8. Which organelle is known as the powerhouse of the cell?
a) Endoplasmic reticulum
b) Golgi apparatus
c) Mitochondria
d) Ribosome
Answer. c) Mitochondria is known as the power of the cell as it generates most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy generated by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
The cell is the smallest unit of the living organism.
Cell < Tissue < Organ < Organ System < Body

16. Which organelle is responsible for cellular respiration in Eukaryotic cells?
a) Endoplasmic reticulum
b) Golgi apparatus
c) Mitochondria
d) Ribosome
Answer. c) Mitochondria is known as the power of the cell as it generates most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy generated by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
