This question is incomplete; here is the complete question:

All of the following are examples of organic matter soil except

A. Decaying plants

B. Bacteria

C. Fungi

D. Water

The answer to this question is D. Water

Explanation:

Organic matter derives from living beings, due to this, organic matter is considered as a biological product. In this context, materials such as decaying plants are organic matter because they derive from living organisms and contain biological molecules (most contain carbon). This category does not apply to water, which is composed of hydrogen and oxygen and does not derive from living beings. Thus, the one that is not organic matter is water.

Function of cell wall:

The cell wall is the protective covering of the cells that are present in plants, fungi, bacteria and in case of Archean. Different cell walls are made of different chemicals in different organism.

Cell wall provide the mechanical support to the organism. The shape, size and integrity of the cell is maintained by the cell wall.

The cell wall of plants cell also provide turgidity to the plants. The cell wall of bacteria helps them to survive in extreme environmental conditions.

The process of diffusion, cell growth, structural maintenance, storage and communication functions are provided by the cell wall.
