Cells and their functions
Humans are multi-cellular animals. That means we are made of lots of cells, not just one cell. The cells in many multi-cellular animals and plants arespecialised, so that they can share out the processes of life. They work together like a team to support the different processes in an organism.
You should be able to work out special features of a cell from a drawing, if you are told what the cell can do. The tables below show examples of some specialised animal and plant cells, with their functions and special features.

To reach female cell, and join with it
