Question 1
What is the primary function of the cell membrane?
Explanation
The cell membrane regulates the movement of substances in and out of the cell through selective permeability.
Question 2
What role do mitochondria play in the cell?
Explanation
Mitochondria are responsible for producing ATP through oxidative phosphorylation, essential for cellular respiration.
Question 3
How does the cytoplasm contribute to cellular processes?
Explanation
The cytoplasm provides a medium for metabolic reactions and supports organelle movement.
Question 4
What misconception about cells is addressed in the source material?
Explanation
A common misconception is that all cells have the same structure and function, whereas different cell types are tailored for specific roles.
Question 5
What function is associated with the endoplasmic reticulum?
Explanation
The endoplasmic reticulum is involved in protein and lipid synthesis, with functions varying between rough and smooth ER.
Question 6
Which cellular organelle is involved in apoptosis?
Explanation
Mitochondria play a role in apoptosis, as they are involved in various metabolic functions and energy production.
Question 7
Gene therapy primarily targets which cellular component?
Explanation
Gene therapy aims to correct defective genes within the nucleus, highlighting its role in treating genetic disorders.
Question 8
Which of the following organelles is primarily responsible for the generation of ATP through cellular respiration?
Explanation
Mitochondria are known as the 'powerhouses' of the cell because they generate ATP through the process of oxidative phosphorylation, which is essential for cellular energy supply.
