CHAPTER CHEICAL BASIS OF LIFE OUTLINE The human body is composed of chemicals. Chemistry describes the composition of substances & how chemicals react with each other. STRUCTURE OF MATTER ELEMENTS are composed of atoms‚ which are the smallest unit of element MATTER is composed of elements ATOMIC STRUCTURE • A complete atom is electrically neutral • Atom consists of elements‚ protons‚ & neutrons • Electrons are negative charge & • Neutrons are uncharged( neutral) • Atomic number is equal

CHAPTER 12- THE CELL CYCLE I. Concept 12.1- Cell division results in genetically identical daughter cells A. Overview 1) The continuity of life is based on the reproduction of cells or cell division. 2) The cell division process is an integral part of the cell cycle‚ the life of a cell from the time it is first formed from a dividing parent cell until its own division into two cells. B. Cellular Organization of the Genetic Material 1) A cell’s endowment of DNA‚ its genetic

chromosomes as somatic cells. (All of our gametes have 23 chromosomes) Eukaryotic chromosomes consist of chromatid‚ a complex of DNA and protein that condenses during cell division. Eukaryotic cell division consists of: — Mitosis‚ the division of the nucleus — Cytokinesis‚ the division of the cytoplasm Gametes and spores are produced by a variation of cell division called meiosis.

CHAPTER 13 OBJECTIVES The Basis of Heredity 1. Explain in general terms how traits are transmitted from parents to offspring. An organism’s traits and appearance are controlled by specific forms of proteins contained in DNA. When gametes are formed‚ the male and female parents pass along their DNA into their respective gametes. Fertilization fuses the gametes and combines the genetic contribution of each parent into the new offspring. 2. Distinguish between asexual and sexual reproduction

DIFFUSION= The movement of atoms or molecules from an area of higher concentration to an area of lower concentration. Atoms and small molecules can move across a cell membrane by diffusion. OSMOSIS= Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane. SELECTIVE PERMEABLE MEMBRANE=a membrane (as a cell membrane) that allows

Centrioles replicate Mitosis and Cell Division Function- To grow repair and maintain the cells in the body along with the reproduction of those cells. Results- Two identical daughter cells form from the parent cell. Phases of Mitosis Prophase- Nucleus disappears‚ chromatin forms into chromosomes. Centrioles start to move to outer poles. Spindle fibers start to form Metaphase-
