Multicellular organisms Humans are multi-cellular animals. That means we are made of lots of cells, not just one cell. Cells work together but they do not do the same thing We have specialised cells which means that each cell has a certain structure to help complete a unique job in our body
Specialised animal cells Animals are more complex than plants and they have a greater variety of different cell types. The human body contains about 50 trillion cells and more than 200 different types of cells. Can you think of some different types of cells in your body? Specialised animal cells
