5 Matching questions

  1. Prophase II
  2. Ovaries
  3. Cytokinesis
  4. Sexual Reproduction
  5. Fertilization Membrane
  1. a - happens at the end of telophase
    - cytoplasm divides into two daughter cells
    - in animal cells, a cleavage furrow forms, cell membrane indents along the equator of the cell and cell split
  2. b - centrioles migrate to opposite poles
    - spindle apparatus forms
  3. c - hard layer that surrounds the ovum cell membrane
    - prevents multiple fertilizations
  4. d - fusion of two gametes (specialized sex cells produced by each parent)
    - meiosis is the process where the sex cells are produced
    - mitosis preserves the diploid chromosome number while meiosis halves it
    - somatic cells undergo mitosis, gametocytes undergo meiosis
    - during fertilization, two haploid gametes fuse, restoring the diploid number
  5. e - female gonads
    - found in the abdominal cavity
    - produce eggs (ova)
    - secrete esterogen and progesterone
    - consist of thousands of follicles

5 Multiple choice questions

  1. - nuclear membrane forms around each new haploid nucleus
    - two daughter cells are formed after cytokinesis
    - by completion of meiosis II, four haploid daughter cells are produced per gametocyte
  2. where chromosomes are joined
  3. - replication of the nucleus followed by unequal cytokinesis
    - the cell membrane pinches inward to form a new cell that is smaller in size but genetically identical to the parent cell
    - can grow to an adult size
    - new cell may separate immediately from the parent or remain attached to it
    - occurs in hydra and yeast
  4. - homolgous pairs (tetrads) align at the equatorial plane
    - each pair attaches to a separate spindle fiber by its kinetochore
  5. - chromosomes condense
    - centriole pairs separate and move toward opposite poles of cell
    - spindle apparatus form
    - nuclear membrane dissolves
    - kinetochores, attached kinetochore fibers, appear at the chromosome centromere

5 True/False questions

  1. Anaphase- sister chromatids separate
    - telomeres are the last part of the chromatids to separate


  2. Meiosis II- similar to mitosis
    - not preceded by chromosomal replication


  3. Vaginal Canalwhere chromosomes are joined


  4. Binary Fission- prokaryotes' way of of cell division
    - a type of asexual reproduction
    - splits into two equal halves, each daughter cell receives a complete copy of the original chromosome


  5. Monozygotic (identical) Twins- results when two ova are released in one ovarian cycle
    - fertilized by two different sperm
    - two embryos implant in the uterine wall individually
    - each develops its own placenta, amnion and chorion
    - share characteristics in the level of siblings
