1. Why does a plant need to conduct water?
2. What is transpiration?
Answers
Answer:
Plants need water for photosynthesis. It requires sunlight, water, and carbon dioxide. Plants need water to absorb nutrients from the soil. Water enters a plant's stem and travels up to its leaves, which is where photosynthesis actually takes place.
Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.

2. What is transpiration?
Transpiration is a process that involves loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools the plant down when the weather is very hot, and water from the stem and roots moves upwards or is 'pulled' into the leaves.
