Question

Cuticle is secreted by

• A. Epidermis
• B. Endodermis
• C. Both A and B
• D. Hypodermis

Answer 1

The correct option is A Epidermis

• Epidermis forms the outer protective covering of primary plant body. The epidermal cells secrete cutin, which is a hydrophobic substance and prevents water loss. The cutin forms a covering outside the epidermal cells in all plants parts except root.
• The innermost layer of cortex forms endodermis, which has compactly arranged barrel shaped cells. The primary thin walled endodermis shows suberin deposition in the form of bands or strips that run around the radial and end walls of the cells called Casparian strips.
• Hypodermis refers to 5-7 layers of cortical cells present just beneath the epidermis.

Hence the correct option is A.
