  1. Structures of a Flowering Plantpart 2 6.2.4: Summarize the basic functions of the structures of a flowering plant for defense, survival, and reproduction.

  2. Discuss 3 things about flowers using qualitative or quantitative words

  3. Essential Question ? What are some of the structures plants use for reproduction?

  4. Structures for Reproduction Parts of the flowering plant that function in reproduction include: Flowers • Flowers produce seeds. • Many flowers contain both male and female parts needed to produce new flowers.

  5. Flowers • Flower petals are often colorful or have a scent to attract insects and other animals.

Parts of a flower Pistil The female part of the flower that contains • The ovary, which contains the ovules where the egg cells are produced. • The stigma, which is the sticky top where pollen grains land. • The style, which is a stalk down which the pollen tube grows after pollination has taken place.

  8. Ovary with ovule and seeds

  13. Into what part of the flower did Arnold fall?

  14. Where did the kids land?

  15. Summary • What are some of the structures plants use for reproduction? Answer: • Flowers • Male parts produce pollen. • Female parts produce ovules. • Together they produce seeds that ensure survival of the species.

  16. Interactive Online Activity http://www.glencoe.com/sites/common_assets/science/virtual_labs/LS11/LS11.html We will start this lab together. You will complete the journal and data table and submit them for a daily grade. Finished? Fun game to play about flowers and pollinators. http://revolution.caret.cam.ac.uk/flash/flowers.swf
