Detailed explanation-1: -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’.

Detailed explanation-2: -Chlorophyll is a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis.

Detailed explanation-3: -Chlorophyll absorbs energy from sunlight which a plant uses to make food. chloroplast: a plastid that contains chlorophyll and is the site where photosynthesis and starch formation occur. photosynthesis: the formation of carbohydrates in the chlorophyll containing tissues of plants exposed to light.
