Which of the following is true of stomata?

Question

Quizplus · Accepted Answer

Stomata are small pores found on the surface of leaves and stems of plants. They open to allow gas exchange between the plant and the environment but they also facilitate water loss, so they close to prevent excessive transpiration. Therefore, option C is correct. Option A is incorrect because stomata do not open to increase water absorption - that is the role of root hairs. Option B is also incorrect because stomata are not the same as pores; they have specialized guard cells that regulate their opening and closing. Option D is incorrect because not all land plants have stomata - for example, liverworts lack stomata.
