  4. Writing
    • Rules To Avoid Food Poisoning:
    • Practice good hygiene
    • Prepare food w/ utensils
    • Keep foods above 140 or below 40 F
    • Dont cross contaminate foods
    • Keep pets out of kitchen
    • Red Wood Tree
    • 1 During the fall the ovulate and staminate cones develop
    • 2 Durning the next spring the pollem is transfered from the staminete cone to the ovulate cone
    • 3 One year later fertilization takes place. It is now know as a "one year cone
    • 4 Durning the fall the cone opens releasing its seeds. It is now know as the two year cone.
    • The seeds germinate and become a seedling with 6 to 10 catyledons
    • Ferns Growth
    • 1 A fern sporangium releases its spores
    • 2 A fern spore germinates and becomes the fern prothallus which produces the archegonia and antheridia
    • 3 The sperm swim from the antheridia to the archegonia and fertilizes an egg there
    • 4 This fertilized egg develops into the fern frond which produces more spores
    • Plant Growth
    • 1 The moss capsule releases its spores
    • 2 The moss spores germinate and become protonema
    • 3 The protonema produces both gamete producing structures: the archegonia and the antheridia
    • 4 The sperm swims from the antheridia to the archegonia and fertilizes an egg there
    • 5 The fertilized egg developes into the stalk and capsule which later disaperses its spores
    • Fungal Structures: Hyphae, Spores, Sporangium, Sporangiophores, Hyphae
    • Reproductive Structures: Progametes, Gametes, Zygotes, Zygospore
