Organelles #4
Which organelles make proteins? and
Where can you find them (2 places)?

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
Osmosis and Membranes #2
Which type of macromolecule makes
up membranes?

The process of water moving through a
membrane to balance concentrations is
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
Which process do cells go through to
make an identical copy of themselves?
Answer: mitosis
Mitosis and Meiosis #2
What do we call the daughter cells
produced through meiosis?
Answer: gametes or sex cells
Mitosis and Meiosis #3
What do we call cells that have a two copies
of each chromosome?
(46 in humans)
Answer: diploid
Mitosis and Meiosis #4
How many chromosomes are there in
a haploid human cell?
Answer: 23
Mitosis and Meiosis #5
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
