NEET BIOLOGY

Detailed explanation-1: -Animals and plants are connected to each other by the oxygen-carbon dioxide cycle. Plants need the carbon dioxide from animals to live and animals must have the oxygen from plants to survive.

Detailed explanation-2: -Most living things need oxygen to survive. Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.

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: -Almost all living things, including humans, need oxygen to survive. Both plants and animals take in oxygen from their surroundings to release energy.

Detailed explanation-5: -Oxygen (O) is responsible for cellular respiration in plants. This element plays a critical role in photosynthesis and is both stored for energy and released as a byproduct.
