PPT-Cell Division Life Science

How do little elephants grow up to be BIG elephants Why do animals shed their skin Cell Division Cell division increases the number of cells and causes manycelled organisms to grow The new cells that are formed are called . 2.5.1: Cell . Cycle: Outline the stages of the cell cycle, including . interphase. (G1, S, G2), mitosis and . cytokinesis. Cytokinesis starting. *During . its life, a cell passes through a well-ordered series of events known as the . Cell Increase and Decrease. Cell division increases the number of somatic cells. Consists of mitosis (division of the nucleus) and cytokinesis (division of the cytoplasm). Apoptosis, programmed cell death, decreases the number of cells. Chapter 8. Asexual vs. Sexual reproduction. Asexual reproduction – new organisms/cells are genetically identical to parent cells/organisms . Sexual reproduction – offspring have a combination of genes from both parents. . A Chromosome and Sister Chromatids. Key Points About Chromosome Structure. A . chromosome consists of DNA that is wrapped around proteins (. histones. ) and condensed. Each . histone. and the DNA wrapped around it make up a . Chapter 4: Animal Growth and Heredity. Vocabulary. Life cycle- the stages that a living thing passes through as it grows and changes.. Mitosis- the process by which most cells divide.. Chromosome- A threadlike structure in the nucleus, made up of DNA.. Chapter 10. Limits to Cell Size. Cells grow as the organism grows.. However cells only grow to a certain extent then divide. Why?. . - The larger the cell the more demands on its . dna. . - a large cell has more trouble moving food in and waste out. Cell Division . —. . process by which a cell divides into . 2 new cells. Why do cells need to divide? . Living things . grow. by producing . more cells. , NOT because each cell increases in size. Identify and restate what the phases of the eukaryotic cell cycle are.. Restate what happens in each stage of the cycle.. Vocabulary. Cell . cycle. Interphase. Mitosis. Cytokinesis. Cells . Live in a Cycle. CELL CYCLE. . The . sequence of events by which a cell duplicates its genome, synthesis the other constituents of the cell and eventually divides into two daughter cells. .. Phases of cell cycle :. •Interphase :. 1. Grab the chromosomes from the. parent cell . to fill in the other steps in mitosis, including . DNA replication. , . cell division. and the resulting two . daughter cells. . . 2. Answer the question below and move to the next slide.. Chapters 12, 13, 16, 17. Limits to Cell Growth. The larger a cell becomes, the more demands a cell places on its DNA. If extra copies of DNA are not made, an “information crisis” would occur. The cell also has more trouble moving nutrients and wastes across the cell membrane. : is the changes which occur in the cell during its division (mitosis) and during its rest (interphase).. OR . sequence of phases in the life cycle of the cell. 3- . Mitosis PAG 1.1. Foundations in Biology. spec. Mitosis and Cell Cycle. Learning Objectives. - Collection and presentation of data:. • Produce a root tip squash;. • Use a light microscope to produce annotated drawings of the stages of mitosis.. This theory . is . one . of the foundations . of . biology.. 2. Antonie . van. . Leeuwenhoek. The first man to witness . a . live cell . under a . microscope was Antonie . van . Leeuwenhoek, who .
