Structures represented in the illustration below are found in the lower epidermis of a plant leaf. The illustration at right shows the response to a certain
environmental condition.
Normal Conditions
Response to a condition
The response represented in the illustration would most likely be caused by-
O a reduced supply of oxygen
O long periods of rainfall
foy high concentrations of glucose
O little available water

The observation says that the illustration is guard cells the response represented in the illustration would most likely be caused by little available water.

They are produced in pairs with an opening among them that bureaucracy a stomatal pore.
The stomatal pores are biggest while water is free to be had and the protected cells are turgid and closed while water availability is significantly low and the protect cells end up flaccid.

What is the function of the guard cell?

Guard cells are some other kind of plant single-molecular fashions to look at early sign transduction and pressure tolerance mechanisms in plants. Guard cells are surrounded through stomatal pores and are placed in the leaf epidermis. Guard cells manipulate the inflow and efflux of CO2 and water from leaves, respectively.

Thus it is clear that The response represented in the illustration would most likely be caused by-little available water.
