S: Inside a Lily Flower: A Flower Dissection By: Judy Ketron

BC: You have now dissected a lily flower.

FC: Inside a LilyFlower: A Flower Dissection By Mrs. Ketron

1: Dissect 1. Methodically cut up (a body, part, or plant) in order to study its internal parts. 2. Analyze (something) in minute detail.

2: Observe 1. to watch/look at something closely using all your senses 2. to study something in detail.

3: Observation 1. a record of detailed information about an object that you describe using your five senses. 2. a record of detailed information about an object that is described using numbers (counts, measurements)

4: Flowers differ in such features as size, shape, and color but ...

5: all flowers contain... | the same basic parts.

6: Study the parts of a flower diagram

7: Study your lily closely. What do you observe?

8: What parts or structures do you see?

9: Sketch your lily to show detail.

10: The Stem holds the flower away from the ground so insects can pollinate the flower. It also carries water from the root to the flower.

11: The Pedicel The stem connecting each flower to the main axis are called pedicels.

12: The Sepals The sepals are small leaf-like parts of a flower that protect the bud before it opens. In a lily the(the outermost layer) has been mutated so that it looks like petals to attract insects because of its colours.

13: How many sepals do you see? Carefully remove the sepals and place them on the outermost concentric circle.

14: The Petals The petals of a flower are usually colorfulto attract bees, butterflies, and other pollinators. Many petals have a line guiding the insects toward the nectar source.

15: How many petals do you see? Carefully remove the petals and place the petals on the 2nd concentric circle.

16: A lily

17: Flowers have both male and female reproductive parts. The male reproductive part is the stamen. The female reproductive part is the pistil.

18: The Stamen The stamen are made up of two parts - the filament and the anther. The stamen is the the male reproductive part of the flower that produces pollen.

19: The Filament The filament is a threadlike structure that supports the anther that holds the pollen.

20: The Anther Anthers sit atop the filament as part of the stamen. It is a saclike structure where pollen is produced.

21: How many anthers do you see on your flower? | Pollen Pollen are the male reproductive cells. Can you see the tiny pollen grains on the anther?

22: Stamen How many stamen do you see circling around the pistil on your flower?

23: Do you notice the symmetry of the stamen? | Stamen Carefully remove the stamen and place them on the 3rd circle on your flower mat.

24: The Pistil The pistil is the female reproductive part of the flower. It is made up of the ovule, the style, and the stigma.

25: This is a pistil that has been dissected from flower. The stigma is located at the top of the pistil.

26: The Stigma The sticky stigma is located at the top of the pistil and is designed to collect pollen grains when insect pollinators or wind blows the grains onto it. This is site of pollination.

27: The stigma is located in the center of the flower with the stamen circling around the structure. | Can you see the tiny pollen grains on the stigma?

28: The Style The style becomes the pathway for pollen tubes to grow from pollen grains adhering to the stigma. The style is located between the stigma and ovary.

29: The Ovary The ovary is located at the base of the pistil. Inside are the ovules which is the site of flower fertization.

30: The Pistil and Stamen are the female and male reproductive structures of the flower.

31: Pistil Carefully remove the pistil from the stem and place on the innermost circle of your flower mat.

32: The Ovary The ovary is the base of a modified leaf called the carpel. The ovary wall becomes the fruit covering the seeds.

33: The Ovule The ovule becomes a seed.

34: How are Flowers Pollinated? Flowers can be pollinated in many ways such as bees, butterfies, hummingbirds, bats, and wind.

36: Self Pollination & Cross Pollination

37: In cross-pollination the pollen from one flower pollinates another flower of the same species. | In self-pollination the pollen from the same flower pollinates itself.
