- temperature
- light
- soil moisture
- atmospheric humidity
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Stomata are minute specialised pores generallypresent on leaf epidermis. Light is very important as most of the stomata open during day time.opening of stomata occurs in red ligh(660 nm) followed by blue light (445 nm) and nooccurs in green light.

Concepts Used:
Osmosis
Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane.
There are three different types of solutions:
- Isotonic Solution is one that has the same concentration of solutes both inside and outside the cell.
- Hypertonic solution is one that has a higher solute concentration outside the cell than inside.
- Hypotonic solution is one that has a higher solute concentration inside the cell than outside.
