Questions from class:
What is an example of a one celled eukaryotic organism?
What is an example of a one celled eukaryotic organism?
Paramecium and Euglena. (above in photo).
What is an example of a multicellular organism?
Human, fox, hippo, dog, cat, sunflower, tulip, etc.
Which of the examples above would use mitosis to grow, develop, and repair cells? Why?
Multicellular organisms. This is because if you do something to injure a single-celled organsim, it wouldn't be able to repair itself because all of the organelles and cytoplasm would spill out, WHEREAS, humans would just reproduce cells until the area is healed. Also, if single celled organisms went through mitosis it would turn into TWO organisms instead of just a new cell that isn't organism.

How would the other use mitosis?
They would use mitosis to reproduce and make a new organsim.
What would be true about the two resulting cells?
They would be exact genetic copies of the parent cell. This is because the DNA is exactly copied so they are exactly the same, so all parameciums look exactly the same.
In comparison: When humans reproduce, the children will look kind of the same as the parents but not exactly, because of two pairs of genes not one.

Is this true about any two cells we compare in a multicellular organism?
No. This is because they have different functions (liver cell vs. brain cells) so there are different amounts of organelles that are used for different things (ex. leaf cells need more chloroplasts to photosynthesize.)
In comparison: If I take 2 cheek cells they will look exactly the same
Other notes:
MITOSIS is reproduction for single celled organisms.
Mitosis is cellular REPRODUCTION for single celled organisms whereas, mitosis is cellular DEVISION for multi-celled organisms. This is because reproduction is the creation of a new organism.
The 4 parts of mitosis are: (not in this order)
Metaphase
Anapase
Prophase
Telophase
Parts of cell cycle (not necassarilly in this order)
Interphase
Mitosis
Cytokinesis
Chromatid: One side of a chromosome, that connected at the centromere.

The cell cycle also includes DNA replication and two growth phases.
