DENDROLOGY

Detailed explanation-1: -Carbon dioxide is a gas found in the air; plants can take in this gas through tiny holes in their leaves. Once they have water and carbon dioxide, they can use energy from sunlight to make their food. The leftovers from making the plant food is another gas called oxygen.

Detailed explanation-2: -To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant’s leaves, flowers, branches, stems, and roots. Plants also require water to make their food.

Detailed explanation-3: -Carbon dioxide, water, and light are the ingredients plants need in order to make their food to grow. Carbon dioxide is a gas that we humans breathe out.

Detailed explanation-4: -During photosynthesis, carbon dioxide and water are converted into glucose and oxygen. Glucose is a large molecule with 6 carbon molecules (C6H12O6), therefore the smallest number of carbon dioxide (CO2) molecules required to make one molecule of glucose is 6!
