Question

What are the factors affecting stomatal movement?

Answer 1

Stomata:

1. They are specialized holes or openings which are found in the epidermis of plant cells, are essential for gas exchange during the process of photosynthesis.
2. In the epidermis of leaves, stalks, and other portions of all green plants, stomata are present.
3. According to how turgid the guard cells are, stomata open and close.
4. Numerous environmental factors, including light, temperature, humidity, water accessibility, and CO₂ concentration have an impact on stomatal motility. Growth hormones, organic acids, K⁺, Cl^-, and H⁺ ions are examples of internal or endogenous components.
5. Normally, stomata open when light reaches the leaf and close at night.
