NEET BIOLOGY

Detailed explanation-1: -Plants do require oxygen to respire, the process in return gives out carbon dioxide. Unlike humans and animals, plants do not possess any specialized structures for exchange of gases, however, they do possess stomata (found in leaves) and lenticels (found in stems) actively involved in the gaseous exchange.

Detailed explanation-2: -The gas carbon dioxide is needed for photosynthesis to take place in plants and is also produced when plants respire. Oxygen is a product of photosynthesis-it is needed as a reactant during aerobic respiration within a plant.

Detailed explanation-3: -Plants do require oxygen for respiration which in return gives out carbon dioxide. Unlike animals, plants do not have any specialized structures for gaseous exchange but they have stomata (present in leaves) and lenticels (present in stems) which are involved in the exchange of gases.

Detailed explanation-4: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil.

Detailed explanation-5: -Photosynthesis is the process that plants use in the presence of sunlight to convert carbon dioxide taken in by their leaves and water taken in through the roots to produce oxygen and sugar (glucose). This process takes place in the chloroplast of the plant cell with the presence of the green pigment of chlorophyll.
