The outer covering in addition to cell membrane in plants is called as 

biology cell structure and micro-organisms plant and animal cell cell structure organisation of the organism

  1. Plasmalemma

  2. Capsule

  3. Cell wall

  4. Both A and B

Show answer
Correct Option: C
Explanation:

The cell wall is a tough, flexible and sometimes rigid layer that surrounds some cells e.g., plant cells. It surrounds the cell membrane and provides these cells with structural support and protection. In addition, the cell wall acts as a filtering mechanism. Animals do not have a cell wall.

The ................. allows high pressure to build inside of the plant cell without bursting.

biology cell structure and micro-organisms plant and animal cell cell structure organisation of the organism

  1. Cell wall

  2. Cytoplasm

  3. Nucleus

  4. Mitochondria

Show answer
Correct Option: A
Explanation:

The cell wall allows high pressure to build inside of the plant cell without bursting. The plant cell is able to accept large amounts of liquid through osmosis without bursting. This is due to the presence of cell wall which is absent in the animal cell.

A mature plant cell has

biology cell structure and micro-organisms plant and animal cell cell structure organisation of the organism

  1. Cell wall and protoplasm

  2. Protoplasm and vacuole

  3. Vacuole and cell wall

  4. Protoplasm, cell wall, and vacuole

Show answer
Correct Option: D
Explanation:
The protoplasm can be defined as a material which comprises of the living part of the cell including the cytoplasm, nucleus and other organelles. Plant cells are characterized by the presence of large vacuoles and cell wall, which are not seen in animal cells
So, the correct answer is 'Protoplasm, cell wall, and vacuole'.
