  • What is the female part of a flower? What does it produce? where?
    Pistill / egg cells in the ovary
  • An important function of plants is to..
    reproduce
  • What does "scattering of seeds" means?
    Seed dispersal
  • What is "pollination" ?
    The transfer of pollen from stamen to pistill
  • What is an "Ovary" ?
    - In the pistill - produces egg cells - The place where egg cells and sperm cells are combined to produce seeds.
  • Petals
    - Colourful - Protect the part that makes seeds - Attract seeds, butterflies, birds, and other organisms.
  • What is to reproduce?
    to make more of the same kind/ produce offspring
  • What are the steps of the life cycle of a plant?
    ...
  • Meaning: Life Cycle of plant
    Includes all of the changes the plant goes through from fertilization to death.
  • What is "fertilization" ?
    Occurs when the sperm cell and the egg cell combine inside the ovary to make seeds. This happens after pollination.
  • Flowering plants and conifers reproduce by ...
    Seeds
  • What is the male part of a flower? What does it produce?
    Stamen - pollen (sperm cells)
  • What is a "Pistill" ?
    - Female part - contains an ovary
  • How can bees contribute to the process of "Pollination" ?
    They can move the pollen to the pistill when they absorb the nectar
  • Meaning: Seed dispersal
    Scattering of the seed
  • Sepals
    - green leaf part - cover and protect the flower bud
  • What happens after pollination?
    Fertilization
  • Give 2 examples of plants that reproduce by spores
    Ferns (non-flowering/ vasular) and mosses (non flowering non-vascular)
  • Which part of the flower produces pollen that contains sperm cells?
    stamen
  • Wha do plants need to germinate?
    Water/ Oxygen / temperature
  • Germinate / Germination
    Grow
  • What is "Nectar" ?
    a liquid that flowers produce and bees love.
  • What is "Germinate / Germination) ?
    Sereds grow to a plant
  • Non-flowering plants reproduce by ...
    Spores
  • Give example of 2 plants that reproduce by seeds.
    Daffodills (flowering) / Conifers (cones)
  • What do we call the process of the scattering of the seed?
    Seed disperal
  • What is a "stamen" ?
    -The male part - surround the pistill - produce pollen that contains sperm cells.
  • Which part of the flower is the ovary in?
    pistill
  • What does "Seed dispersal" mean?
    Scattering of seeds (plant/ animals/ wind..)
