NEET BIOLOGY

Detailed explanation-1: -Green plants use carbon-dioxide, water and light to build starch that is plant’s food. It is well known that plants can not live without water and light.

Detailed explanation-2: -If carbon dioxide is completely removed from a plant’s environment, we would expect the plant to stop producing high-energy sugars altogether. CO2 is necessary for the plant to perform photosynthesis, meaning without CO2 the plant has no way to obtain energy-it will likely die in this scenario.

Detailed explanation-3: -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-4: -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-5: -Carbon dioxide, along with water, is one of the key ingredients that plants need to perform photosynthesis. With falling carbon dioxide levels, less photosynthesis will occur and some types of plant may die out altogether.
