NEET BIOLOGY

Detailed explanation-1: -Plants are able to carry out photosynthesis because they contain the organelle known as a mitochondrion. One important sugar that results from photosynthesis is cellulose. Light energy is changed to cell energy in stage 1 of photosynthesis. The green pigment that a absorbs light energy is chlorophyll.

Detailed explanation-2: -In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle-the chloroplast. Chloroplasts perform photosynthesis during the daylight hours.

Detailed explanation-3: -Photosynthesis occurs in the chloroplasts, whereas cellular respiration occurs in the mitochondria. Photosynthesis makes glucose and oxygen, which are then used as the starting products for cellular respiration.

Detailed explanation-4: -Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy.
