Question

In plant cells, cell wall is:

1. dynamic and live

2. rigid and non living

3. dynamic and non living

4. rigid and living ​

Answer 1

Answer: This may help you

Explanation:

In plant cells, cell wall is:

=> The cell wall is the outermost covering of plant cells. It is present outside the cell membrane and is tough, flexible and sometimes rigid in its texture. It is mainly composed of cellulose, long fibres of carbohydrates including hemicellulose, lignin, and pectin.

The dynamic nature of plant cell walls is an important feature that is lacking from most models. As cells grow and differentiate, new wall material is laid down near the plasma membrane and older wall material is pushed outward. This process has the potential to create a wall where the composition and architecture are not uniform across the wall.

Answer 2

In plant cells, the cell wall is rigid and non-living. (OPTION B)

PLANT CELL -

• The cell wall surrounds the plasma membrane made of cellulose.
• The cell wall provides protection and resistance against environmental stress.
• Cellulose is the long fibers of polymers called microfibrils therefore, the cell wall is dead.
• The cell wall is rigid provides structural support and shape to the cell organelles.
• The rigid and non-living cell wall helps the plant to stand upright.
