Lesson Plan on Tissues and Membrane

Cell Membrane

Multiple Choice

What forms the channels and pumps in the phospholipid bilayer?

• carbohydrates
• proteins
• hydrophilic heads 
• lipids

Multiple Choice

Describe the movement of molecules in the illustration.

• Molecules are moving from a lower concentration to a higher concentration. 
• Molecules are moving from a lower concentration to a higher concentration. 
• Molecules are moving from a higher concentration to a lower concentration and then from a lower to higher concentration.
• Molecules are moving from a lower concentration to a higher concentration and then from a higher concentration to a lower concentration. 

Multiple Choice

The cellular process in which materials are moved across a membrane from an area of low concentration to an area of high concentration is called

• Osmosis
• Simple Diffusion
• Active Transport
• Passive Transport 

Multiple Choice

In passive transport, the concentration gradient goes from..

• Low to low

• High to low

• Low to high

• High to high

Multiple Choice

The function of the plasma membrane is....

• to regulate what enters and leaves the cell.
• fight bacteria and viruses that enter the cell.
• provide rigid support and protection to the cell.
• make sure each cell can move

Multiple Choice

What is this image?

• cell membrane
• proteins

• lipids

Multiple Choice

All cells have a:

• Nucleus
• Plasma membrane
• Cell wall
• Buddy

Multiple Choice

What does semi-permeable mean?

• Only some things can move through membrane
• Nothing can move through membrane
• Reagan can move through membrane
• Membrane connot be moved through

Multiple Choice

If a red blood cell is put in a salt solution, what will happen to the cell?

• It will shrivel.
• It will swell and burst.
• It will shrivel and swell and burst
• It will do nothing at all

Multiple Choice

What is homeostasis?

• How the body releases oxygen
• Passive transportation 
• How the body regulates itself for survival (keeping a stable internal environment)
• Active transport

Multiple Choice

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)
• Active uses ATP (energy) and passive does not need energy
• Active stores transport proteins and passive releases 
• Active uses hormones and passive does not
