TYPES OF CELLS (cellular specialisation)

Here you can watch this video about the different kinds of cells we can find in animals. I hope you enjoy it!

THE CELL

The cell

All living things are made of cells. A cell is the smallest unit of life. It is a living thing because it performs the three vital functions: nutrition, interaction and reproduction.

Parts of the cell

Animal cell:

These parts are in both animal and plant cells. Plant cells usually are bigger and have a regular shape, animal cells can be many different shapes.

Cytoplasm: it is inside the cell. It is a viscous liquid and the organelles are in it.

The nucleus: contains the material necessary to reproduce the cell and to control its activities. It is surrounded by a membrane.

The cell membrane: it is the covering around the cell. It takes part in the interaction function.

Organelles: control various functions.

Plant cell:

A part from these, plants have got two more parts.

The cell wall: it is a rigid structure that surrounds the cell membrane and protects the cell.

Chloroplasts: are green organelles that get the light and produce nutrients. Chloroplasts contains chlorophyl.
