Question number: 102

» Plant Physiology » Transport in Plants » Transpiration-Opening and Closing of Stomata

MCQ▾

Question

Which one of the following describes a possible reason for the opening and closing of the guard cells?

Choices

Choice (4) Response

a.

Stomata open in daylight because starch is changed to osmotically active substances which increase the turgidity of the guard cells.

b.

Stomata close in darkness because the starch produced in daylight by photosynthesis; it is changed in to sugars and translocated from the guard cells.

c.

Stomata open in daylight because guard cells have chloroplast osmotic pressure arises.

d.

Stomata open in daylight because photosynthesis occurs in the guard cells producing sugar resulting in higher osmotic pressure.
