Flower structure and reproduction?

2. The flower attaches to what part of the plant?

3. Why are flowers brightly colored?

4. Name two mammals that might pollinate a plant.

5. If the petals of a flower are reduced or absent, how is the plant pollinated?

6. The female reproductive structures are called the:

7. Name the three parts of the pistil:

8. Where are the ovules stored?

9. Name the two parts of the stamen:

10. Describe sexual reproduction in plants.

11. The ovary develops into what structure?

12. Define fruit.

13. Some flowers are not brightly colored at all, but have a very pungent odor that smells like rotting meat. How do you think these flowers are pollinated?

14. In many flowers, the pistils and stamens reach maturity at different times. Considering what you know about pollination, why would this be an advantage to the plant?

Flower structure and reproduction?

3To attract animals; insects birds,spiders

4Herbivores like woodchuck,chipmonk, deer

5 usually wind



8in the ovary


10. The details get a bit complex. Overall; Pollination; pollen carried from anther to stigma; sperm nuclei germinates out of pollen grain, goes down style into ovule and fertilizes egg nuclei ("double fertilization" occurs), Seed develops from ovule and fruit develops from ovary. Next seed is dispersed.

11fruit (the ovule turns into a seed)

12a ripened ovary

13scavengers (the common housefly would like these flowers)

14prevent self pollination

p.s. I feel a little guilty doing your homework for you (:
