Current Question (ID: 12508)

Question:

Epiblema of roots is equivalent to

Options:

1. Pericycle
2. Endodermis
3. Epidermis
4. Stele

Solution:

Epiblema, also known as the root cap, is the outermost layer of the root tip in plants. It is equivalent to the epidermis, which is the outermost layer of cells that covers the entire surface of roots, stems, leaves, and other plant organs. The epidermis of roots usually includes specialized structures such as root hairs for absorption of water and nutrients, and it protects the inner tissues of the root from mechanical damage, pathogens, and water loss. Option 1 is incorrect as the pericycle is a layer of cells located just inside the endodermis in the root, and it is not equivalent to the epiblema. Option 2 is incorrect as the endodermis is a distinct layer of cells located just inside the cortex of the root, and it is not equivalent to the epiblema. Option 4 is incorrect as the stele refers to the central core of vascular tissues in roots and stems, and it is not equivalent to the epiblema.
