Steps of Mitosis 1. INTERPHASE (between) 2. PROPHASE (first) 3. METAPHASE (middle) 4. ANAPHASE (ana-banana-split) 5. TELOPHASE (two)
Chromosomes duplicate Chromosomes condense Chromosomes are now double-stranded and held together by a centromere.
Chromosomes are fully visible Nuclear membrane fades Centrioles (cowboys) move to opposite ends of the cell Spindle Fibers (ropes) form
Chromosomes line up in the center of the cell Centromeres attach to the spindle fibers.
Strands of chromosomes separate and move away from each other.
Centrioles & spindle fibers disappear Chromosomes stretch out again Nuclear membrane forms Cytoplasm pinches in to form two identical cells.
Results One cell = Two cells (exactly alike) with the same number of chromosomes.

The Science of Microbiology (9 minutes) 1. Why is the discovery of Archaea significant?
Cell Division (11 minutes) 1. How might stem cells be used in future research? 2. Describe the process of Mitosis and Meiosis.
Cell Cycle IPMATC. Cell Cycle 3 Parts: – Interphase – Mitosis Prophase Metaphase Anaphase Telophase – Cytokinesis.
Cell Cycle: M Phase Mitosis and Cytokinesis. Cell Division (M phase) Occurs in two stages – Mitosis (nuclear division) – Cytokinesis (cytoplasmic division)
Cell Division The Cell Cycle: Interphase Mitosis Cytokinesis.
The cell cycle and mitosis. Cells constantly reproduce exact duplicates of themselves. Why? Replacement Repair Growth.
Cell Cycle Vocabulary and Notes Biology. Centrioles – one of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope. Chromatid.
Cellular Reproduction. Mitosi s I – Interphase: Period between division DNA molecules duplicate Single strands (chromatin threads) X shaped chromosomes.
The Cell Cycle. Chromosomes Carry genetic information in eukaryotes Carry genetic information in eukaryotes Made of DNA and proteins Made of DNA and proteins.
The Cell Cycle Mitosis. The Cell Cycle The regular sequence of growth and division that cells undergo.
Meiosis. Meiosis is the type of division which: 1. Reduces the chromosome # from diploid to haploid 2. Is used to produce gametes: eggs and sperm.
Mitosis & Cytokinesis Cell Growth and Reproduction Ch. 8.2.
Cell Division and Mitosis -Chapter 9- Honors Biology Program Mountain Pointe High School.
Mitosis: The Dance of the Chromosomes. Once Interphase is done the cell is ready to begin Mitosis. Mitosis is when the cell divides.
Cell Division. Two Parts of Cell Division (1) Mitosis – (2) Cytokinesis.
Meiosis and Sexual Reproduction. Sexual Reproduction Diploid Cell A cell that has chromosomes located in similar pairs. These cells are called body cells.
Mitosis and Cytokinesis B-2.6 Summarize the characteristics of the cell cycle: interphase (called G1, S, G2); the phases of mitosis (called prophase, metaphase,
CELLS AND HEREDITY. Introduction November 30, 2010 New Vocabulary List – back of spiral –Title of new list – Heredity –DNA -- a molecule found in cells.
Section 10-2 Cell Division Biology I Flora. Two Parts of Cell Division (1) Mitosis – division of the cell nucleus (2) Cytokinesis – Division of the cytoplasm.
I.Sexual Reproduction --two parents combine. 1. The sex cell from the male parent is sperm. a. Sperm head is almost all nucleus (genetic info) 2. The.
N-6 Cell Division What do cells spend their time doing? Why do they do this?
Phases of Cell Division Interphase (stage between cell division) Interphase (stage between cell division) Prophase Prophase Metaphase Metaphase Anaphase.
1 1 Mitosis and the Cell Cycle Pgs Big Idea: Mitosis is the process in which the nucleus divides to form two new nuclei and two cells with identical.
Cell Division Mitosis Chapter 10. Why do cells divide, rather than continually grow forever? The larger a cell becomes, the more demands the cell places.
What is Mitosis?. Mitosis is Cell Division A regular cell copies its chromosomes, then the cell divides and the new cell receives a nucleus with.

Cell Growth and Division Honors Biology Chapter 10.
Cell Division and Mitosis. Understanding Cell Division What instructions are necessary for inheritance? How are those instructions duplicated for distribution.
Meiosis Pgs Human body cells have 46 chromosomes Meiosis - General Overview Sexual Reproduction and Genetics Each parent contributes 23 chromosomes.
MITOSIS. How do little elephants grow up to be BIG elephants?
Cell Cycle Cell Growth and Division. 2. Why do cells divide? If the cell is too big: If the cell is too big: Too much demand is placed DNA Too much demand.
Aim: How does asexual reproduction result in offspring that are identical to the parent? Major Understanding In asexually reproducing organisms, all the.
