100

What is Osmosis?

Osmosis is the diffusion of water through a thin membrane.

100

How do diffusion affect the cell?

Diffusion affects a cell when a cell's interior has less minerals/nutrients than the exterior, or an area of higher concentrated to lower concentration. The substance will drift through the cell membrane.

100

How does the cell membrane affect osmosis and diffusion?

Osmosis and diffusion are processes in which water or other molecules move in or out of a cell, the cell membrane controls what materials go in, out, or are blocked.

100
What is homeostasis?
the ability of the internal systems of an organism to maintain normal balance, despite external conditions For example when you sweat or shiver
200
Why is the cell membrane important to Osmosis?
The cell membrane allows water and other needed liquids in and out of the cell.
200
What is diffusion?
Diffusion is the dispersion of substances in a gas or liquid
200
How does the cell membrane protect the cell?
The cell membrane surrounds a cell and controls which substances can enter or leave the cell.
200
What is a molecule?
two or more atoms bonded together
300

What does Osmosis do for cells?

It provides a way for cells to maintain an internal balance

300

Which of the choices below isn't diffusion? Smelling the food in the kitchen for your bedroom, a tea bag releasing tea into water or hearing your friend yell from across the classroom

Hearing your friend yell from across the classroom

300

What type of membrane is the cell membrane?

Semipermeable membrane

300
How do molecules move during diffusion and osmosis in cells?
Molecules move during diffusion by spreading out, at the start there is a high concentration of molecules in one area, then little concentration everywhere. The molecules move during osmosis in the same way, with water.
300

What is diffusion?

The transfer of particles from high to low concentration

400
What material/liquid is always present during osmosis? HINT: It could be what is being brought into the cell, getting put out, or blocked.
Water
400
How does Diffusion help the cell?
Diffusion is essential for cells to bring nutrients and releasing wastes WITHOUT spending energy.
400
What is the cell membrane?
the boundary that surrounds a cell and controls which substances can enter or leave the cell
400

DOUBLE POINTS:Is the cell membrane involved in diffusion or osmosis?

The cell membrane is involved in osmosis because is has tiny pores which let the molecules in and out of the cell

400

What is the cell membrane?

A semipermeable membrane that allows certain substances to pass through
500

Name a real life example of Osmosis

Ex:

500

Name a real Life example of diffusion.

dye in water perfume any smell teabags Etc. We will tell you if your group is correct

500

What is a permeable membrane?

a membrane which lets all molecules in and out

500

Why are diffusion and osmosis important to cell function?

Diffusion and Osmosis are important to a cell's function because it is the way nutrients and minerals are transferred into a cell.

500

What is osmosis

The diffusion of water across a membrane from high to low concentration
