🧪 BIOD 101 MODULE 1 – PORTAGE LEARNING EXAM
(TEST BANK)
1. True or False:
A hypotonic solution causes cells to shrink due to water loss.
Answer: 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 ____________.
Answer: Golgi Apparatus
3. Definition:
Define "osmosis."
Answer: Osmosis is the passive diffusion of water across a selectively permeable membrane.
Explanation: It helps regulate cell volume and pressure.
4. Short
Why are phospholipids considered amphipathic?
Answer: Because they have both hydrophilic heads and hydrophobic tails.
Explanation: This allows them to form bilayers in cell membranes.
