What do animal and plant cells both have?
- Nucleus
- Cytoplasm
- Cell membrane
What does only a plant cell have?
- Cell wall
- Vacuole
- Chloroplasts
What does a nucleus do?
Controls the activity of the cell
What does the cytoplasm do?
This is where chemical reactions take place
What does a cell membrane do?
Controls what goes in and out of the cell
What does the cell wall do?
Strengthens the cell
What does the vacuole store?
Cell sap
What do chloroplasts do?
Absorb light energy to make food
What are properties of animal and plant cells?
- Multicellular
- Has a defined nucleus
- Contains mitochondria
What are properties of a fungus?
- Unicellular
- Has a nucleus
- Has a cell wall (chitin)
- Contains mitochondria
What are properties of bacteria?
- Unicellular
- No defined nucleus
- Slime caps
- Cell wall (murein (not cellulose))
- No mitochondria
What does a fungi cell have?
- Cell wall
- Nucleus
- Vacuole
- Cytoplasm
- Mitochondria
- Cell membrane
What does a bacteria cell have?
- Ribosomes
- Cell wall
- Capsule
- Cell membrane
- Loop of DNA
- Cytoplasm
What is mitochondria?
Where aerobic respiration takes place
What is a specialised cell?
A differentiated cell (it has developed into a specific type of cell so it has a specific job) e.g. red blood cell, sperm cell
What are the adaptations of a red blood cell?
- High surface area (biconcaved disc)
2. No nucleus = more space for haemoglobin
What do the different parts of a leaf do?
Waxy layer: reduced evotranspiration
Palisade layer: lots of chloroplasts
Spongy mesophyll: short diffusion pathway
Guard cell: opens and closes to produce stomata opening
Stomata: can open and close to allow gas exchange
