Benjamin, Ava, and Liam are observing a cell under a microscope. They notice a particular transport process happening in the cell. What is the correct description of the transport they are observing in the image?

• small molecules crossing the lipid bilayer (diffusion)

• large molecules crossing through a protein (facilitated diffusion)

• many molecules coming into the cell using a membrane vesicle (endocytosis)

• many molecules coming out of the cell using a vesicle to fuse with the membrane (exocytosis)

Imagine Jackson and Mason are having a race. Jackson is using a bike (active transport) and Mason is running (passive transport). What is the main difference between them? One requires (a)   , while the other does not.

Abigail, Elijah, and Mason are having a fun science experiment with dye. Can you guess where there is a low concentration of dye in their setup?

• at the bottom of the cup they are using

• in the color they chose

• at the top of their cup 

• there is no concentration gradient in their setup

Imagine Oliver, Ava, and David are tiny astronauts exploring a cell! They come across a cell organelle that helps the cell maintain homeostasis by controlling what substances may enter or leave the cell. Can you guess which organelle they've discovered?

• vacuole

• nucleus

• cell membrane

• cell wall

Maya, Ethan, and Aria are observing an animal cell placed in a hypertonic (salty) solution. What will happen to the cell?

• Stay the same

• Shrink- get smaller

• Swell- get bigger

Oliver, Harper, and Emma were having a friendly competition to see who could identify what happened to red blood cells under a microscope. They saw that the blood cells exploded! What would you say happened?

• The cells were placed in a hypotonic solution.

• The solution was isotonic.

• The solution was hypertonic.

Osmosis is specifically.....

David, Liam, and Noah are having a debate about osmosis. Can you help them figure out what osmosis is?

• diffusion of water molecules through a semi-permeable mebrane from an area of low concentration to an area of high concentration

• the diffusion of particles from an area of high concentration to an area of low concentration

• diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration

• the diffusion of particles from an area of low concentration to an area of high concentration

Abigail, Zoe, and Mia are having a debate. They are trying to figure out where the water will go. Can you help them solve this mystery?

• Into the cell

• Out of the cell

• Equally in & out - it's isotonic

• There is no water
