Quizziz Review on Cellular Transport

Passive Transport is the movement of particles across the membrane from an area of [ ___ ] to an area of [ ___ ]

• high to low

• low to high

• low to low

• high to high

Where is there a low concentration of dye?

• at the bottom of cup
• in the color
• at the top of cup 
• no concenteraion gradient

During osmosis

• water moves from high to low concentration
• large or oddly shaped molecules move across a cell membrane
• water moves when energy is used
• proteins are built

What is the definition of  Selective Permeability?

• The movement of materials across the cell membrane that requires NO ENERGY from the cell.
  
• The movement of materials through (or across) the cell membrane
  
• The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.
• The movement of molecules from an area of high concentration to a area of low concentration 
  

A person should never drink salty water because their cells would

• shrink
• expand

Equal percentage of solutes inside and out. 
Concentration of substances is the same. 

• hypotonic
• isotonic
• nucleus
• hypertonic

Particles are too large to enter the membrane.
Need help from channel proteins. No energy required.

• active transport
• passive transport
• facilitated diffusion
• osmosis

When a cell is placed in a hypertonic solution, water

• moves from the inside of the cell to the solution
• moves from the solution to the inside of the cell
• moves equally in and out of the cell

What is the overall goal of ALL cellular transport?

• to make a gradient

• to maintain homeostasis

• to make the cells shrink

• to keep molecules where they are

When water moves across the cell membrane, is energy used?

• Yes, it is active transport

• Yes, it is passive transport

• No, it is active transport

• No, it is passive transport
