Dear Student ,
Please find the answer to your asked query -
a) True. Potometer is an instrument used for demonstration of transpiration occurring from the lower surface of a leaf.
b) True
Trees absorbs a lot of water from the soil which is then released from the leaves as Water Vapours and gets back to the atmosphere. This then results in cloud formation and then rain.
e) True.
These plants whose stomata are sunken are known as Xerophytes. This is due to the result of adaptation changes to preserve water in areas where water is not available at huge quantities.
For rest of your question, please ask them in separate thread to get rapid assistance from our experts.
