Directions to Assemble the Flower

1. Cut out all twelve flower parts cards and the twelve flower part definition cards.
2. Matchup the flower part to the correct definition.
3. Get an answer key from Mr. Stark to make sure that you did it properly before moving on to the next step. Check your work carefully and then move on to the next step.
4. First, using the glue stick, paste down the definition for the flower part.
5. Next, tape the flower part card on top of the definition so it acts as a flap over the definition.
6. If all went as planned, you should have a flower part flap with the definition behind it in the proper location on the diagram.
7. Next, cut out all of six of the flower reproduction cards and the blank cards (1 through 6) that go with them.
8. You will have to draw a picture for each of the six steps. Use the blank cards you cut out to do this. The picture should accurately represent that specific step as explained on the reproduction cards.
9. Once you have all six steps drawn out, attach the reproduction card to the proper location using the glue stick.
10. Finally, tape the picture on top of the corresponding step so that the picture acts as a flap.

Pollen Tube

Petal

Pollen Grains

The entire female structure of a flower

The long stalk that holds up the anther

The sticky top of the pistil that attracts pollen and begins the growth of the pollen tube

The female sex gamete (egg) found within the ovary

The protective outer petals of the flower

The male sex gamete (sperm) found on the anther

The entire male structure of the flower

The structure of the stamen that holds the pollen grains

The long tube of the pistil in which the pollen tubes grow towards the ovules

The part of the pistil that turns into a fruit containing seeds

A passageway for sperm nuclei that leads from the stigma to the ovules

The part of the flower that attracts pollinators

1: Pollen is moved by animals, insects, wind, and water

2: Pollination takes place when a pollen grain contacts the stigma

3: Pollen tubes grow through the style from the stigma towards the ovules

4: Fertilization takes place - Sperm nuclei (from the pollen) travels down pollen tube to ovules

5: Fertilized ovules become seeds and flower petals fall off

6: Ovary becomes a fruit containing the fertilized seeds
