  1. Fertilization occurs when ______lands on a sticky pistil top.
  2. This process is called ______.
  3. The ______become the seed and the enlarged ______becomes the fruit.
  4. Pollen is made by the ______.
  5. The male reproductive organ of the plant is the ______.

  7. The sepals support and ______the plant.
  8. The threadlike part of the stamen is called the ______.

What is the difference between self pollination and cross pollination?

Label the Following Parts of the Flower

Fertilization:

  1. Pollen lands on sticky pistil top (pollination).
  1. One sperm nucleus fertilizes the egg. The other joins the food nucleus to make a food supply.
  1. Ovule becomes a seed.
  1. Enlarged Ovary becomes the fruit.
  1. Seed = embryo + food supply

Label the following as either a trait of a:

Gymnosperm (G) or Angiosperm (A)

Pollination: Transfer of male pollen to female pistil / Needle Shaped leaves
Flowering Plant / Conifers
Produce seeds on cones / Fertilization: Sperm meets egg to produce an embryo
Keep leaves all year (evergreens) / “Naked Seeds”
Plants that produce seeds in flowers / Fruit: Enlarged ovary containing seeds
