- Sex cells are formed by which type of cell division?
- Skin cells are formed by what type of cell division?
- Gametes are produced by which type of cell division?
- Stem cells are special cells that can reproduce repeatedly and form exact copies of themselves. By what process do stem cells produce exact copies of themselves?
- A rooting hormone can be applied to the cut end of a plant stem and over time the stem will start to produce roots. This rooting hormone stimulates what type of cellular division? Explain your answer.
- Stem cells are special cells that can reproduce repeatedly and form exact copies of themselves. In what way are stem cells like a zygote?
- Identify 3 differences between mitosis and meiosis.
Answer Key/Rubric
- Mitosis
- Meiosis
- Mitosis
- Meiosis
- Mitosis
- Acceptable answers may include, but are not limited to:
- Mitosis because it is producing roots which are not made of sex cells.
- Acceptable answers include, but are not limited to:
- Stem cells and a zygote are both one cell large and can make copies of themselves that are identical to the cell they started with. Both can also differentiate into new types of cells.
- Acceptable answers include, but are not limited to:
- Mitosis creates skin cells
- Meiosis creates sex cells
- Mitosis creates cells that have the same number of chromosomes as the original cell
- Meiosis creates cells that have half the number of chromosomes as the original cell.
- Mitosis only divides the cell once
- Meiosis divides the cell two times.
