Which among the following is incorrect about Sclerenchyma?a)These are ...
Explanation:
Sclerenchyma is a type of plant tissue that provides mechanical support to the plants. It is composed of cells that have thickened secondary cell walls, which make them rigid and provide strength to the plant.
Incorrect statement:
a) These are the living tissues responsible for stiffness in plants
The incorrect statement is option 'a' which states that sclerenchyma is living tissue responsible for stiffness in plants. In reality, sclerenchyma cells are dead at maturity. The cells undergo programmed cell death called apoptosis, which results in the deposition of lignin, a complex polymer, in the cell walls. This lignin deposition causes the cells to become non-living and provides rigidity and strength to the plant.
Correct statements:
b) The husk of a coconut is made of Sclerenchymatous tissue
The husk of a coconut is made up of sclerenchyma tissue. The thick and hard outer layer of the coconut husk is composed of sclerenchyma fibers, which provide protection to the inner seed.
c) They are of two kinds, namely, sclereids and fibers
Sclerenchyma tissue is classified into two types: sclereids and fibers. Sclereids are small, irregularly shaped cells with thickened cell walls. They provide mechanical strength and support to the plant. Fibers, on the other hand, are long and elongated cells with pointed ends. They are arranged in bundles and provide mechanical support to the plant.
d) Simple pits are present in thickened cell walls of sclerenchyma
Simple pits are indeed present in the thickened cell walls of sclerenchyma cells. These pits are areas of thinner cell wall where the secondary cell wall is absent or reduced. They allow for the movement of water and nutrients between adjacent cells.
In conclusion, option 'a' is incorrect because sclerenchyma is a dead tissue responsible for stiffness in plants, not a living tissue.
