Studying Cells Flashcards
What is the function of the nucleus? (2)
- Contains genetic material/DNA
- Controls cell activity
What is the function of the mitochondria? (2)
- Site of aerobic respiration
- ATP production
What is the function of the rough endoplasmic reticulum? (3)
- Encrusted in ribosomes
- Site of protein synthesis
- Transports and stores proteins within the cell
What is the function of the smooth endoplasmic reticulum? (1)
- Site of lipid synthesis
What is the function of the ribosomes? (1)
- Site of protein synthesis
What is the function of the golgi apparatus? (2)
- Sorts, modifies and packages proteins and triglycerides
- Produces vesicles
What is the function of lysosomes? (2)
- Contains digestive enzymes
- Digests worn out organelles
What is the function of the cell surface membrane? (3)
- Made of a phospholipid bilayer
- Controls what enters and leaves the cell / selectively permeable
- Can be folded to increase surface area
What is the function of chloroplasts? (2)
- Contains thylakoids, stacked into granum
- Site of photosynthesis
What is the cell wall in algae and plants made from?
Cellulose
What is the cell wall in bacteria made from?
Murein / Peptidoglycan
What is the cell wall in Fungi made from?
Chitin
What is the function of a capsule? (2)
- Protects cell from immune systems
- Aids bacteria sticking together
What is the function of plasmid? (2)
- Circular DNA
- Contains antibiotic resistance genes
What is the function of the cell wall? (2)
- Provides rigid shape / structure
- Stops osmotic lysis
