Question

Husk of coconut is made of _____ tissue.
A) Aerenchyma
B) Sclerenchyma
C) Parenchyma
D) Collenchyma

Answer 1

Hint: The cells are compact and non-stretchable and are typically located in plant bodies, like bark and mature roots, in nongrowing areas.

Complete Answer:
Plant cell is a multicellular eukaryotic cell that forms a plant. They have an established nucleus with specialized structural organelles that allow them to act in an ordered way as eukaryotic cells.

Now, let us find the solution from the options-
- Aerenchyma is a soft tissue that creates gaps or air tubes in some plant leaves, roots and stems, that enable gases to be transferred between the root and the shoot. Thus option A is not the correct option.
- Sclerenchyma is long, slender cells with a few or several pits with dense and lignified cell walls. These are usually observed in the fruit wall of nuts, the coconut husk, the legume seed coat, etc.
- In organs, parenchyma constitutes the main component and is tightly packed or has intercellular space and lives with the capacity for division. They execute photosynthesis, transportation, and secretion roles. Thus, option C is not only the correct option.
- Collenchyma in dicot plants is located in the hypodermis which provides the plant with mechanical assistance. Thus, option D is not the correct option.

Thus, the correct answer is option (B) Sclerenchyma.

Note: Sclerenchyma cells give support and protection to the tissues of other plants, particularly the tree trunks as well as fibres of large herbal trees, due to their thickened cell walls. Herbivory is prevented by the reinforced cell wall. Intake of the strong cell wall causes harm to larval stage insects' digestive tract, particularly in peach fruits.
