Movement to materials in and out of cells: Biology  9th Grade

What is Diffusion?

What factors affect the speed of diffusion?

Where does diffusion happen faster?

If you have a box filled with a type of gas (i.e. bromine), and there's a wall between the 2 sides of the box.
Side A (left) has more than Side B (right).
What would happen if you removed the wall?

What is the overall movement of this example of dffusion?

Is this always the case? Explain why.

What would happen if the box is left for a while?

Where is diffusion relatively fast?

What would happen if cells were large??

Why do we have systems in larger organisms? What processes do they help?

List the properties of a cell memebrane.

List the parts of a cell membrane.

What is the cell membrane?

Give the definition of this word:
PERMEABLE

Give the definition of this word:
IMPERMEABLE

Give the definition of this word:
SELECTIVELY PERMEABLE

It depends of the properties of FAT and PROTEINS, whether a substance can enter a cell or not. T or F

What are the four types of diffusion?

What is simple diffusion?

Can Simple Diffusion transport UP a concentration gradient?

True or False: Simple Diffusion is a passive process.

What does simple diffusion use to transport?

What is simple diffusion used for?

List the size and some examples of material that simple diffusion can process.

What is Facilitated diffusion?

Is Facilitated diffusion specific?

Facilitated diffusion a not passive process. T or F

List the things that facilitated diffusion can transfer.

What is active transport?

List the characteristics of active transport.

What is bulk transport?

What is special about Bulk Transport?

What is Endocytosis?

What is Exocytosis?

What are the 2 types of Endocytosis?

List the characteristics of Phagocytosis

List the characteristics of Pinocytosis

What is OSMOSIS?

What are osmosis model cells?

Model Cells are very permeable to small molecules like water. T or F

What are they less permeable to?

Blood cells are impermeable to water. T or F

What is another component they are relatively impermeable to?

If a blood cell is in a hypotonic solution, what will happen?

If a blood cell is in a hypertonic solution, what will happen?

What if it was placed in a ISOTONIC solution?

What makes plant cells different from animal cells?

What makes a plant, "TURGID?"

Why is turgidity of a plant so important?

What makes a plant, "FLACCID?"

What is the term used to explain how, 'the cell shrinks away from the plant's wall'?

How do the molecules move?
