5. Label the pictures with the cell division phases: interphase, prophase, metaphase, anaphase, telophase, cytokinesis


Anaphase

ProphaseMetaphaseCytokinesis

Telophase Interphase

Events Cell Cycle Phase

Chromosomes are replicated

Spindle fibers pull chromosomes apart to opposite end of the cell

Nuclear membrane dissolves

Increasing cell size and grow

Production of many organelles and molecules

Centrioles and spindle fibers become non-visible

Chromosomes line up in the middle of the nucleus

Spindle fibers attach to each chromosome at the centromere

Wind DNA ( chromatin) into chromosomes

Cell splits with its own set of chromosomes

Nuclear membrane forms

DNA unwinds into chromatin

A. Chromosomes line up in the middle of the nucleus

B. Chromatids move to opposite end of the cell

C. Nuclear membrane dissolves

D. Cell splits with its own set of chromosomes

E. Cell grows and DNA replicates

Do Now:

1. Interphase

2. Prophase

3. Metaphase

4. Anaphase

5. Telophase

• Spindle fibers pull chromatids apart to opposite end of the cell

• DNA is replicated

• Nuclear membrane dissolves

• Increasing cell size and grow

• Production of many organelles and molecules

• Chromosomes line up in the middle of the cell• Spindle fibers attach to each chromosome at the centromere

• Wind DNA ( chromatin) into chromosomes

• Nuclear membrane forms• DNA unwinds into chromatin

Interphase

Prophase

Metaphase

Anaphase

Telophase

• Centrioles and spindle fibers become visible

• Centrioles and spindle fibers become non visible


Cytokinesis • Cell splits with its own set of chromosomes

Mitosis

Number of cell division?

Exchange of genetic material between chromosomes?

Number of functioning cell produced from the original?

Number of chromosomes of daughter cells compare to parent cells

How is the genetic material of final cells produced?

Function of cells produced?

One

No

Two daughter cells

Equal number

In human is 46 chromosomes

Identical as the original

• Growth or replacement of body cells

• Same as the parent cells
