cells Flashcards
1
Q
prokaryotic
A
- single cell
- no nucleus or membrane bound organelles
2
Q
eukaryotic
A
- membrane bound organelles
- nucleus
- single or multi cellular
3
Q
nucleus
A
- Eukaryotic
- Plant or Animal Cells
- Stores DNA, controls gene expression, and regulates cell activities.
4
Q
smooth er
A
- Eukaryotic
- Plant or Animal Cells
- Lipid synthesis, detoxification, and calcium storage.
- No ribosomes on its surface
5
Q
rough er
A
- Eukaryotic
- Plant or Animal Cells
- Protein synthesis and folding.
- Studded with ribosomes that give it a “rough” appearance.
6
Q
cell membrane
A
- Prokaryotic and Eukaryotic
- Plant or Animal Cells
- Regulates the movement of substances in and out of the cell.
7
Q
peroxisome
A
- Eukaryotic
- Plant or Animal Cells
- Breaks down fatty acids and detoxifies harmful substances.
8
Q
lysosome
A
- Eukaryotic
- Mostly Animal Cells (Rare in Plants)
- Digests cellular waste and macromolecules.
9
Q
golgi apparatus
A
- Eukaryotic
- Plant or Animal Cells
- Modifies, sorts, and packages proteins and lipids for secretion.
10
Q
ribosome
A
- Prokaryotic and Eukaryotic
- Plant or Animal Cells
- Protein synthesis.
- Can be free in the cytoplasm or attached to the Rough ER.
11
Q
cell wall
A
- Prokaryotic or Eukaryotic
- Plant or Animal Cells
- Provides structure and protection.
12
Q
chloroplast
A
- Eukaryotic
- Plant Cells
- Photosynthesis – converts light energy to chemical energy.
- Contains chlorophyll, double membrane.
13
Q
plasmodesmata
A
- Eukaryotic
- Plant Cells
- Channels that allow communication and transport between plant cells.
- Bridges between plant cell walls.
14
Q
vacuole
A
- Eukaryotic
- Plant or Animal Cells
- Storage of nutrients, water, and waste products.
- Central vacuole in plants maintains turgor pressure.
15
Q
centrosome
A
- Eukaryotic
- Animal Cells
- Organizes microtubules and plays a role in cell division.
