EVERYDAY SCIENCE

Detailed explanation-1: -The water eventually is released to the atmosphere as vapor via the plant’s stomata-tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration.

Detailed explanation-2: -Transpiration occurs when plants take up liquid water from the soil and release water vapor into the air from their leaves.

Detailed explanation-3: -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.

Detailed explanation-4: -Plant transpiration is generally an invisible process as the water from the exiting the leaves evaporates quickly. The temperature inside the bag will increase with heating from the sun. However, the water vapor will condense back into water as it comes in contact with the bag’s surface.

Detailed explanation-5: -Observation: We will notice small droplets of water inside the plastic bags that were tied around the branch with the leaves, while the other plastic bag does not have any droplets. This shows that water vapour is released by the leaves. Thus transpiration has occurred.
