Which feature do plant and algal cells have which help them to strengthen their cells?
They have a cell wall, which is made of cellulose.
2 of 10
What is the function of the chloroplasts in plants and and algal cells?
They absorb light energy to make food (carry out photosynthesis)
3 of 10
What is found inside the permanent vacuole of plants and algal cells?
Cell sap.
4 of 10
What is the difference between a plant and algae?
Algae is made up of single celled organisms (algal cells). Plants are multicellular (have lots of specialised plant cells working together).

What is important about genetic information in a bacterial cell?
It is not inside a distinct nucleus.
6 of 10
How do dissolved substances move in and out of cells?
Through the cell membrane, by diffusion.
7 of 10
Define diffusion.
Diffusion is the spreading of particles of a gas or of any substance in a solution from a region of higher concentration, to a region of lower concentration.
8 of 10
What will effect the rate of diffusion?
The size of the concentration gradient (differences in concentration of the particles on each side of the membrane). The higher the gradient, the faster diffusion is.
