Answer:

(A) To maintain balance of water and nutrients in the cell

Explanation:

According to the fluid mosaic model of the cell membrane to describe its structure proposed in 1972, the cell membrane possess components such as phospholipids, proteins and cholesterol. The phospholipid forms a bilayer in biological cell membranes.

The phospholipid bilayer is said to be AMPHIPATHIC i.e. they contain both hydrophobic (water-fearing) and hydrophilic (water-loving) regions. The phosphate head of the phospholipid is the hydrophilic region while the long fatty acid tails that face each other inwardly are the hydrophobic regions.

This amphipathic nature of the cell membrane is important to maintain the balance of water and nutrients in the cell because they control which substance can go in and out of the cell.

The cell membrane separates the intracellular environment from the extracellular environment outside of the cell. A phospholipid is composed of a phosphate group and a lipid. It is composed of a hydrophilic, polar phosphate head and two hydrophobic fatty acid tails.


The structure of the bilayer is such that the tails are shielded from contact with water, creating a selectively-permeable barrier which will be impermeable to most hydrophilic molecules.


So, the answer is A) To maintain balance of water and nutrients in the cell.

What are the reactions of the first stage of photosynthesis
wlad13 [49]

The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
