  1. a.      __of meiosis and fertilization varies with species
    Timing
  2. Three main types
    • Humans and animals
    • Plants and some algae
    •                                                               i.      Most fungi and some protists, including some algae
  3.                                                               i.      Humans and animals:
    1.      __are only haploid cells
    a.      Meiosis in __cellsà __à no further cell division prior to __à __divides by __
    • Gametes
    • germ
    • gametes 
    • fertilization 
    • zygote
    • mitosis
  4.                                                               i.      Plants and some algae= __
    1.      Diploid and haploid stages that are __
    a.      Multicellular stage: __
           i.      Meiosis of __-->__
    1.      Spore doesn’t fuse with other cell; instead, it divides __--> multicellular haploid stage called __-->give rise to __by mitosisà fusion at __-->diploid zygoteà next __generation
    • alternation of generations
    • multicellular
    • sporophyte
    • sporophyte
    • haploid spores
    • mitoticallyà
    • gametophyteà
    • gametes
    • fertilizationà
    • sporophyte
  5.                                                               i.      Most fungi and some protists, including some algae
    1.      After fusion of gametes to form __, meiosis occurs without __
    a.      Meiosis produces not gametes, but __ that then divide by __and give rise to either __descendants or __ organism
    b.      Haploid organisms carries out further __, producing cells that develop into __
    2.      only diploid stage is the __
    • diploid zygote
    • a multicellular diploid offspring developing

    • haploid cells
    • mitosis
    • unicellular
    • haploid multicellular adult organism
    • mitoses
    • gametes
    • single-celled zygote
  6. True or False:

        
    Either haploid or diploid cells can divide by mitosis, depending on the type of life cycle
                                                            
    true
  7.       i.      Only diploid cells, however, undergo __because haploid cells are n and can’t be further reduced
    meiosis
