Osmosis and Membranes #1
The cell membrane allows small molecules,
like water and oxygen, to pass through it.
Other molecules are blocked. What is this
type of membrane called?
Answer: Semi-permeable

called…
Answer: Osmosis
Osmosis and Membranes #4
What would happen to a cell full of
fresh water if we put it in salt water?
Answer: the water would go out of
the cell and the cell would shrink
Osmosis and Membranes #5
Which types of cells have membranes?
Answer: Both plant and animal cells
(plants also have cell walls)
Mitosis and Meiosis #1

In mitosis and meiosis, how many times
does the DNA replicate and how many
times does the cell divide?
Answer:
Mitosis – replicates once, divides once
Meiosis – replicates once, divides twice
