GENERAL HISTOLOGY

Detailed explanation-1: -Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.

Detailed explanation-2: -Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell.

Detailed explanation-3: -Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars).

Detailed explanation-4: -The mitochondrion is the organelle responsible for producing usable energy for the cell, therefore the answer is a. Mitochondria are often referred to as the powerhouse of the cell because they are responsible for producing the bulk of the cell’s ATP via aerobic respiration.

Detailed explanation-5: -The machinery that the mitochondria use to convert energy is called the electron transport chain. Mitochondria convert chemical energy, in the form of a chemical called adenosine triphosphate or ATP for short. ATP is an energy currency that every cell in our body can use.
