The upcoming discussion will update you about the differences between transpiration and guttation. Transpiration: 1. Water is lost in the form of vapours. 2. It occurs through stomata's, lenticels and cuticle. 3. It occurs mostly during the day when temperature is comparatively higher. 4. It occurs through all aerial plant parts. 5. It takes place under dry conditions which do [...]
Let us make in-depth study of the period of stomatal opening and types of stomatal movement with diagram. The opening and closing of stomata is known as stomatal movement. When guard cells are turgid, stomata open and when flaccid, stomata close. The outer wall (convex) of guard cell is thin and inner wall (concave) is thick. Due to endosmosis, TP [...]
The following four points will highlight the four major factors affecting opening and closing of stomata. The four factors affecting opening and closing of stomata are: (1) Light (2) Water Content of Epidermal Cells (3) Temperature and (4) Mineral Elements. The aforementioned details pertain to the mechanism of opening and closing of photoactive stomata (i.e., stomata that open during day [...]
