What is the main source of water for a plant during photosynthesis?
Answer and explanation
Correct answer: Water absorbed by roots from soil
Water used in photosynthesis is mainly absorbed from the soil by root hairs. After absorption, it moves upward through the xylem, helped by root pressure, cohesion and transpiration pull, and reaches the leaves where photosynthesis occurs. The water is a raw material in glucose formation. Thus option A is correct; plants do not normally obtain their main supply directly from air or manufacture it in flowers or stems.
