The formation of air tubes in submerged roots is an adaptation to __________.
A
water deficit
B
salt stress
C
heat stress
D
cold stress
E
oxygen deprivation
Verified step by step guidance1
Understand the context: Submerged roots are often found in environments where the soil is waterlogged, leading to low oxygen availability.
Identify the problem: In waterlogged conditions, the roots may experience oxygen deprivation because water fills the spaces in the soil that would normally contain air.
Recognize the adaptation: The formation of air tubes, also known as aerenchyma, is a structural adaptation that allows plants to transport oxygen from the air to the submerged parts of the plant.
Connect the adaptation to the stress: Aerenchyma helps alleviate oxygen deprivation by facilitating the movement of oxygen to the roots, which is crucial for cellular respiration and survival in anaerobic conditions.
Conclude the reasoning: Therefore, the formation of air tubes in submerged roots is an adaptation specifically to address oxygen deprivation, not water deficit, salt stress, heat stress, or cold stress.
