100
What structure of a cell controls the flow of materials into and out of a cell?
Cell membrane, plasma membrane, phospholipid bilayer
100
What is the phase of the cell cycle when DNA and organelles are split up in a cell?
Mitosis
100
What is the step in mitosis when the chromosomes are lined up in the middle?
Metaphase
100
What is the cell cycle?
The process of a cell growing and dividing.
100
A carrot is left in salt water. What happens to the carrot (specifically the cells)?
The water is drawn out of the cells by the salt. The carrot will shrink
200
What is it called when water moves in and out of a cell?
Osmosis
200
What is it called when a cell stops and "checks" to make sure it is ready for the next step?
Checkpoint
200
What is the step of mitosis when the two new nuclei are forming?
Telophase
200
What kinds of cells divide out of control?
Cancer cells
200
An orange is floating in orange juice. What kind of solution is the juice? (Which -tonic?)
Isotonic
300
What is it called when materials ("stuff") move around/spread out?
Diffusion
300
What is the long phase when a cell grows and copies its DNA?
Hint: between divisions
Interphase
300
What is the step of mitosis when the chromosomes are pulled apart?
Anaphase
300
What is it called when a cell destroys itself (usually something has gone wrong)?
Apoptosis
300
What does a cell do if it fails at one of the checkpoints? (2 options, give both)
1) Wait and try to fix itself
2) Self-destruct (Apoptosis)
400
What is it called when the concentration inside of a cell is higher than outside a cell?
Hypotonic
400
Which step is DNA copied in?
Interphase (S step)
400
What is the step of mitosis when the nucleus is broken down and spindles are formed?
Prophase
400
What is a chromatid?
Half of a chromosome
400
Why is it important for a cell to have an M checkpoint (before anaphase)? (hint: what happens in anaphase?)
To make sure the daughter cells have the right number of chromosomes.
500
What is it called when there is an equal concentration in and out of the cell?
Isotonic
500
What is the phase called when a cell splits into two new cells?
Cytokinesis
500
Why do cells do mitosis?
Answers will vary.
Ex. To make more cells, to help us heal, grow
500
What is chromatin?
Unraveled/unwound DNA. "Spaghetti DNA"
500
What would happen to a pair of shelled (shell pulled off) eggs if you left one in a cup of salt water and the other in a cup of tap water?
The salt water one would shrink, the tap water one would grow.
