​Cell Transport

​The movement of substances across the cell membrane without using energy from the cell.

​Examples:

1. diffusion

2. facilitated diffusion

3. osmosis.

​​

​(does not require energy​)

​​Passive Transport

Cell Membrane

The cell membrane is the border that determines what enters and exits the cell.; made of LIPIDS

The cell membrane is selectively permeable, or semipermeable, meaning only certain molecules can pass through​

The movement of molecules occurs by either passive or active transport.​

​Diffusion is the movement of particles from a area of higher concentration to an area of lower concentration.

​beginning

​after 5 mins

Osmosis

​Osmosis is the diffusion of water across the cell membrane from HIGH concentrations to LOW concentrations.​

Passive Transport

HYPER = HIGHER Solute concentration; water moves OUT

​

HYPO = LOWER solute concentration; water moves IN

​

ISO = EQUAL solution concentration; water moves IN and OUT​

​

Osmosis (cont.)

Movement of molecules from a LOW to HIGH concentration WITH energy (ATP)​

​

Active

Transport

Multiple Choice

Movement of materials from high to low concentration through a protein channel. 

• Passive Transport
• Active Transport

Multiple Choice

What is it called when molecules move across the cell membrane from an area of high concentration to an area of low concentration through a carrier protein?

• Diffusion
• Osmosis
• Active Transport
• Facilitated Diffusion

Multiple Choice

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

Multiple Choice

What is the cell membrane primarily made of?

• Phospholipid bilayer

• Protein bilayer

• Nucleic acid bilayer

• Carbohydrate bilayer

Multiple Choice

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.

Multiple Choice

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

Multiple Choice

Looking at this diagram, which way would the blue particles move?

• To the left

• To the right

• The particles wouldn't move

Multiple Choice

In passive transport, .............

• energy is required

• energy is not required

Multiple Choice

In active transport, .............

• energy is required

• energy is not required

When you get cold many systems work together to warm you up.

Integumentary system-You skin feels the change in temperature.

Nervous system- Nerves in your skin send signals to the brain telling you that it is too cold.

Muscular system-Your muscles contract to make goosebumps and you shiver creating heat.

Multiple Choice

Maintaining body temperature is an example of a:

• negative feedback loop
• positive feedback loop

Multiple Choice

The _______ system delivers oxygen and nutrients to every cell in the body.

• Circulatory

• Lymphatic

• Integumentary

• Nervous

Explanation Slide...

The heart pumps blood through the circulatory system.

Multiple Choice

The heart pumps blood through this system.

• respiratory
