Question

. Assertion: The cell membrane is an active part of the cell.It regulates the movement of
materia's between the ordered interior of the all and the outer environment.
Reason: in plant cells,a cell wall composed mainly of cellulose is located outside the cell
membrane. The presence of the cell wall enables the cells of plants, fungi and bacteria to
exist in hypotonic media without bursing :
a. A b. B C. C d. D​

Answer 1

Answer:

All living cells contain a cell membrane, the semipermeable structure that surrounds the cell. ... This flexible ability is important because it allows the cell to survive in differing environments, such as when immersed in water over long periods of time

Answer 2

Both Reason and assertion are valid but are not related to each other.

• Cell membranes are also called plasma membranes. This is the outermost layer of animal cells.
• By selectively allowing certain substances into the cell, the membrane acts as a selectively permeable membrane.
• Lipids and proteins make up this semipermeable membrane.
• A plant's outermost covering is the cell wall. Located outside the cell membrane, it is tough, flexible, and sometimes rigid in texture.
• The main components of fiber includes cellulose, hemicellulose, lignin, and pectin, which are all long carbohydrates.
• Molecules of small size are able to pass without any discomfort through it.
