HORTICULTURE

Detailed explanation-1: -Plants are autotrophs, which means they produce their own food. 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-2: -The small pores present on leaves help plants take in carbon dioxide and give out oxygen during the process of photosynthesis. These pores are called stomata.

Detailed explanation-3: -Plants make their food in a process called photosynthesis.

Detailed explanation-4: -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’. The foods are called glucose and starch.

Detailed explanation-5: -Final answer: The part of the plant that takes in carbon dioxide from the air for photosynthesis is the stomata.
