast
- (plant cells only) Captures energy from sunlight and uses it to produce food for the cell. Gives plants their green color.
- Nucleus
-
Cell's control center. It directs all of the cell's actions. It also has a membrane.
*Brain - Lysosomes
-
(animal cells) Small round structures that contain chemicals that break down large food particles into smaller ones. Breaks down old cell parts and releases the substances so they can be used again.
*Clean-up Crew - Mitochondria
-
Rod-shaped, produces most of the energy that the cell needs to carry out it's functions.
*Powerhouse
(muscle cells and other active cells have large numbers of mitochondria) - Chromatin
- Strands in the nuclelous that contain genetic material.
- Ribosomes
-
Attached to the endoplasmic riticulum or float around freely in the cytoplasm. Makes proteins.
*Factories - Cell Membrane
-
All cells have cell membranes. Forms the ouside boundary that seperates the cell from it's environment. It controls what comes in/out of a cell.
*Gatekeeper - Golgi bodies
-
Recieve proteins and other material from the endoplasmic riticulam and sends them to other parts of the cell. Also releases materials outside the cell.
*Mailroom - Organelles
- Tiny cell structures, each having different functions.
- Cytoplasm
-
Region between the cell membrane and the nucleus. This fluid is always moving.
*Ocean
(clear, thick, gel-like fluid) - Endoplasmic Riticulum
-
Maze of passageways, carries proteins and other materials from one part of the cell to another.
*Highway - Vacuoles
-
Plant cells have them/Animal cells might not.
Stores food, water, waste prodcts, and other materials.
*Storage
