2. How many kinds of cells are there?

There are two types of cells:

Cell wall, chloroplast and large vacuoles.

4. Name the parts of a cell that are present only in an animal cell.

Centrosome and cilia.

5. Name the parts of a cell that are present in both plant and animal cell.

Cell membrane, cytoplasm, endoplasmic reticulum, nucleus, lysosome, golgi apparatus, ribosomes, vacuoles and mitochondria.

6. Differentiate between a plant cell and an animal cell.

	Plant Cell	Animal Cell
Cell Shape	Square or rectangular	Irregular or round
Cell Wall	Present	Absent
Plastids	Present (like chloroplast)	Absent
Vacuole	Present (few/single, large, central)	small and numerous
Nucleus	Peripheral in location	Centrally located
Mitochondria	Present, but few in number	Present and numerous
Nutrition Mode	Autotrophic	Heterotrophic
Lysosomes	Very rarely present	Present
Centrosome	Absent	Present
Cilia	Absent	Present in most cases

7. Why do we stain plant or animal specimen before looking through a microscope?

We do so to easily different components of the cell.
