Q.5.Assertion (A)The cell membrane is a dead part of the cell. Reason (R)Cell membrane regulates the movement of materials between the interior of the cell and the outer environment.

ᴀɴsᴡᴇʀ:-

Assertion is false reson is trueʕ•ᴥ•ʔ

ᴇxᴘʟᴀɴᴛɪᴏɴ:

Assertion is false because :-

Plasma Membrane is always living,no matter the cell is living or dead. It is composed of Lipids and proteins.

Reson is true because:-

The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Answer 2

The Assertion is true and the reason is false.

CELL WALL-

• A living outer layer that is present in cells as a protection of the cell content from the surrounding.
• The layer is a bilayer made of phosphate and lipid molecules.
• The layer is semi-permeable and facilitates the entry and exit of specific substances.
• The Cell membrane has vital functions in the cell such as -

1. Maintain the shape of the cell.

2. Act as a wall between cell organelles and the surrounding environment.

3. Transport of substances in and out of the cell.

4. Proteins embedded in the membrane acts as receptors.

5. Helps in cell mobility, exocytosis, and endocytosis of the substances across the membrane.

6. It facilitates the process of cell signaling.
