NEET BIOLOGY

Detailed explanation-1: -Such plants undergo CAM photosynthesis as they open up their stomata during night and take in CO2. Stomata remains close during the day time to prevent the loss of water by transpiration. They store the CO2 in their cells until the sun comes out and they can carry on with photosynthesis during the day time.

Detailed explanation-2: -Stomata are mouth-like cellular complexes at the epidermis that regulate gas transfer between plants and atmosphere. In leaves, they typically open during the day to favor CO2 diffusion when light is available for photosynthesis, and close at night to limit transpiration and save water.

Detailed explanation-3: -The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Normally stomata open when the light strikes the leaf in the morning and close during the night.

Detailed explanation-4: -stomata open during night and remain closed during the day time.

Detailed explanation-5: -Stomata open in response to light, including blue and red light (Shimazaki et al., 2007). Red light induces stomatal opening via photosynthesis in the mesophyll and guard cell chloroplasts (Mott et al., 2008; Suetsugu et al., 2014). In contrast, blue light as a signal induces stomatal opening.
