100
What is the layer around a cell called?
Cell Membrane
100
What is concentration?
How packed something is, how many particles/molecules per volume.
100
What does mitosis do?
Makes new cells
100
How many cells does mitosis make?
2
100
Why do we do mitosis?
To make more cells for growth and healing.
200
What is the "brain" of a cell? (Tells the cell what to do)
Nucleus
200
What does isotonic mean?
Same concentration
200
What does a cell do during metaphase?
Chromosomes line up down the middle
200
What is this a picture of?
metaphase
200
Which step is longest in the cell cycle?
Interphase
300
What fills the cell and holds the organelles in place?
Cytoplasm
300
What is the difference between hypertonic and hypotonic?
Hypertonic: high concentration of solutes
Hypotonic: low concentration of solutes
300
What does a cell do in telophase/cytokinesis?
Squeezes in the middle, making 2 new cells
300
Which step is this?
Telophase/Cytokinesis
300
What is one way cells get larger molecules in/out?
-Active transport
-Endo/exocytosis
400
What do ribosomes do?
Make proteins
400
What will happen to your cells if you go swimming in the ocean?
They will shrink (the salt will pull water out).
400
Which step is this?

Interphase
400
What happens in interphase?
The cell grows, copies its DNA, and does its job.
400
What's the difference between osmosis and diffusion?
Osmosis: water moves
Diffusion: other things move
500
What are three cell parts that both plants and animals have?
Ex. nucleus, cytoplasm, ribosomes, cell membrane, ER, golgi, vacuole...
500
Mia has a saltwater fish tank (ocean fish). Can she fill the tank with tap water? Why?
No.
The fishes' cells are used to salt water. Tap water would be hypotonic, and cause their cells to fill with water.
500
What happens in prophase?
Chromosomes condense (wrap into X shapes), nucleus breaks down, cell prepares to divide.
500
Which step: chromosomes pull apart, organelles separate to each side of the cell
Anaphase
500
What does this part do?
