H OW DO CELLS GROW AND D IVIDE ? Chapter 2 section 3
W HY DO THEY NEED TO DIVIDE 1. To make more 2. They also need to be efficient in getting materials around the cell 3. If they are too large then the cell will not function efficiently.
C ELL DIVISION Single cell- divide into two identical daughter cells Multi-cellular- also divide into two daughter cells when making new cells for growth or repair
M ITOSIS 1. The cell’s nucleus divides The nucleus contains DNA Used to code for all the genes in the organism Complex molecule consisting of three parts Found in the chromosomes
I NTERPHASE The cell copies its DNA and gets ready to divide
P ROPHASE Mitosis begins Short, compact chromosomes become visible Nuclear membrane dissolves
M ETAPHASE Pairs of chromosomes line up at the center of the cell
A NAPHASE The chromosomes separate The two halves move to opposite sides of the cell
T ELOPHASE Two new daughter cells are made Identical to the original Nuclear membrane appears
The Cell Cycle. Life Cycle of a Cell Before a growing cell becomes too large it divides The division results in two essentially identical cells called.
C ELL C YCLE Dr. Brasington. S OMATIC CELL DIVISION The process of a cell dividing into 2 identical daughter cells. Occurs when cells reach a certain.
How do baby elephants grow up to be adult elephants? What is happening to their cells?
C ELL D IVISION Function of Cell Division Mitosis & Cytokinesis.
1 1 Mitosis and the Cell Cycle Big Idea: Mitosis is the process in which the nucleus divides to form two new nuclei and two cells with identical DNA.
Mitosis How one cell becomes two. What is the purpose of Mitosis ?
Cell Division Mitosis. Overview of Mitosis 1 Cell (mother cell) divides into 2 Cells (daughter cells) Each new cell is an exact copy of the mother cell.
The cell cycle is divided into three stages: interphase, mitosis, and cytokinesis. During the cell cycle, a parent cell divides into two cells. The.
I can place in order pictures that show chromosome movement during cell division. I can classify methods of reproduction as sexual or asexual.
The Cell Cycle What is the cell cycle? What is mitosis – or cell division? What happens in each stage?
Chromosomes are copied (# doubles) Chromosomes appear as threadlike coils ( chromatin ) at the start, but each chromosome and its copy( sister chromosome)
If cancer is uncontrolled cell division…why would a cell divide in the first place? Brainstorm a list of reasons a cell would divide.
Interphase- Cells grow prepare for cell division by copying DNA (replication). DNA carries all information that all cells need to carry out their.
Mitosis: the process by which cells reproduce themselves, resulting in daughter cells that contain the same amount of genetic material as the parent cell.
1 1 Asexual Reproduction Mitosis DSQ: Mitosis is the process in which the nucleus divides to form two new nuclei. How does mitosis differ in plants and.
CELL DIVISION!!. There are two types of cell division. Mitosis – when an organism is growing, repairing or replacing cells EX: skin cells replacing dead.
How do little elephants grow up to be BIG elephants?
1 1 Asexual Reproduction (Mitosis) Mitosis is the process in which the nucleus divides to form two new nuclei. How does mitosis differ in plants and animals?
Cell Biology Mitosis, DNA, RNA. Mitosis (Cell Reproduction) This is the process of cell division resulting in the production of 2 daughter cells from.
1 1 Mitosis BODY Cell Division (Chapter 3 : 3 p.86-89) Mitosis is the process in which the nucleus divides to form two new nuclei. Mitosis differs.
1 1 Asexual Reproduction Mitosiss Mitosis is the process in which the nucleus divides to form two new nuclei. How does mitosis differ in plants and animals?
1 1 Cell Cycle. Skin cancer - the abnormal growth of skin cells - most often develops on skin exposed to the sun. Cell that reproduce by asexual reproduction.
1 1 Asexual Reproduction Mitosis Bell Work: Mitosis is the process in which the nucleus divides to form two new nuclei. How does mitosis differ in plants.
1 1 Asexual Reproduction Mitosis EQ: Mitosis is the process in which the nucleus divides to form two new nuclei. How does mitosis differ in plants and.
Does an animal get larger because each cell increases in size or because it produces more of them?
Chapter 9 Cellular Reproduction Section 1: Cellular Growth Section 2: Mitosis and Cytokinesis Section 3: Cell Cycle Regulation.
How Cells Divide. How do little elephants grow up to be BIG elephants?
E SSENTIAL Q UESTION : W HAT ARE THE FOUR STAGES OF MITOSIS ?
C E L L C Y C L E. The Cell Cycle Cells undergo an orderly sequence of events as they grow and divide. The sequence in the following slides show a typical.
How are elephants able to grow to such a large size?
2 2 Cell Cycle Cell cycle- The sequence of stages through which a cell passes between one cell division and the next. (The cycle begin growth and division.
How many stages of cell division do you see in this image?
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.
1 1 Asexual Reproduction Mitosis. How do little elephants grow up to be BIG elephants?
Cell Cycle and Mitosis. Cell Reproduction Cell division is the process by which new cells are produced from one cell. Cell division results in two.
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.
The Mitosis is also known as the cell division. This is made to repair dead cells and damages in your body, to grow and develop and to reproduct. This.
Section 5 The Cell Cycle. The Cell Cycle Humans go through stages of life. Babies, children, teenagers, and adults are all at different stages. Cells.
How many stages of cell division do you see in this image? Genetics Unit: Mitosis.
What is DNA? The genetic material located in the nucleus of the cell. It contains information needed for an organism to grow, maintain itself, and reproduce.
1 1 Asexual Reproduction Mitosis Mitosis is the process in which the nucleus divides to form two new nuclei. After cytokinesis, 2 cells are formed that.
