Practice questions testing deep understanding of plant respiration, lenticels, and stomata.
Q1. It is traditionally advised not to sleep under a large tree during the night. Using your knowledge of plant respiration and photosynthesis, evaluate the biological validity of this advice.
Q2. The roots of a plant are completely submerged in waterlogged soil due to heavy flooding for over a week. The plant eventually dies. Explain how the waterlogged condition disrupted respiration and caused the plant's death.
Q3. Assertion (A): Stems of older, woody trees respire through small pores called lenticels. Reason (R): The bark of woody trees is covered with a thick, impermeable layer of cork, so stomata are no longer present or functional for gas exchange.
