Mitosis and Meiosis Flashcards
Phases of mitosis?
- Interphase
- Prophase
- Metaphase
- Anaphase
- Telophase
Describe interphase.
Cell goes about daily activites (growth and development)
Describe prophase.
Replicated chromosomes supercoil (shorten and thicken)
Describe metaphase.
Replicated chromosomes line up down the center of cell
Describe anaphase.
Replicated chromosomes are pulled apart by spindle to opposite poles of cell.
Describe telophase.
Two new nuclie form.
What is a diploid cell?
Contains two complete sets of chromosomes, one from each parent.
What is a haploid cell?
Contains one complete set of chromosomes.
At what phase in mitosis do the chromosomes line up on the equator of the cell?
Metaphase.
What are the 2 end products called from successful mitosis?
2 genetically identical daughter cells.
What is the process where the cell splits in cell division called?
Cytokinesis.
What are the only plant cells able to divide called?
Meristem cells.
What prevents plant cells from dividing like mammal cells?
Splitting is impossible due to the cell wall
Meristem cells have very thin walls.
What is a clone?
A (group of) organism/cell produced asexually from one ancestor, to which they are genetically identical.
What is the advantage of having genetically identical crops?
-Grow at same rate so will be ready to harvest at the same time.
