Final answer:
Option (b) is correct: the nucleus serves as the genetic control center, mitochondria are responsible for energy production, and ribosomes are the site of protein synthesis within cells.
Step-by-step explanation:
The correct match for cellular components in column A with the descriptions in column B from the options provided is option (b). Below is an explanation of the functions of each cellular component:
- Nucleus - This is the genetic control center of the cell, where the DNA is housed and replication and transcription occur. It is responsible for the regulation and coordination of activities such as growth, metabolism, and protein synthesis.
- Mitochondria - Referred to as the powerhouses or energy factories of the cell, mitochondria are accountable for energy production. They convert energy from nutrients into adenosine triphosphate (ATP), which the cell uses for various functions.
- Ribosomes - These are the sites of protein synthesis and they are found in all types of cells, including both prokaryotic and eukaryotic. Ribosomes read the genetic code from mRNA and link amino acids together to form proteins.
Therefore, option (b) Nucleus - Genetic control center, Mitochondria - Energy production, Ribosome - Site of protein synthesis is the accurate match.
