Chapter 1: Cellular Function

, Question 1
The movement of water across a cellular membrane from an area of low
solute concentration to an area of high solute concentration is called:

A) Meiosis
B) Osmosis
C) Lysis
D) Mitosis

Correct Answer: B

Rationale:
Correct (B): Osmosis is the passive movement of water across a
semipermeable membrane from an area of lower solute concentration to an
area of higher solute concentration. This process equalizes concentration
gradients without energy expenditure.

Incorrect (A): Meiosis is a form of cell division that produces gametes
(sperm and ova) with half the chromosome number.
Incorrect (C): Lysis is the breakdown or destruction of a cell, often by
osmotic pressure or enzymatic action.
Incorrect (D): Mitosis is the process of cell division that produces two
identical daughter cells for growth and repair.

Study Tip: "Osmosis = water moves where solute is higher. Remember:
'Water follows the salt.'"

Question 2
Cells become specialized in their structure and function through the process
of:

A) Proliferation
B) Atrophy
C) Differentiation
D) Pinocytosis

Correct Answer: C

Rationale:
Correct (C): Differentiation is the process by which cells become
