Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why do plants need air (carbon dioxide) to grow?
A
Plants use carbon dioxide to make food
B
Plants use carbon dioxide to transport food to different parts of the plants
C
Plants use carbon dioxide to keep firm
D
Plants use carbon dioxide to reproduce
Explanation: 

Detailed explanation-1: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. 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.

Detailed explanation-2: -Plants take in – or ‘fix’ – carbon dioxide from the atmosphere during photosynthesis. Some of the carbon is used for plant growth, and some of it is used in respiration, where the plant breaks down sugars to get energy.

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: -The two primary reasons plants need is air to photosynthesize (make food) and to breathe. Plants need to breathe for the same reason people and animals must breathe – they need oxygen to convert food into energy. The relationship between air and indoor plants is crucial to keeping your plants looking their best.

Detailed explanation-5: -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.
