Cards (147)

  • Biology of heredity
    Genetics
  • Scientists and researchers who study hereditary processes
    Geneticists
  • Advance in genetics research have occured since
    The mid twentieth century
  • The history of genetics study spans a period of about
    150 years
  • some of the earliest ideas about reproduction.... were the particulate theories developed in
    Ancient Greece during the 4th Century BC
  • what was one of the reason these theories were innacurate?
    they relied on observations unaided by the microscope
  • the use or investigation with the microscope
    microscopy
  • first observed cells through a microscope
    robert hooke
  • father of biology
    Aristotle
  • noted that individuals sometimes resemble remote ancestors more closely than their immediate parents
    Aristotle
  • the offspring is gradually generated from an undifferentiated mass by the addition of parts
    Epigenesist
  • Announced the theory of natural selection
    charles darwin and alfred russel wallace
  • book made by charles darwin
    On the origin of species by means of natural selection
  • examined a cork
    robert hooke
  • what did hooke see in a cork
    honeycomb pattern of rectangles that reminded him of cells
  • hookes observations prompted scientists to
    speculate that living tissue as well as nonliving tissue was composed of cells
  • performed microscopic studies and concluded in 1824 that plant and animal tissue is composed of cells
    Rene dutrochet
  • All plants were structured of cells
    Matthias Jakob Schleiden
  • suggested that animals were also composed of cellss
    Theodor Schwann
  • all living things are composed of cells,, the simplest forms of life that can exist independently
    Matthias Jakob Schleiden and Theodor Schwann
  • Cells can reproduce themselves
    Rudolf Virchow
  • father of biology
    aristotle
  • what was the series of theories that was published by charles darwin?
    on the origins of species by means of natural selection (1859)
  • what did hooke examined using microscope?
    cork
  • who concluded that both plant and anima tissue was composed of cells?
    Rene Dutrochet
  • presented his theory that all plants were constructed of cells
    Matthias jakob schleiden
  • suggested that animals were also composed of ccells
    Theodor Schwann
  • who launched the theories of biogenesis when he posited in 1858 that cells reproduce themselves
    Rudolf Virchow
  • The formation, structure, and function of cells
    Cytology
  • what enabled scientists to identify parts of the cell
    cytology
  • directs all cellular activites by controlling the synthesis of proteins
    nucleus
  • mitochondria
    organelles that catalyze reactions that produce energy for the cell
  • his contributions to genetics was evolutionary theory known as the gerplasm theory of heredity
    August Weissmann
  • Builds darwin's idea that specific inherited characteristics are passed from one generation to the next
    Germplasm theory of heredity by August Weissmann
  • weissmann asserted that the genettic code for each organism was contained in its
    germ cells
  • produces cells that are genetically identical to the parent cells
    mitosis
  • cell division that reduces the amount of genetic material in the gametes by one half
    Reduction division (meiosis)
  • the first scientist to successfully refute the members of the sscientific community who believed that physical characteristics acquired through environmental exposure were passed from generation to generation
    August Weissmann
  • A farmers son becomes the father of genettics
    Gregor Mendel
  • The scientific study of plants
    botany
