CELL TRANSPORT NOTES

​

PART 1: MEMBRANE STRUCTURE​

Cell membranes are made of fats called phospholipid​

Every phospholipid has 2 parts- a head and a tail​

​

Part 1: Membrane Structure​

The head ALWAYS touches the water and the tail ALWAYS avoids water.

The cell membrane is always moving. This movement is called FLUIDITY. ​

​

Match

Cell Membrane Structure:

Match the following

• Phospholipids

• Head and tail

• Head

• Tail

• Fluidity

Cell membranes are made of

2 parts of phospholipid

Touches water

Doesn't touch water

Always moving

• Cell membranes are made of

• 2 parts of phospholipid

• Touches water

• Doesn't touch water

• Always moving

Draw

Draw a phospholipid below

CELL TRANSPORT:

The cell membrane can move materials in and out of the cell​

Selective permeability= choosing what comes in and out

The cell has 2 types of transport: Passive and Active​

​

​

Match

Cell Transport:

Match the following

• Selective permeability

• Passive transport

• Active transport

Choosing what comes in and out

No energy used to move molecules

Uses energy to move molecules

Picture of active transport

Picture of passive transport

• Choosing what comes in and out

• No energy used to move molecules

• Uses energy to move molecules

• Picture of active transport

• Picture of passive transport

PASSIVE TRANSPORT

• No energy is used

• Molecules move from high concentration to low concentration until equal​

ACTIVE TRANSPORT

• Energy is used

• Molecules move from LOW concentration to HIGH concentration; uneven molecules on each side

Match

Match the following pictures to their transport type

OSMOSIS of water

FACILITATED DIFFUSION through a protein

PROTEIN PUMP

ENDOCYTOSIS of food

• DIFFUSION of molecules
