Biology - Cells and simple transport

HideShow resource information
What are all living things made up of?
Cells.
1 of 20
What 5 parts does an animal cell contain?
Nucleus, cytoplasm, cell membrane, mitochondria and ribosomes.
2 of 20
What 3 extra parts do plant cells have that animal cells don't?
Cell wall, chylroplasts and a permenant vacuole
3 of 20
What is the function of the nucleus?
Countains genetic information which controls activity of the cell.
4 of 20
What is the function of the cytoplasm?
Most chemical processes take place here, controlled by enzymes.
5 of 20
What is the function of the cell membrane?
Contains the movement of substances in and out the cell.
6 of 20
What is the function of the mitochondria?
Most energy is released by respiration here.
7 of 20
What is the function of the ribosomes?
Protein synthesis happens here.
8 of 20
What is the function of the cell wall?
Strengthens the cell.
9 of 20
What is the function of the chlorplasts?
Contain chlorphyll, which absorbs light energy for photosynthesis.
10 of 20
What is the function of the vacuole?
Filled with cell sap to help keep the cell turgid.
11 of 20
What 3 parts does a bacteria cell contain?
Cell membrane, cytoplasm and cell wall.
12 of 20
What is another single celled organism?
Yeast.
13 of 20
What one extra part does a yeast cell contain?
A nucleus.
14 of 20
Name four specialised cells?
Leaf cell, root hair cell, sperm cell and red blood cell.
15 of 20
How is the leaf cell specialised?
Packed with chloroplasts so it can absorb light energy for photosynthesis.
16 of 20
How is the root hair cell specialised?
Large surface area so it can absorb water and mineral ions from the soil.
17 of 20
How is the sperm cell specialised?
Tail moves sperm around so it can fertilise an egg.
18 of 20
How is the red blood cell specialised?
They have no nucleus so the whole nucleus can be filled with ocygen to carry to cells.
19 of 20
When does diffusion occur?
Whe particles spread, moving from one region of high concentration to another of low concentartion. Particles must be free to move.
