Question: What is the primary function of the cell membrane?
Answer: ✔✔ The cell membrane controls the movement of substances in and out of the cell,
maintaining the cell's internal environment.
Question: What are the basic units of life according to cell theory?
Answer: ✔✔ According to cell theory, the basic units of life are cells, which are the smallest
units that can perform all life processes.
Question: Which organelle is known as the "powerhouse" of the cell and why?
Answer: ✔✔ The mitochondrion is known as the "powerhouse" of the cell because it produces
ATP, the cell's main energy source, through cellular respiration.
Question: What is the role of ribosomes in the cell?
Answer: ✔✔ Ribosomes are responsible for protein synthesis, translating genetic information
from mRNA into proteins.

The rough ER has ribosomes and synthesizes proteins, while the smooth ER is involved in lipid
synthesis and detoxification processes.
Question: How do cells maintain homeostasis?
2
, Answer: ✔✔ Cells maintain homeostasis through mechanisms like regulating the internal
environment, managing waste removal, and responding to external changes to keep conditions
stable.
Question: What role do mitochondria play in cellular respiration?
Answer: ✔✔ Mitochondria are crucial for cellular respiration as they generate ATP through the
oxidation of nutrients, providing energy for various cellular functions.
Question: What is the function of the Golgi apparatus?
Answer: ✔✔ The Golgi apparatus modifies, sorts, and packages proteins and lipids for delivery
to different destinations inside or outside the cell.
Question: How does osmosis differ from diffusion?
Answer: ✔✔ Osmosis is the diffusion of water across a semi-permeable membrane, while
diffusion refers to the movement of solutes from an area of higher concentration to an area of
lower concentration.
Question: What is the significance of the cytoskeleton in a cell?
