Correct answer and explanation

Correct answer: Transpiration

Explanation: āœ… Correct Answer: B) Transpiration šŸ“š Explanation: Transpiration occurs primarily through small openings on the leaf surface called stomata and serves to cool the plant and pump water and minerals from the roots. It creates a "transpirational pull" that allows water to travel upwards against gravity in tall trees. Nearly 99% of the water absorbed by plant roots is eventually lost through this process.
