Cells Your body is made of between 10 to 100 trillion cells About one thousandth of them die every day.
Where do new cells come from? Cells are made by a process called mitosis. Cells reproduce by making exact copies of themselves to replace the dead cell.
Mitosis Interphase Prophase Metaphase Anaphase Telophase
Interphase Period of growth & development Hereditary information (DNA) copied (replicated / duplicated)
Prophase DNA begins to shorten & thicken – Now called chromatids / chromosomes Centromeres form Nuclear membrane breaks apart Spindle fibers form
Metaphase Chromatids / chromosomes line up Centromere attaches to spindle fibers
Anaphase Centromeres divide Spindle fibers shorten Chromatid pairs separate move to ends of cell Chromatids are now called – Each ½ of the pair is now called a chromosome
Telophase Spindle fibers disappear Chromosomes uncoil Nuclear membrane forms Cell divides (cytokinesis)
Interphase Prophase Metaphase Anaphase Telophase Interphase

Mitosis - Cell Division. Living organisms have life cycles. Life cycles begin with organism’s formation, followed by growth and development and end in.
Organisms reproduce like offspring. There are two types of reproduction: ASEXUAL REPRODUCTION - producing offspring from only 1 parent offspring look.
The Cell Cycle & Cell Division. The Cell Cycle
Cells divide during mitosis and cytokinesis. Cells that make up the “body” of an organism 2.
Cellular Reproduction. Mitosi s I – Interphase: Period between division DNA molecules duplicate Single strands (chromatin threads) X shaped chromosomes.
CHAPTER 11 REVIEW Ms. Parekh. WHAT IS THE CELL CYCLE? A cycle of growth, development, and division What are the two main phases of the cell cycle? Interphase.
Warm Up-Cell Division K-W-L: Cell Division. Warm Up-Cell Cycle 1.Write “The Cell Cycle” 2.List the four phases of mitosis and their key word.
MITOSIS. Animated Cycle
Mitosis - Cell division
The cell cycle and mitosis. Cells constantly reproduce exact duplicates of themselves. Why? Replacement Repair Growth.
The Cell Cycle & Cell Division (Eukaryotic cells).
Review What is the cell cycle? What are the two stages of the cell cycle? Why do cells need to divide?
Mitosis Divide and conquer. How do cells multiply? Cell cycle – process where: DNA contained in chromosomes duplicates Parent cell divides each new cell.
Cell Reproduction Mitosis & Meiosis.
Cell Division Review. What the four major stages of the cell cycle? Which stages make up interphase?
Mitosis and Meiosis Higher Biology Mitosis and Meiosis Mitosis: -division of somatic (body) cells Meiosis -division of gametes (reproductive cells)
CELL DIVISION. When cell divides forming 2 new cells Prokaryotic cells Called Binary Fission Split into 2 parts Eukaryotic cells Called Mitosis.
Cell Division Mitosis and Cytokinesis. Cell Reproduction Interphase – Cell growth, DNA synthesis, Growth and Preparation Mitosis (Division) – dividing.
CELL CYCLE How many cells do we begin with? 2 How do we get more?
Mitosis (Cell Division) MITOSIS. Vocab 1.Cell Cycle: the life cycle of a eukaryotic cell, consisting of growth and division 2.Chromatin: uncoiled DNA.
Chapter 3.2 Cell Division Life Science. What causes organisms to grow?? Many organisms start as one cell…what happens to these cells? –Cells divide!!
Cell Cycle. Why do cells divide? Growth --by adding cells, not having them get bigger --cells are not efficient for exchanging materials if they are too.
Mitosis By: Tim Goudemont. What is Mitosis? Mitosis is a process where a single cell divides into two identical daughter cells (cell division). But the.
Cell Division Mitosis. Produces 2 cells – called daughter cells – from one parent cell Daughter cells are identical to each another and to the original.
Cell Reproduction Mitosis. Why is Cell Division Important? In humans cell division is needed for: 1. Repair 2. Growth 3. Replacement like skin and bone.
Cell Division pg. 67 Cell life cycle - changes a cell goes through from when formed to division 1.Interphase - cell grows, metabolic activities 2.Cell.
The cell cycle Mitosis is only one section of the life cycle of a cell. Interphase is the main part of the cell cycle. This is where DNA is replicated.
GENETICS. Mitosis and the Cell Cycle Cell reproduction.
The Cell Cycle Cell Division Onion Cells Cell Division A cell must divide to: Grow Reproduce Repair damaged tissues.
Cell Reproduction Why do Cells Divide? Section 5-1, 5-2.
Do now!! What two (2) reasons do you think cells divide?
Mitosis Asexual cell division!! Begins in the nucleus of a cell.
Cell Cycle IPMATC. Cell Cycle 3 Parts: – Interphase – Mitosis Prophase Metaphase Anaphase Telophase – Cytokinesis.
Mitosis and the Cell Cycle Cell reproduction. Todays Objectives The student will be able to identify the phases of the cell cycle and mitotic stages by.
Cell Division. DNA Replication and Cell Division DNA must replicate so that during cell division, the new cells formed each receive a complete set of.
Mitosis Flashcards. Interphase Draw: Label: – Plasma membrane – Nucleus – DNA Interphase is not part of mitosis This is when the cell is doing its “everyday”
Unit IV: Can You Divide?. Cell Reproduction All organisms REPRODUCE. Why? –This allows for growth, development and the survival of the species.
What do they do? Stages What’s Going on? What is It?
MITOSIS. Mitosis and the Cell Cycle Sexual reproduction – combining genetic info from 2 organisms of the same species to create offspring Asexual reproduction.
Token Grab. What is the longest part of the cell cycle? Interphase.
10-2 Cell division. 2 phases of cell division Mitosis: division of the cell nucleus, including DNA replication. Mitosis: division of the cell nucleus,
Mitosis and the Cell Cycle Division of the nucleus and the nuclear material (DNA), as well as the cell.
THE CELL CYCLE— Interphase, Mitosis & Cytokinesis.
Cell Reproduction Chapter 4. Cell Growth and Division Chapter 4-1 Cells undergo division to: Increase in number Repair worn out cells Replace cells that.
THE CELL CYCLE. Producing new BODY cells allows you to: 1. Grow 2. Replace dead cells Ex: Stomach so acidic that cells lining must be replaced every few.
Cell Division Mitosis. Chromosomes Eukaryotes Found in the nucleus Contain most of the genes Made up of two sister chromatids, joined by a centromere.
The Cell Cycle Making new cells for growth and replacing old dying cells.
The Cell Cycle & Cell Division. The Cell Cycle Cycle.
Cell Cycle The repeating set of events in the life of a cell. The repeating set of events in the life of a cell. Includes Includes Interphase Interphase.
