Name 5 cells plant and animal cells have in common
cell membrane, cytoplasm, nucleus, ribsomes and mitochondria
1 of 20
Name 3 cells that only plants and algae cells have
cell wall, permanent vacuole and chloroplasts
2 of 20
Why are bacteria and yeast cells different to animal and plant cells?
They have a different structure
3 of 20
What is the function of the nucleus?
Contains genetic material and controls the cell
4 of 20
What is the function of cytoplasm and what is it contolled by?
Where most chemical reactions happen. Controlled by enzymes
5 of 20
What is the function of the cell membrane?
Controlls the movement of substances in and out of the cell
6 of 20
What is the function of mitochondria?
Most energy is released by respitation here
7 of 20
What is the function of ribsomes?
Protein photosyntheses happens here
8 of 20
What does the cell wall do?
Streangthens the cell
9 of 20
What is the function of chloroplasts?
Contains chlorophyll, which absorbs light energy for photosynthesis
10 of 20
Whyat is the function of the permenant vacuole?
Filled with cell sap to keep the cell turgid
11 of 20
What are bacterium and yeast cells?
a single-celled organism
12 of 20
What is a structural similarity between bacterium and yeast cells?
they both have cytoplasm and a membrane surrounding the wall
13 of 20
What is a difference between bacterium and yeast cells?
Bacterium has no distinct nucleus, whereas yeast does
14 of 20
What is the function of a leaf cell?
It absorbs light energy for photosynthesis
15 of 20
How is a leaf cell adapted?
Packed with chloroplasts. Regular shaped, closely packed cells form a continuous layer for efficient absorption of sunlight
16 of 20
What is the function of a root hair cell?
Absorbs water and mineral ions from soil
17 of 20
What is the function of red blood cells?
Contains haemoglobin to carry oxygen to the cells
18 of 20
What is the process of diffusion in the gut. (Particles move, from and to)
Particles move:Digested food products From: Gut cavity To: Blood in capillary of villius
19 of 20
What is the process of diffusion in the lungs. (Particles move, from and to)
Particles from: oxygen To: Alveolar air space From: Blood circulating around the lungs
