Question

Differentiate between parenchyma sclerenchyma collenchyma and arenchyma

Answer 1

Parenchyma, collenchyama, and sclerenchyma are three types of simple, permanent tissues, collectively called ground tissue in plants. Simple tissues are made up of a single cell type, which forms a homogenous, uniform cell mass in the body of the plant. Parenchyma is the most abundant type of cells in simple tissues. They are isodiametric cells containing thin cell walls. Parenchyma cells are found in all organs of the plant, seeds, fruits, flowers, leaves, stems and roots. Collenchyma cells consist of unevenly thick cell walls. They contain vacuolated protoplasts and are absent in monocots. Sclerenchyma cells are dead cells at their maturity, containing the thickest cell walls. They are specialized cells found in mature parts of the plant body. The main difference between parenchyma collenchyma and sclerenchyma is that parenchyma cells are involved in photosynthesis, storage, and secretion, while collenchyma cells are involved in support and transportation of nutrients and sclerenchyma cells are involved in the support, protection, and transportation of water and nutrients.
