What do the arms of brain cells look like?
Their arms look spider-like.
These cells measure between 0.01 and 0.05mm. What cells are they?
Animal cells.
These cells measure around 0.1mm in size.
Plant cells.
What shape do liver cells have?
Liver cells have a hexagonal shape.
Give at least two features of a plant cell.
They are: bigger than animal cells, have a regular shape, have a rigid cell wall around the membrane, and have chloroplasts.
What are chloroplasts?
Chloroplasts contain a green substance called chlorophyll, which is used to carry out photosynthesis.
How does a rigid cell wall help the plant?
The rigid cell wall helps to strengthen the shape and structure of the plant.
Give at least two features of a cell that both plant and animal cells have.
Examples include: cell membrane, nucleus, nucleolus, ribosomes, vacuole, mitochondria.
Give at least two examples of what plant cells have that animals don't.
Two from: chloroplasts, cell wall and plasmodesmata.
Give at least two examples of what animal cells have that plants don't.
Two from: Centrioles, lysosomes and centrosomes.
