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 ___________________.
6. The female 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).
2. One sperm nucleus fertilizes the egg. The other joins the food nucleus to make a
food supply.
3. Ovule becomes a seed.
4. Enlarged Ovary becomes the fruit.
5. 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
