Animal cells are surrounded by a thin membrane . They contain jelly-like cytoplasm which is made up of tiny working parts. One of these is the nucleus . The nucleus carries the 'recipe' which is used to tell the cell what to do, including telling it how to divide to make new cells. All plants, including grass, trees, herbs, garden plants and the vegetables we eat are made up of plant cells.
Plant cells are quite similar to animal cells.
They also have a membrane, a nucleus and jelly-like cytoplasm. But plants cells have some extra things. One is a stiff cell wall which stops the cell changing shape. Another is a group of green structures called chloroplasts . Chloroplasts use the energy from the Sun to make food.
