Answer A:
1. Spiral chloroplast:
This organelle help in photosynthesis, because it contain green pigment called chlorophyll in which water and carbon dioxide combine in the presences of sun light to prepare glucose.
2. Cell wall:
It is chemically composed of<span> an outer layer of pectin and an inner layer of cellulose. It provide rigidity and shape to spirogyra cell.</span>
Answer B:
The other parts which are not labelled include mucilage, cytoplasm, pyrenoids, cytoplasmic strand.
Answer C:

<span>Each chloroplast strand has several round bodies called 'pyrenoids', which are responsible for starch production.
</span>Function of mucilage:
Mucilage help in retaining water in cell.
the different particles would enter the root hair cell by osmosis.
<h3>what is osmosis ?</h3>
Osmosis can be the passive process where the molecules move from the region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane with out expenditure of external energy.
Gases and liquids are solvent undergo the process of osmosis; It can be Endosmosis where a substance in a hypotonic solution, the solvent molecules move inside the cell and the cell becomes turgid by a process of DE plasmolysis.
