transpiration

Describe transpiration and relate this process with the cell surface and stomatal opening and closing.

Transpiration is the process by which plants lose water vapor to the atmosphere through small pores called stomata that are located primarily on the leaves, although some are also present on stems and flowers. This loss of water vapor helps maintain a transpiration pull that facilitates the movement of water and dissolved minerals from the … Read more

Why is transpiration called a necessary evil? What is the composition of translocating fluid?

Transpiration is called a necessary evil because, although it leads to the loss of water from the plant, it is essential for the uptake of minerals and water through the roots and for cooling the plant. The composition of the translocating fluid, which flows through the phloem, primarily consists of water, dissolved sugars (mainly sucrose), … Read more
