NEET BIOLOGY

Detailed explanation-1: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-2: -There are four main parts to the water cycle: Evaporation, Convection, Precipitation and Collection. Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapour or steam. The water vapour or steam leaves the river, lake or ocean and goes into the air.

Detailed explanation-3: -Photosynthesis produces water as a byproduct. During photosynthesis, plants take carbon dioxide ( C O 2 ), and water ( H 2 O ) from the air and soil. In the plant cell, carbon dioxide is reduced, which results in the gain of electrons, whereas water is oxidized, which results in the loss of electrons.

Detailed explanation-4: -The most well-known examples are plants, as all but a very few parasitic or mycoheterotrophic species contain chlorophyll and produce their own food. Algae are the other dominant group of eukaryotic photosynthetic organisms.
