What is transpiration? Mention its significance...​

Answer 1

Answer:

transpiration is the process of preventing water loss to plants.

Answer 2

• Transpiration is defined as the passage of water through a plant and the evaporation of water from aerial parts such as leaves, stems, and flowers.
• Although plants need water, only a small fraction of the water received by the roots is utilised for growth and metabolism.
• The remaining 97–99.5 percent is made up of perspiration and guttation.
• Most plants have more stomata (singular "stoma") on the undersides of their leaves.
• The stomata, which open and close the hole, are surrounded by guard cells and their stomatal auxiliary cells (referred to as the stomatal complex).
• Transpiration is a necessary "expense" associated with the opening of the stomata to allow carbon dioxide gas from the air to seep into the plant for photosynthesis.
