DENDROLOGY

Detailed explanation-1: -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’.

Detailed explanation-2: -They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.

Detailed explanation-3: -Photosynthesis takes place in the part of a plant cell called a chloroplast. Chloroplasts are found in the cells of leaves. Chloroplasts use chlorophyll to store the food they have created using sunlight, water, and carbon dioxide.

Detailed explanation-4: -Photosynthesis is the process by which food is prepared in the leaves using carbon dioxide and water in the presence of sunlight. The leaves have chlorophyll, a green pigment which help them in absorbing sunlight.
