Cell Division And Mitosis Flashcards
Whats in cell division
Mitosis
Cytokinesis
Mitosis
the process of nuclear division
where the number of
chromosomes is conserved
from one generation to the next
cytokinesis
Cytokinesis
the process of cytoplasmic
division that occurs after
mitosis has happened
What are the 4 phases of mitosis
Prophae, metaphase, anaphanze and telophase
Phrophase
The chromatin condenses into chromosomes. The centrioles separate, and a spindle begins to form. The nuclear envelope breaks down
Metaphase
The chromosomes line up across the center of the cell. Each chromosomes is connected to a spindle fiber at its centromere
Anaphase
The sister chromatids separate into individual chromosomes and are moved apart
Telophase
The chromosomes gather at opposite ends of the cell and lose their distinct shapes. Two new nuclear envelope will form
Mitosis is the process where a cell divides to create two identical daughter cells, ensuring each has the same number of chromosomes as the original cell.
What happens during mitosis
Cytokinesis in animal cells
process where the cell membrane pinches in, forming a cleavage furrow, which deepens until the cell splits into two identical daughter cells. This happens after mitosis to complete cell division.
Cytokinesis in plant cells
process where a cell plate forms in the middle of the cell. This plate grows outward until it becomes a new cell wall, fully dividing the cell into two identical daughter cells. This happens after mitosis to complete cell division.
Whats chromosomes made from
Proteins and DNA
What us an cleavage furrow
a groove that emerges in the plasma membrane between the daughter nuclei as part of the process of cell division
