Question

ਕਿਸੇ ਨਾਰਮਲ ਬਾਲਗ਼ ਵਿਅਕਤੀ ਦੀ ਆਰਾਮ ਅਵਸਥਾ ਵਿੱਚ ਅੋਸਤ ਸਾਹ ਕਿਰਿਆ ਦਰ ਹੁੰਦੀ ਹੈ : *​

Answer 1

ANSWER

Leaves are adapted for photosynthesis and gaseous exchange. They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. Some of this water evaporates, and the water vapour can then escape from inside the leaf.
