*Unit 3 Part 8: Mitosis Flashcards
Cells, Cell Transport, & Mitosis
Mitosis
The process of cell division that creates two genetically identical daughter cells for one parent cell
What form of reproduction is mitosis?
Asexual reproduction
How many chromosomes does each daughter cell have?
The same number as the parent cell
What is the main goal of mitosis?
2 things
Growth and Repair
Where does mitosis occur in comparison to interphase?
Mitosis occurs AFTER interphase
Where does cytokinesis occur in comparison to interphase?
Cytokinesis occurs BEFORE interphase
Are interphase and cytokinesis part of mitosis?
no
What is interphase?
when normal cell processes occur
What does the cell do when it is ready to divide?
It copies chromosomes in S phase
What happens during prophase?
- Chromosomes condense and become visible
- Nuclear membrane breaks down
- Spindle attatch to chromatids
What happens during metaphase?
- Chromosomes line up in the middle at the metaphase plate
What happens during anaphase?
- Identical chromatids are pulled apart to opposite ends of the cell
What happens during telophase?
- Two nuclei reform
- Chromosomes begin to “relax and unwind”
What happens during cytokinesis?
the cytoplasm divides
How does cytokinesis work in plants
A cell plate forms
