Detailed explanation-1: -Mitochondria (singular, mitochondrion) are often called the powerhouses or energy factories of the cell. Their job is to make a steady supply of adenosine triphosphate (ATP), the cell’s main energy-carrying molecule.
Detailed explanation-2: -Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Detailed explanation-3: -(A) The mitochondrion converts energy from chemical fuels. (B) The chloroplast converts energy from sunlight. Inputs are light green, products are blue, and the path of electron flow is indicated by red arrows.
Detailed explanation-4: -Plant cells require both chloroplasts and mitochondria since they carry out both cell respiration and photosynthesis. Chloroplasts and mitochondria are cell organelles of a plant cell. Chloroplast is the site of photosynthesis in plant cells. It converts light energy(sunlight) into chemical energy.
