Question

Write three significant points about Sclerenchyma and parenchyma tissue

Answer 1

1)Parenchyma cells help in storage of foods, in gaseous exchange, and in photosynthesis.

2)Sclerenchyma cells provide mechanical support to the plant.

3)sclerenchyma also supports transportation of water and nutrients to the plants

4)They protect the plant from harsh weather conditions and harmful external factors.

Answer 2

Answer:

*Parenchyma cells have thin primary walls and usually remain alive after they become mature. Parenchyma forms the "filler" tissue in the soft parts of plants, and is usually present in cortex, pericycle, pith, and medullary rays in primary stem and root.

*Sclerenchyma cells have thick lignified secondary walls and often die when mature. Sclerenchyma provides the main structural support to a plant.
