BIOD 101 MODULE 1 – PORTAGE LEARNING EXAM
2026 (TEST BANK)
1. ⬛ True or False:
A hypotonic solution causes cells to shrink due to water loss.
CORRECT: False
Explanation: Hypotonic solutions cause water to enter cells, leading to swelling.
2. ,̀¸‘ Fill-in-the-Blank:
The structure that serves as the “distribution system” of the cell and modifies, packages, and
distributes proteins is the .
CORRECT: Golgi Apparatus
3. H
] Definition:
_
Define "osmosis."
CORRECT: Osmosis is the passive diffusion of water across a selectively permeable
membrane.
Explanation: It helps regulate cell volume and pressure.
4. ˛
C Short
*
Why are phospholipids considered amphipathic?
CORRECT: Because they have both hydrophilic heads and hydrophobic tails.
Explanation: This allows them to form bilayers in cell membranes.

Explanation: It’s typically strong and occurs between nonmetals.
8. C
* Short
˛
List two functions of proteins in cells.
CORRECT: Enzymes (catalysis), structural support, transport, signaling.
Explanation: Proteins are diverse in function due to varied structures.
9. ⬛ True or False:
Ribosomes are membrane-bound organelles.
CORRECT: False
Explanation: Ribosomes are not membrane-bound but are essential for protein synthesis.
