Stomata- specialized cells that contract and expand to open or close pores for gas exchange. Stomata can adjust to temperature, staying when temperatures are hot and dry to prevent gas and water loss.

CLOSED.

Explanation:

Stomata are found in epidermal layers in green aerial parts of plants, especially leaves. They occur mainly on the lower surface of dicotyledonous leaves, although on monocotyledonous, they are found on both surfaces. Intercellular air spaces found throughout the leaf are linked to stomata.

Stomata permits plant uptake of carbon dioxide, which is a necessity for photosynthetic processes. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration.

Therefore, it can be said that Stomata adjust temperature, staying closed when temperatures are hot and dry.
