Question

the substance present in the wall of sclerenchyma?
​

Answer 1

Answer:

sclereids and nucleus are present

Answer 2

Sclerenchyma Wall  in Plant

Explanation:

1. The sclerenchyma is guide in contrast to collenchyma, mature cells of this tissue are typically lifeless and feature thick partitions containing lignin. Their size, shape, and structure range substantially.
2. Sclerenchyma cells are robust, thick cells that offer maximum of the assist in a plant. they're recognized to have extraordinarily thick cellular walls and do now not take part in the various other sports of the growing plant, inclusive of photosynthesis, due to the fact their attention is precisely on support and structure.
3. They've a massive relevant vacuole and a dense cytoplasm. The parenchyma tissue is placed within the soft components of the plant inclusive of cortex and pith. Sclerenchyma ,The cells of the sclerenchyma tissue are useless. The cell wall could be very thick because of the deposition of lignin.
4. Fibers and sclereids are the forms of sclerenchyma cells Their cellular partitions consist of cellulose, hemicellulose, and lignin.
5. Parenchyma was found in seventeenth century by means of the biologist named Robert Hooke. Sclerenchyma call observed by the biologist named Mettenius.
6. Lignin is a polymer that shape key structural substances.it is important within the formation of cell walls, in particular in bark and wooden because they lend rigidity and do not rot easily.
7. Lignin is a completely unique hydrocarbon comprising eight-20% of the secondary cellular wall of terrestrial plants.
