difference between parenchyma , collenchyma, and sclerenchyma on the basis of their cell wall.
Answers
Explanation:
Parenchyma has a thin cell wall of their cells, and are made up of cellulose. Whereas collenchyma cells have an uneven cell wall made up of pectin and hemicellulose. There is a hard and thick cell wall present of the sclerenchyma cells, which is made up of the lignin.
please mark my answer as brilliant.
Answer:
Parenchyma cells are the type of living plant cells, which are known for healing and repair mechanism, and food storage. Collenchyma cells are known for providing mechanical support to the plants, by protecting the delicate inner part of the plant. Sclerenchyma cells are the matured dead cells and are found in wooden part or hard stem of the plant.
Parenchyma is the most simple tissues made up of living cells and forming the thin layer called as primary cell wall of the plant. Parenchyma is taken from the Greek word “Parenchyma”, meaning ‘something poured in beside’. In plants, parenchyma cells are widely distributed all over and occur as continuous mass from the stems to roots, leaves, fruits.
Collenchyma cells are known as for providing the structural support to the cell. They are also living cells, having thick cell walls. The cell walls of the collenchyma cells are composed of the pectin, hemicellulose and cellulose and. The cells have a prominent nucleus with other organelles.
As we discussed that sclerenchyma is said as the dead tissues of the plants because it comprises of the hardwood. The secondary walls of the matured sclerenchyma cells are densely thick and contain lignin and hemicellulose. These types of cells are hard, non-growing and non-stretchable and are present in mature stems or bark.
