Plant Cell

A plant cell has the following structure.

There are three major differences between the plant and animal cell that are worth noting.

Cellulose cell wall is made from dense fibres and forms an extra layer of protection which maintains the cell's shape and prevents it from bursting when it takes on more water.

The large vacuole stores sap and is especially important in osmosis since it stores water in the cell.

And the chloroplasts, found in the cells of the green parts of the plant, are where photosynthesis takes place and are green because they are pigmented with chlorophyll which involved in absorbing light for photosynthesis.

Palisade Leaf Cell

The top layer of cells in a leaf are called the pallisade leaf cells. They are specially adapted to make the most of the light conditions they recieve. So they have many more chloroplasts than other plant cells, to produce as much glucose as possible.

Palisade cells are also more block shaped (like the one on this page is) so that many of them can be packed into the top layer of the leaf.
