5 Matching questions

  1. G₁ Stage (presynthetic gap)
  2. Follicles
  3. Binary Fission
  4. Fertilization Membrane
  5. Uterus
  1. a - hard layer that surrounds the ovum cell membrane
    - prevents multiple fertilizations
  2. b - site of fetal development
  3. c - intense biochemical activity and growth
    - cell doubles in size and new organelles are produced
    - passing "restriction point", where a cell is committed to continue through the rest of the cell cycle and divide
    - some cells like skeletal muscle cells and nerve cells never pass this point, and enter a nondividng phase sometimes referred to as G₀
    - 2N number of chromosomes
  4. d - multilayered sac of cells that contains, nourishes and protects and immature ovum
    - follicle cells produce estrogen
  5. e - 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 Multiple choice questions

  1. - male: testes
    - female: ovaries
  2. - external female genitalia
  3. - site of sperm deposition during intercourse
    - passageway through which a baby is expelled during childbirth
  4. - chromosomes align
  5. where chromosomes are joined

5 True/False questions

  1. Meiosis II- only occurs in the sex cells
    - meiosis I produces two intermediate daughter cells
    - meiosis II is similar to mitosis, it separates sister chromatids and results in four genetically distinct haploid gametes

          

  2. Cell Division- a process where a cell doubles its organelles and cytoplasm, replicates its DNA and then divides in two
    - unicellular organism: reproduction
    - multicellular organism: growth, development & replace old cells

          

  3. Seminal Fluid- or called autosomal cells
    - everything but the gamete
    - contain diploid number of chromosomes characteristic of its species (2N)
    - N is the number of chromosomes found in haploid cell (gamete)
    - in human, 2N = 46 and N = 23

          

  4. Interphase- spindle apparatus disappears
    - new nuclear membrane forms around each set of chromosomes
    - nucleoli reappears
    - chromosomes uncoil
    - cytokinesis occurs

          

  5. Anaphase- disjunction: homologous pairs separate and are pulled to opposite poles of the cell
    - distribution of homologous chromosomes to intermediate daughter cells are random
