Chapter 3 Flashcards
Function of mitosis
To move all of the materials in the parent cell to get ready for division
Phases of mitosis (4)
Prophase, metaphase, anaphase, and telophase
Steps of the cell cycle (6)
Interphase, prophase, metaphase, anaphase, telophase, cytokinesis.
Interphase
The cell carries out its normal functions and DNA is duplicated
Prophase
The membrane around the nucleus starts to disappear and the centrioles move to opposite sides.
Metaphase
The chromosomes line up in the middle of the cell
Anaphase
Chromatids split, leaving two identical chromosomes. These are pulled to opposite sides.
Telophase
A new membrane forms around each group of chromosomes.
Cytokinesis
The cytoplasm is divided and the membrane pinches, leaving two new cells. A new membrane forms around each new cell.
Which cells undergo mitosis?
Only eukaryotic cells
Describe the two new daughter cells from mitosis.
Each has an exactly identical set of DNA, which helps them function for growth, development, and repair.
What is the result of cell division?
Two new daughter cells
What are the three reasons your cells divide?
Growth, development, and repair.
How does cell division lead to growth?
The cells divide and make you bigger because you have more cells. Larger organisms don’t have larger cells, they just have more.
What happens to the cells in your body when you are an adult?
The divide for repair and not for development or growth. You are already done developing and growing.
