  • Which part of the flower will pollen stick to in order to complete pollenation?
    Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma.
  • In this photograph, where is the flower's recepticle?
    The receptacle is located between the peduncle (stem) and the pedals. The reproductive parts of the flower grow out from it.
  • Does the male or female gametophyte "live" here?
    The ovule is where you will find the female gametophyte.
  • Which structure, in this photograph, is responsible for making pollen?
    The anther makes pollen. The stamen is made of an anther which is supported by a slender fillament.
  • This pollen grain is ________________.
    Germinating. I would also accept growing a pollen tube.
  • What is the name of the cellular process that divides the number of chromosomes in a cell by half? Where does this process take place?
    Meisosis divides the number of chromosomes in a cell in half. This takes place in the anther and produces a pollen grain.
  • After looking at this diagram, can you explain where the male gametophyte develops and reaches maturity?
    The male gametophyte develops and reaches maturity in an immature anther.
  • Where is the ovary in this photograph?
    The ovary is the oval-shaped green object above the recepticle and below the style.
  • In this photograph, the bee is more than likely attracted to the flower because of the _____________ and ____________.
    The bee is attracted to the color of the pedals and the nectar the flower produces.
  • This is ________________.
    A stigma impregnated with pollen grains.
  • In this photograph, where are the flowers' sepals?
    Sepals are the outer parts of the flower (often green and leaf-like) that enclose and protect the pedals and other parts of a developing flower.
  • True or False. The filament produces pollen.
    False. The fillaments support the anthers. It is the anthers that make pollen.
  • As you can see, these are pine cones. Which one is staminate? Which one is ovulate?
    The staminate cones are smaller than the ovulet cones.
  • Where are these chemicals made in a flower?
    These carbohydrates, or simple sugars, are produced by the nectaries.
  • This is ________________. HINT! The words "pumpkin", "plant", or "vine" are NOT correct answers.
    a fruit that usee to be the ovary of a flower. Larsen will also accept "future pie" or "future Jack-O-Lantern".
  • Observe the obvules. Will they become fruit or seeds.
    Fertilized ovules will develope into seeds.
  • Plant growth is possible thanks to a cellular process called ______________.
    Mitosis or cell division.
  • What is the name of the chemical reaction that produces the chemical components of nectar?
    Photosynthesis.
  • In this photograph, which anatomical structure is considered to be the style?
    The style is the long, slender tube in between the ovary and the stigma.
  • Behold the lovely pumpkin flower. What will the ovary eventually become.
    The fruit.
  • In this photograph, which used to be the ovule and which used to be the ovary?
    When mature, the ovary is a fruit and the ovule is a seed.
  • In this photograph, where is the peduncle? What does it do?
    The peduncle is the main stem (or stalk) that supports the flower.
  • In spruce trees _____________ produce pollen.
    Staminate Cones
  • Extra Credit! Why should I care about flowers? Well, remember, there is only one reason to study science, and that is to make money. How much money does the US floral industry produce annually?
    $16 Billion - as cited from Cision PR Newswire (2018 - 2023 forecast)
