What is a bacteria cell?
A bacterium is a single-celled organism. A bacterial cell has a different structure to an animal or plant cell.
10 of 16
Why is a bacterium cell different?
It has cytoplasm, a membrane and a surrounding cell wall, but the genetic material in a bacterial cell is not in a distinct nucleus.
11 of 16
What is a yeast cell?
Yeast is a single-celled organism.
12 of 16
What are the similarities of a yeast cell and a bacteria cell?
Like bacterial cells, yeast cells have cytoplasm and a membrane surrounded by a cell wall.
13 of 16
How is a yeast cell different to a bacteria cell?
Yeast cells have a nucleus
14 of 16
How does diffusion apply to cells?
Dissolved substances have to pass through the cell membrane to get into or out of a cell. Diffusion is one of the processes that allows this to happen.
15 of 16
When does diffusion occur?
Diffusion occurs when particles spread. They move from a region where they are in high concentration to a region where they are in low concentration. Diffusion happens when the particles are free to move.
