Cell Transport Biology

Particle of movement from an area of higher concentration to an area of lower concentration.

• Active transport

• Passive transport

Which illustration of transport across the membrane requires energy?

• A

• B

• C

• D

Facilitated diffusion is the movement of materials into and out of the cell

• with the use of energy

• with the use of proteins but no energy

• by moving water

• by using ATP

In this situation, where the solute is illustrated by red dots, predict if will WATER move into or out of the cell, and how that will affect the cell.

• Water will move into the cell and the cell will expand.

• Water will move into the cell and the cell will shrink.

• Water will move out of the cell and the cell will expand.

• Water will move out of the cell and the cell will shrink.

The two broad categories of cell transport are ...........

(select all correct answers)

• passive transport

• road transport

• food transport

• active transport

When particles move from areas of high concentration to areas less concentrated, this has taken place.

• diffusion

• mitosis

• endocytosis

• photosynthesis

Why is diffusion and osmosis important to cells?

• It allows them to take in materials without using energy.

• It allows them to reproduce.

• It allows them to absorb sunlight.

• It allows cells to use all energy.

What does selectively-permeable mean?

• The cell controls what passes in and out of the cell

• Nothing gets through

• The cell lets only large substances through

Where is there a low concentration of dye?

• at the bottom of cup

• in the color

• at the top of cup 

• no concenteraion gradient

You are alone on an island in the middle of the Atlantic Ocean. You are hot and thirsty, so you want to drink water from the ocean. You think about biology class and you decide:

• to drink the ocean water because the extra salt will quench your thirst.

• not to drink the ocean water because the extra salt will cause you to dehydrate.

• to drink the ocean water because your cells will burn more fat due to the salt intake.

• not to drink the ocean water because the extra salt will cause your cells to burst.
