What is cell?
INTRODUCTION
1. Cell is the basic unit of living things
ANIMAL CELLS
2. All living things are made up of one
or more cells.

QUESTIONS
3. The term ‘cell’ was first used by
Robert Hooke, a botanist. He observed
that cells in a sliced piece of cork and
the cells of a honeycomb alike.
4. You need a microscope to observe cells.
