Answer & explanation
Correct answer: option 4
The correct answer is Option (4) – i - d, ii - a, iii - b, iv - c
i. Mitochondria - d. Energy generation
Mitochondria are known as the powerhouse of the cell because they produce energy in the form of adenosine triphosphate (ATP) through cellular respiration.
ii. Ribosomes - a. Protein synthesis
Ribosomes are responsible for protein synthesis in the cell. They are the site where mRNA is translated into proteins.
iii. Nucleus - b. Regulation of activity of a cell
The nucleus regulates the activity of the cell by controlling gene expression and storing the cell's genetic material (DNA).
iv. Lysosomes - c. Digestive system of a cell
Lysosomes are responsible for breaking down cellular waste and foreign particles through a process called autophagy. They contain enzymes that degrade cellular components and pathogens.
