11 Cards in this Set
- Front
- Back
Cell Wall
|
-found in some cells, including plants, algae, fungi, and nearly all prokaryotes (not animal cells)
-surrounds the cell membrane (allows water and gasses to pass through) -provides support and protection for the cell |
|
Nuclear Envelope
|
-Double membrane layer which surrounds nucleus
-thousands of pores allow material into and out of the nucleus |
|
Cytoskeleton
|
-network of protein filaments that helps the cell maintain shape and to move around.
|
|
Ribosome
|
-ribosomes are made of RNA and protein
-proteins are assembled (made) here. -proteins are produced following the specific code in DNA |
|
Endoplasmic Reticulum -Rough ER
|
-some proteins are modified
-components of the cell membrane are assembled -rough ER - ribosomes on the ER make proteins and these new proteins move into the ER where they may be chemically modified |
|
Smooth ER
|
-smooth ER - no ribosomes; contains specialized enzymes that perform specific tasks
|
|
Golgi Apparatus
|
-proteins produced by rough ER ribosomes move into these sac like structures
-enzymes attach carbohydrates and lipids to the proteins -these proteins are then sent to their final destination |
|
Lysosome
|
-filled with digestive enzymes
-break down cars, lipids, and proteins for use by cell |
|
Vacuole
|
- store materials like water, salts, proteins, and carbs for the cell
- reason plants are rigid -pants - single large vacuole filled with liquid -animals have many small vacuoles called vesicles |
|
Chloroplast
|
-plants only
-use energy from sun to make glucose (photosynthesis) -bound by a double membrane |
|
mitochondria
|
-break down glucose to make higher energy compounds
-bound by a double membrane |
