NEET BIOLOGY

Detailed explanation-1: -The leftovers from making the plant food is another gas called oxygen. This oxygen is released from the leaves into the air. Take a look at the picture below to see this system in action. This leftover oxygen is really important because humans and other animals need this oxygen to live which we breathe in from the air.

Detailed explanation-2: -Here is the super hero part. Through a process called photosynthesis, leaves pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree. But as a by-product of that chemical reaction oxygen is produced and released by the tree.

Detailed explanation-3: -Photosynthesis and respiration are the two essential processes that allow life to sustain on earth. In a way, they are a cycle-plants help humans breathe by providing us with oxygen, and humans help plants “breathe” by providing them with carbon dioxide.

Detailed explanation-4: -Simplified, we breathe in oxygen and carbon dioxide out, and plants do the opposite. We breathe in and out through our mouths but how do plants breathe? Plants also have mouths. The green parts of land plants are covered with tiny units called stomata, which is Greek for mouths.

Detailed explanation-5: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
