Chapter 7: Cell Structure And Function

Question 0

What are passive and active transport?

Answer 0

Passive transport is the movement of materials across the cell membrane without using cellular energy. Active transport is the movement of materials against a concentration difference. It requires energy.

Question 1

How are prokaryotic and eukaryotic cells different?

Answer 1

Prokaryotic cells don’t have a nuclei to sort DNA while eukaryotic cells do. Eukaryotic cells are more intense than prokaryotes and are either an animal or plant while prokaryotes are fungi.

Question 2

Be able to predict how mater will move in or out of a cell in hypotonic, isotonic, or hypertonic solution.

Answer 2

Hypertonic is when two solutions are next to each other and the solution moves out of the cell. Hypotonic is when the solution with the lesser solution solutes. Isotonic is when the solutions are both equal.
