Unit 3 One Pager Review

Imagine Oliver, Henry, and Charlotte are in a room filled with balloons. The balloons start to move from one side of the room where there are many, to the other side where there are fewer. What is this process called that describes particles moving from higher to lower concentrations?

• Homeostasis

• Diffusion

• Active Transport

• Osmosis

Which type of transport is specific to the movement of water?

• Diffusion

• Facilitated diffusion

• Osmosis

• Active transport

Nora, Zoe, and Michael are on a science adventure! They stumbled upon a question they can't solve. Can you help them? How does active transport move materials?

• Does it move from higher to lower concentrations, like a waterfall flowing down a mountain?

• Or does it go against the concentration gradient, like a salmon swimming upstream?

• Maybe it uses protein channels, like a train using its tracks?

• Or does it move materials directly through the membrane like sand slipping through a sieve?

Arjun, Elijah, and Evelyn are on a science adventure! They stumbled upon a cell and saw a fascinating process where the cell was taking in materials through pockets in its membrane. Can you help them identify this process?

• Molecular transport

• Simple diffusion

• Endocytosis

• Exocytosis

Imagine Olivia, Kai, and Liam are tiny scientists exploring the inside of a multicellular organism! Can you guess one way they might see the cells helping the organism maintain homeostasis?

• By becoming specialized for particular functions

• By communicating with each other

• By dividing rapidly

• By not making a one pager

In an isotonic solution, describe the concentration of solutes?

• Higher inside the cell

• Higher outside the cell

• The same inside and outside the cell

• Lower inside the cell

Arjun, Mason, and Isla are having a debate about what happens to a cell in a hypertonic solution. Arjun thinks it swells, Mason believes it shrinks, and Isla says it stays the same. Who do you think is correct?

• Arjun (It swells)

• Mason (It shrinks)

• Isla (It stays the same)

• None of them

What happens to a cell in a hypotonic solution?

• It swells

• It shrinks

• It stays the same

• It bursts

This image is showing a cell in what type of solution?

• Isotonic

• Hypotonic

• Hypertonic

• Osmotic

Which one is the correct order for levels of organization, from smallest to largest (most complicated)?

• Tissue, organ, cell, organ system

• Organ system, organ, tissue, cell

• Cell, tissue, organ, organ system

• Cell, organ, tissue, organ system
