Reproduction- Cell Division

Zygote

Fertilized Egg

Interphase

When a cell is not dividing; the longest phase of a cell’s life cycle

G1

Cell grows, makes needed organelles and cytoplasm to function normally

Synthesis

The Chromosones replicate to two sets of DNA

Growth 2

Cell prepares for mitosis by doubling all organelles

Mitosis

Parent Cell divides

Cell Division has two main steps:

Mitosis and Cytokinesis

Mitosis consists of four steps

Prophase, Metaphase, Anaphase, Telephase

Cytokinesis

The divide of the cytoplasm

DNA is stored in…

…Chromosones

Chromosones take the form of ____ in interphase.

Chromatins

When a cell divides, it divides in…

half

During S & G2, the cell has ___ the amount of genetic information as the G1 phase.

double

After it replicates and prepares for cell division…

the chromatids condenses into an x shape

Each half of the chromosome is known as the…

…sister chromatid

The protein disc in the middle is called the…

centromere

PMATC

Cell Division

Prophase

Chromosones condense, nuclear envelope and nucleolus disappear, centrosomes migrate to opposite sides of the cell.

Centrosomes

Micro-Tubule Organization Center

In animal cells, a pair of __ are apart of the chromosome.

centrioles

Metaphase

Chromosones migrate to the center (metaphase plate) and spindle fibers attach at the kinetochore. Each sister chromatid is attached to a spindle fiber.

Spindle Fiber

Microtubules that attach to the chromosome and pull chromatids apart.

Anaphase

Spindle Fibers pull chromosomes apart

Cytokinesis

Cell plate splits apart

Animal Cells have…

cleavage furrowsP

Plant cells…

have cell plate

Mitosis only occurs in…

eukaryotes

Prokaryotes divide through…

binary fission
