DENDROLOGY

Detailed explanation-1: -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. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Detailed explanation-2: -The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas. After the sugar is produced, it is then broken down by the mitochondria into energy that can be used for growth and repair.

Detailed explanation-3: -During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.

Detailed explanation-4: -During photosynthesis, energy from sunlight is harvested and used to drive the synthesis of glucose from CO2 and H2O. By converting the energy of sunlight to a usable form of potential chemical energy, photosynthesis is the ultimate source of metabolic energy for all biological systems.

Detailed explanation-5: -Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch.
