Answer 2

The answers are as follows:

1. Cell

• According to the cell theory, a cell is the smallest structural and functional unit of any living organism (except virus).

2. Robert Hooke

• Robert Hooke was the first to discover cells. He examined cork cells under a primitive microscope.

3. Cell Membrane

• Animal cells do not have a cell wall. The entry and exit of substances are regulated by the cell membrane.

4. Cytoplasm

• It is the main arena of cellular activities and reactions.

5. Nucleus

• It is analogous to the brain of the cell. It is also the protein factory of the cell and controls all the activities.

6. Organelles

• All the organelles function together as a unit to ensure the proper functioning of the cell.

7. Mitochondria

• It helps is cellular respiration. The inner membrane of mitochondria has infoldings.

8. Centriole

• It provides mechanical support to the cell and helps in cell division.

9. Endoplasmic Reticulum

• Along with Golgi bodies and lysosomes, it forms the endomembrane system of the cell.
