Perception of blue light in plants causes
inhibition of cell elongation and stimulation of stomatal opening.
stimulation of cell elongation and inhibition of stomatal opening.
inhibition of stomatal opening.
inhibition of cell elongation.
Answers (1)
Perception of blue light in plants can indeed lead to the inhibition of cell elongation and the stimulation of stomatal opening.
Plants have photoreceptor proteins called phototropins that are sensitive to blue light. When these photoreceptors absorb blue light, they trigger various physiological responses in plants. One of the effects is the inhibition of cell elongation in shoots, which helps regulate plant growth and development. This response is particularly important for phototropism, which is the directional growth of plants in response to light.
Additionally, blue light also plays a role in regulating stomatal opening and closing. Stomata are tiny pores on the surface of leaves that allow for gas exchange, including the intake of carbon dioxide for photosynthesis and the release of oxygen. When plants perceive blue light, it can stimulate the opening of stomata, leading to increased gas exchange and improved photosynthesis. This response is important for optimizing water use efficiency and controlling plant water balance.
Overall, the perception of blue light by plants triggers specific responses that help regulate growth, development, and physiological processes such as cell elongation and stomatal opening.
Hence, the correct answer is option 1.
