HW:

2. Identify the following parts1) 2) 3) 4) 5) 6)
Petals
Stigma
Anther
Style
Ovary
Filament

3. How does a plant reproduce?
Flower may contain both male and female reproductive parts
However, some flowers only male and others are only female

4. Stamen
Anther – makes and holds pollen
Filament – holds the anther

5. Pistil Ovary – makes and stores eggs
Style – tube that brings eggs out of the ovary
Stigma – keeps the opening to the ovary closed

7. Sticky part that collect pollen grains
What is pollination?
Transfer of pollen grains from the ANTHER to the STIGMA
Stigma
Sticky part that collect pollen grains

8. 2 types of Pollination Self-pollination Cross-pollination
transfer of pollen from anther to stigma of same flower
Cross-pollination
transfer of pollen from one plant to another

9. How does Fertilization Occur?
Pollen grain lands on STIGMA & forms a POLLEN TUBE
Results in a ZYGOTE

10. Why is pollination necessary?
Like humans, plants require POLLEN
to meet with the EGG in order to form a new offspring

11. How is pollination accomplished?
Petals visual attractant
Nectar acts as a chemical attractant
Insects
Animals
Wind

12. The mixing of both pollen and ovary results in a ????
SEED

13. Fruit
When pollen is able to fertilize an egg, the developing seed becomes a fruit.
The fruit contains many seeds that will spread if the fruit goes uneaten.

14. Germination
When fruit fall to the ground and release seeds, these seeds can burrow into soil and form a small plant
This is known as germination
The seed becomes a seedling and requires water and sunlight.

15. Gymnosperms
Seed plants that do not form flowers

16. Angiosperms
These are flowering plants
