LIFE SCIENCE

Detailed explanation-1: -The leaves of the plant first prepare Glucose by photosynthesis, then glucose is converted to starch.

Detailed explanation-2: -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-3: -In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose. In mitochondria, through the process of cellular respiration breaks down sugar into energy that plant cells can use to live and grow.

Detailed explanation-4: -Glucose is the first form of food substance produced during photosynthesis.
