Slide 1

Cell Division Mitosis

Slide 2

Cell Division What is it? Why do Cells isn't that right? Why is it critical to me?

Slide 3

Cell Division Also known as Mitosis Takes put in Regular Body Cells Keeps Cells Living and Growing

Slide 4

Phases of Mitosis

Slide 5

Mitosis The Basic Phases of a Cell's Life: Interphase Prophase Metaphase Anaphase Telophase Cytokinesis

Slide 6

Interphase The longest phase of a Cell's life The time spent between divisions Produces all materials required for development Preparation for division

Slide 7

Part of Interphase is otherwise called the G1 Phase of the Cell Cycle (Growth Phase)

Slide 8

The Second some portion of Interphase is known as the S Phase of the Cell Cycle (Synthesis Phase – when DNA copies)

Slide 9

The third piece of the Cell Cycle, G2 , is only a checkpoint to ensure the DNA is right. Next stride – Mitosis

Slide 10

Mitosis: Cell Division The last some portion of the Cell Cycle is called Mitosis and has 4 stages amid which the phone partitions into 2 cells

Slide 11

Prophase The Cell starts the division procedure The nucleolus vanishes, The atomic film breaks separated

Slide 12

3. The chromosomes get to be distinctly noticeable 4. The axle contraption structures and joins to the centromeres of the chromosomes

Slide 13

Metaphase The Second Phase of Mitosis The Nuclear Membrane is totally gone 2. The copied chromosomes line up along the cell's equator.

Slide 15

Anaphase The third period of Mitosis Diploid arrangements of girl chromosomes isolate They are pushed and pulled toward inverse posts of the cell by the axle filaments

Slide 16

Spindle Fibers

Slide 17

Telophase The atomic layer and nucleoli (core) change. Cytokinesis is almost entire,

Slide 18

The Cell Plate starts to shape The Cell gets ready for finial division

Slide 19

Cytokinesis – The last phase of Mitosis The cytoplasm, organelles, and atomic material are uniformly part and two new cells are framed. Cell Plate

Slide 20

The two new cells – each precisely like the other – are called Daughter Cells

Slide 21

Quick Review: The accompanying slides are drawings of the phases of Mitosis. On your notes, please draw each stage and mark it.

Slide 22

Interphase – The Cell spends the greater part of its life here, developing and working. Amid the S Phase of the Cell Cycle, the DNA repeats, in foresight of Mitosis

Slide 23

In Early Prophase of Mitosis the Chromosomes get little, centrioles move to the shafts of the core, and axle strands create Chromosomes comprising of 2 Sister Chromatids Pair of Centrioles Spindle Fibers

Slide 24

Late Prophase happens when the Nuclear Envelope crumbles and axle filaments start to move Chromosomes toward the focal point of cell. Shaft Fibers Chromosomes

Slide 25

During Metaphase the Chromosomes line up crosswise over focus of the phone, likewise called the equator, or Metaphase plate. Axle Fibers Equator, or Metaphase Plate Chromosomes

Slide 26

In Anaphase the Chromatids that make up every Chromosome move separated and go to inverse closures of cell axle Daughter Chromosomes Chromatid Chromosome

Slide 27

In Telophase an envelope encompasses each arrangement of Chromatids to frame new Nucleus and the Cytoplasm begins to gap Cleavage Furrow

Slide 28

Cytokinesis happens when the Cytoplasm partitions and two cells with indistinguishable hereditary material are shaped Daughter Cells

Slide 29

Quick Review – Place Cells in Mitosis Order A B C D E

Slide 30

Interphase Quick Review: Identify What occurs in each period of Mitosis: Prophase Metaphase Anaphase Telophase

Slide 31

Why Do Cells Divide? The bigger a cell turns into, the more requests the cell puts on it's DNA. It additionally experiences more difficulty sufficiently moving nourishment and squanders over its cell film.

Slide 32

Food goes in The greater the cell gets the harder it gets to be to move nourishment and waste over the film Waste goes out

Slide 33

Protein Pumps This happens in light of the fact that the surface zone and volume proportion does not remain the same as the cell measure increments.

Slide 34

The cell's capacity to either get substances from the outside or dispose of waste from within is identified with the surface zone of the cell layer. (outside)

Slide 35

How much nourishment and other material is required, and how much waste the cell creates and needs to dispose of, is identified with the volume of the cell. (inside)

Slide 36

As a cell gets greater there comes a period when its surface territory is not sufficiently substantial to meet the requests of the cell's volume and the cell quits developing.

Slide 37

So, once cells achieve a specific size they should isolate to keep on functioning – or they will never again have the capacity to take in supplements and dispose of waste.

Slide 38

Why Is Cell Division Important? 1. Every Living Thing are made of Cells

Slide 39

2. The Cell is the fundamental unit of Structure and Function in Living Things.

Slide 40

3. All Cells originate from previous Cells
