Current Question (ID: 12430)

Question:

Cells having cellulose, hemicellulose and pectin deposits on the wall and shows its presence commonly in the petiole of leaf and growing green stems belong to

Options:

1. Sclerenchyma
2. Collenchyma
3. Aerenchyma
4. Parenchyma

Solution:

Collenchyma is a type of simple plant tissue that is characterized by cells with thickened cell walls containing cellulose, hemicellulose, and pectin deposits. These thickened cell walls provide structural support to the plant while still allowing for flexibility and elongation. Collenchyma cells are often found in the petiole (leaf stalk) of leaves and in growing green stems, where they help provide support during active growth. Collenchyma cells are living cells and can undergo limited expansion as the plant grows.
