Question

Common features between lenticels and hydrathodes are

• A. Both allow exchange of gases
• B. Always remain closed
• C. There is no regulation of their opening and closing
• D. They occur on the same organ of plant

Answer 1

The correct option is C There is no regulation of their opening and closing

Lenticels and hydathodes both lack guard cells and hence, their openings are not regulated. Hydathodes are openings at end of vascular supply to leaves and are involved in the process of guttation, which is loss of water in liquid form. Lenticels are lens shaped openings in big woody trunks of trees for gaseous exchange.
