Detailed explanation-1: -The “powerhouses” of the cell, mitochondria are oval-shaped organelles found in most eukaryotic cells. As the site of cellular respiration, mitochondria serve to transform molecules such as glucose into an energy molecule known as ATP (adenosine triphosphate).

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: -The nucleus is the largest and most significant living organelle of the cell. All cell activities of the cell are regulated by the nucleus. Hence it is called brain or control centre of the cell.

Detailed explanation-4: -Cytoskeleton. Within the cytoplasm there is network of protein fibers known as the cytoskeleton. This structure is responsible for both cell movement and stability.
