Current Question (ID: 12511)

Question:

In dicot stem hypodermis is made up of __________ cells while general cortex is made up of __________.

Options:

1. collencyma, sclerenchyma
2. collencyma, parenchyma
3. parenchyma, sclerenchyma
4. parenchyma, collencyma

Solution:

Collenchyma cells are elongated cells with thickened cell walls, and they provide structural support to young stems and leaves. They are typically found in a few layers just below the epidermis, forming the hypodermis in dicot stems. The collenchyma cells are alive at maturity and are capable of limited cell division. Parenchyma cells are the most common type of plant cells, and they have thin cell walls and large central vacuoles. They perform a variety of functions in the plant, including storage, photosynthesis, and support. In dicot stems, the general cortex is made up of parenchyma cells, which store nutrients and water, and provide structural support to the stem.
