a) Plant cell wall is made up of cellulose

b) Plant cell wall is a non-living structure

c) Cell wall provides mechanical support to the cell

d) Cell was is semi-permeable

Answer: Plant cell wall is a non-living structure

Explanation:

The cell wall is the inanimate outermost covering of the cell and is made of cellulose and is permeable. Helps separate cell contents from the environment. It gives shape and protection to cells and is present only in plant cells and not in animal cells.

There are three layers in the cell wall of plants -

Primary cell wall - This layer is a generally flexible thin layer that forms during cell growth and is composed of cellulose, hemicellulose, and pectin.
Secondary cell wall - This is the thick layer that forms inside the primary cell wall after the cell grows and is found only in some cells, such as the conducting cells of the xylem. It can contain polymers such as cellulose, xylan, and lignin.
Middle Layer - This pectin-rich layer is the outermost layer. Forms interfaces between adjacent plant cells.
