a) Matthias Schleiden and Theodor Schwann

b) Robert Hooke

c) Antony Van Leeuwenhoek

d) Aristotle


Answer. a) Matthias Schleiden and Theodor Schwann ( 1838 1839)


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


9. Which organelle is known as the protein factory in eukaryotic cells?

a) Endoplasmic reticulum

b) Golgi apparatus

c) Mitochondria

d) Ribosome


Answer. d) Ribosome is the site of protein production in eukaryotic cells. 

Ribosome is known as the factory of protein.


10. Which organelle is responsible for the storage of lipids or synthesis of lipids in eukaryotic cells?

a) Endoplasmic reticulum

b) Golgi apparatus

c) Mitochondria

d) Ribosome


Answer. a) Endoplasmic reticulum is responsible for the storage of lipids or synthesis of lipids in eukaryotic cells.

The Endoplasmic Reticulum also transports nutrients from one part of the cell to the other


11. Which organelle is responsible for protein synthesis in eukaryotic cells?

a) Endoplasmic reticulum

b) Golgi apparatus

c) Mitochondria

d) Ribosome


Answer. d) Ribosome is responsible for protein synthesis in eukaryotic cells. 


12. Which organelle is known as the traffic police of cells?

a) Endoplasmic reticulum

b) Golgi apparatus

c) Mitochondria

d) Ribosome


Answer. b) The Golgi apparatus is known as the traffic police of cells

The primary function of the Golgi apparatus is the modification of protein.

b) Lipid Synthesis

c) Detoxification

d) Protein modification


Answer. a) Protein synthesis


14. Which of the following is a primary function of the Golgi apparatus in eukaryotic cells?

a) Protein synthesis

b) Lipid Synthesis

c) Detoxification

d) Protein modification


Answer. d) Protein modification


15. Which of the following is a primary function of the Endoplasmic reticulum in eukaryotic cells?

a) Protein synthesis

b) Lipid Synthesis

c) Detoxification

d) Protein modification


Answer. b) Lipid Synthesis


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).


17. Which organelle is known as the Suicide bag of Cells?

a) Endoplasmic reticulum

b) Lysosome

c) Mitochondria

d) Ribosome


Answer. b) Lysosome is known as the suicide bag of cells.

The primary function of Lysosome is to serve the digestive system of cells as it has digestive enzymes. It helps in cell division.
