NEET BIOLOGY

Detailed explanation-1: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-2: -Plants need three main ingredients to make their food: water, carbon dioxide and sunlight. Plants take up the water that they need from the soil through their roots. Carbon dioxide is a gas found in the air; plants can take in this gas through tiny holes in their leaves.

Detailed explanation-3: -During photosynthesis, plants take in carbon dioxide, water, and light, and turn them into sugar and oxygen. Sugar is then used by the plants for food. Oxygen is breathed out into the atmosphere. Plant cells have a green pigment called chlorophyll in their cells.

Detailed explanation-4: -Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata. (One of these holes is called a stoma. The plural is stomata.

Detailed explanation-5: -Photosynthesis, respiration and transpiration are the three major functions that drive plant growth and development (Figure 24). All three are essential to a plant’s survival.
