Which of the following actions occurs in many plants when CO 2 concentrations are high?

When CO 2 concentrations are high, plants close their stomata to prevent further uptake of the gas, which can be toxic to the plant. This closure of the stomata leads to a loss of turgor pressure in the guard cells surrounding the stomata, causing them to close.
