Stem cells/Osmosis/Diffusion
What do stem cells not have?
They do not have jobs
What stage does the Sister Chromatids separate?
Anaphase
This cell is made of microtubules and they appear during cell division.
Centrioles/Centrosomes
Materials move down a concentration gradient
Passive
Causes the cell to shrivel?
Hypertonic
Where are stem cells located?
Bone arrow
What phase makes identical copies
Interphase
This cell breaks down dead stuff like bacteria, and old parts of the cell. It can also do programmed death (apoptosis)
Lysosomes
Does not require energy
Passive
Same osmotic concentration as the cell
Istonic
Can stem cells cure cancer?
Yes
What is the 5th stage of the cell cycle
Telophase
This is a threadlike structure
Flagella
Tends to move large, polar molecules across the cell membrane
Active
Higher osmotic concentration than the cell
Hypotonic
Moves water
Osmosis
What stage do the spindle fiber connect? This is also the stage where the chromosomes line up in the middle of the cell.
Metaphase
This is an organelle in the cytoplasm of eukaryotic cells that contain enzymes enclosed in a membrane
Lysosomes
Materials move from high to low concentration
Passive
Causes cell to swell
Hypotonic
Moves small particles like O2 and CO2
Diffusion
What are the 3 stages that the cells go through?
1. Nucleolus
2. Rough ER
3. Golgi apparatus
True/False
Helps divide by pushing
Flase. It helps divide by pulling!
Requires energy
Active
Causes water to move into the cell
Hypotonic
