Cells are the building blocks of all living beings. - Sometimes the cells enter a resting phase (G0) phase where the cells perform the functions like secretion, absorption. They are; meiosis 1, and meiosis 2. UNCONTROLLED CELL DIVISION-CANCER • Cancer cells do not respond to the cell's control mechanisms • Sometimes the checkpoint gene mutates and the protein no longer works. Cell division is the process by which cells produce new cells. • Cell Division PowerPoint Slides 19-29 o Use notes on printed copy • Vocabulary Worksheet o Students will work with partners to write vocabulary words, a basic definition, a trigger word, and draw a picture to help them learn the terms. There are 3 types of cell division, depending on the type of cell. It is the life period of a cell during which a cell synthesizes DNA (replication), grows & divides into 2 daughter cells. There are two different types of meiosis. The steps to cell division. Cell division is a pre-requisite for the continuity of life and forms the basis of evolution to various life forms. Meiosis- occurs during the formation of . . Key points. The two major phases of the cell cycle include mitosis (cell division), and interphase, when the cell grows and performs all of its normal functions. When DNA replication is complete, the cells divide through a process known as binary fission. 0. Mitosis is the type of cell division during which the daughter cells have the same number of chromosomes as the parent cell. E.g. Amitosis is a direct division characterized by the splitting of nucleus followed by that of cytoplasm. Eukaryotic cell division is used for _____ and _____ of cells.

Cell Division in Sexual Reproduction: Meiosis • Meiosis is the mechanism by which eukaryotic cells produce mature sex cells or gametes • Meiosis produces four haploid cells (gametes) • Meiosis involves partition of both cytoplasmic and nuclear structures • Meiosis consists of Meiosis I and Meiosis II. Mitosis is a somatic cell division which takes place in vegetative cells.
