Question

Which characteristic of sclerenchyma cells provides strength to the plant parts?

(a) Presence of cells with regular shape

(b) Presence of thin walls and dead cells

(c) Presence of large spaces between the cell

(d) Presence of thick walls and no internal space​

Answer 1

Answer:

(D) Presence of thick walls and no internal space

Explanation:

Because these cells are dead at maturity and lack cell content and have thick,lignified secondary walls which make them hard and rigid .

Answer 2

(d) Presence of thick walls and no internal space​ characteristic of sclerenchyma cells provides strength to the plant parts

Explanation:

Presence of cells with regular shape:

• The plant cells' uniform shape is due to rigid cell walls. In the plant call, cell walls are engineered to withstand water pressure.
• Cellulose is a structural carbohydrate found in plant cell walls. The plant cells' uniform shape is due to rigid cell walls.

Presence of thin walls and dead cells:

Based on the nature of the cell walls, it can be split into three types.

• The initial walls of parenchyma cells are thin, and they frequently stay alive after they mature.

• Collenchyma cells have thin main walls with subsequent thickening in some regions.

Presence of large spaces between the cell:

• Branched cells with extensive intercellular gaps make up the spongy layer in leaves. Aerenchyma is a term that is frequently used to describe parenchyma with extensive air spaces.

Presence of thick walls and no internal space​:

• The thickened lignified walls of sclerenchyma cells make them robust and waterproof. They're usually divided into two categories: support kinds and conducting forms.
• Sclerenchyma grows with the surrounding tissues and provides more long-term support than collenchyma, allowing the plant to preserve its established form.
