Refer to page 94 and 95 of your Textbook.

Cells

All living things are made up of cells. Cells are the basic unit of living things.


Animal and plant cells have different structures.

The structures we will be look at will be:

  • cytoplasm
  • cell membrane
  • nucleus
  • cell wall
  • chloroplast
  • vacuole

Functions

It is where all chemical reactions take place.

It controls substances going in and out of the cell.

It controls all the activities of the cell including reproduction.

It stores water and other nutrients.

It protects and give plant cells a regular shape.
