Which of the following is a correct description of guard cell activity with regard to stoma?
When the guard cells become turgid with absorbed water, the stoma closes and CO2 cannot enter.
When the guard cells become flaccid from losing water, the stoma opens.
The activity of guard cells in opening and closing each stoma helps maintain a state of balance in the leaf that maximizes photosynthesis and minimizes transpiration.
Each stoma is controlled by a single guard cell, which absorbs water to open the stoma and loses water to close the stoma.
Which of the following is NOT one of the main functions of roots?
absorb nutrients
store food
carry out reproduction
anchor the plant
