A rapid loss of water in specialized cells in the sensitive plant Mimosa pudica causes __________.
A
seed germination
B
the plant to bend toward light
C
stomatal opening, initiating photosynthesis
D
stress that results in the production of PR proteins
E
leaves to droop
Verified step by step guidance1
Understand the context: Mimosa pudica is known for its rapid movement in response to touch or other stimuli, which is a defense mechanism.
Identify the specialized cells involved: These are the cells in the pulvinus, a joint-like structure at the base of the leaf or leaflet.
Recognize the mechanism: The rapid loss of water in these cells leads to a change in turgor pressure, causing the leaves to droop.
Consider the options: Seed germination, bending toward light, stomatal opening, and stress response are not directly related to the rapid loss of water in Mimosa pudica's specialized cells.
Conclude that the rapid loss of water in these cells results in the leaves drooping, which is a characteristic response of Mimosa pudica.
