Active and passive transport

Cell membrane

As you follow along the slides, make sure you are taking notes.

1. Review parts of the cell

2. Differentiate between active and passive transport

​

Objective

Hotspot

Select the structure that carries out cellular respiration to give the cell energy.

Hotspot

Select the gel-like structure that fills up the cell, important biochemical reactions occur here.

Hotspot

Select the structure that give the cell its shape and controls movement of substances in and out of the cell

Hotspot

Select the structure that controls the cell and contains genetic material.

Multiple Choice

Which of the following best describes the main function of the cell membrane?

• It controls the movement of substances in and out of the cell.

• It produces energy for the cell.

• It stores genetic information.

• It synthesizes proteins.

As you watch the following video, remember to take notes.
You need to include the following concepts:
-active transport -gradient
-passive transport - vesicles
-diffusion -selectively permeable
-osmosis

Multiple Select

Which of the following are examples of passive transport in cells?

• Osmosis

• Diffusion

• Phagocytosis

• Pinocytosis

Multiple Choice

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

Multiple Choice

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

Multiple Choice

Permeable means

• things can pass through
• the concentration levels are different
• it is permanent
• things are stuck

Multiple Choice

Passive transport requires no

• concentration gradients
• osmosis
• motion
• energy

Multiple Choice

What is diffusion?

• when molecules move 
• when molecules move from a high concentration to a low.
• no movement 
• molecules move everywhere

Multiple Choice

Which type of transport requires an input of energy?

• Passive Transport
• Osmosis
• Simple Diffusion
• 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 

Multiple Choice

The movement of water through a semi-permeable membrane is called ___________.

• active transport

• respiration

• osmosis

• diffusion

Multiple Choice

_______ regulates what enters and leaves a cell.  

• Cell Membrane
• Nucleus
• Mitochondria
• Cytoplasm
