Cell Division Flashcards
Is an irreversible increase in size and or dry mass
Growth
What are the three main stages of cell division
Interphase, Mitosis, Cytokinesis
In this phase, the cell grows and matures
Interphase
Interphase is divided into three stages:
G1, S, and G2
Is characterized by cell grow and development
G1
The DNA contained in the cell’s chromatin is duplicated
S
The Synthesis of Organelles
G2
Is the division of a somatic cell into two daughter cells
Mitosis
Are cells that have a body cell as a distinct reproductive celle
Somatic Cell
Is a layer of cells between the xylem and the phloem of plants that is responsible for the secondary growth of roots and stems.
Cambium
The phase where the nucleolus disappears
and the chromosomes begin to be visible
Prophase
The two centrosomes, that is, the two organelles, near the nucleus in the cytoplasm of organisms that controls the organization of microtubules (e.g proteins, I.e cytoskeleton), are separately located outside the nucleus of the cell, each moving towards the two opposite poles
Prophase
The chromosomes, each made up of two chromatids, come to lie at the equator of the cell where each chromosome is attached to a spindle fiber at the centromere.
Metaphase
The two chromatids in each chromosome separate at the centromere and begin to move toward opposite poles attached to the spindle fibers.
Anaphase
On the arrival of the chromatids at the poles. At each pole, a new daughter nucleus is reconstituted containing the number of chromatids equal to the number of chromosomes in the parent cell. At this point, a new nucleus is formed and while this is going on, the spindle gradually breaks down.
Telophase
