Answer 2

The correct labels in the figure are- (a)Cell wall, (b)Cell membrane, (c)DNA, (d)Heterocyst, (e)Mucilagenous sheath.

So, the correct choice of the asked question is Option (2)

Explanation:

A dividing bacteria

1. In the first figure, that is, a dividing bacteria, the labels of (a), (b) and (c) are cell wall, cell membrane and DNA respectively.

2. The cell wall that is present in the bacteria is made up of peptidoglycan which is also known as or called as murein.

3. The cell wall has the function to protect the bacteria cell from any kind of damage and mechanical stress due to environmental factors.

4. The cell membrane of the bacterial cell is made of mainly both phospholipids as well as proteins.

5. The function of cell membrane is to regulate the materials that are entering and leaving the cell.

6. The DNA possess the most important thing, that is, the genetic material.

Nostoc

1. In the diagram of Nostoc, the labels of (d) and (e) are heterocyst and mucilagenous sheath respectively.

2. Heterocyst are specialised cells. Its function is to serve as the place where the organisms are able to fix atmospheric nitrogen.

3. Mucilagenous cells helps in protecting and covering the cell from damage or several kinds of disruptions.
