17 January Flowers–a starting point for Growth, Development, Reproduction–and–Biodiversity (also PIP proposal and Partner Tree observations and research)

  1. Review DSN entry from last class.
  2. Read today’s blogpost. Prepare your mind for the class.
  3. Open a new document for your DSN entry for the class.

A. How is your PIP proposal coming? Turn in a paper copy for the next class. Be prepared for feedback.

B. How is your partner tree research coming? See previous blogpost to test your knowledge and the completeness of your records.

C. Conduct the flower dissection and create a display of photographs and sketches with the following partner:

Flower dissection:

Groups: Be sure to up date your partner list–

Tomas Chihaya; Boris YeonWoo; Denzel HeeJun; Anton Avanka; JaeHun Michal; Dowoo Pauline; Bailey Yaroslav

Liam Reyha; Merrick Ananya; YuBin Marvin; JaeJun Sophie; Max Hangyeol; Jaeha Halen; Gabi Hyunjin; Sulaimaan JiWoo; YuMin David

  • Review the websites on parts of flowers and forms of flowers below.
  • Flowers are reproductive structures of a large group of plants–the flowering plants.
  • Examining the flowers will bring into view the major ideas of our topic this semester: Growth, Development, Reproduction–And when we look at the variation of “kinds”–Biodiversity.
  • There is background knowledge that will help you begin to make sense of the structures and functions of flowers. (For example, inheritance, genetics, chromosomes, genes, DNA, pollen, pollination, pollinator, nectar.)

Systematically record and dissect the flower(s) you are provided. 

Take a flower apart. Examining each “piece.” Think of the flower as a puzzle, where each piece fits together in a certain way. Do this carefully, imagining that you could put it back together in exactly the same way you found it. Imagine what the function of each “piece” is. Check your ideas against the references linked below (websites and videos).

PLAN BEFORE YOU CUT. READ THE REST OF THE DIRECTIONS.

Be careful with the dissecting tools.

Make a display with photos and sketches. Count parts. Measure. Provide a scale. Describe shapes and structures. If you know the name, that is fine. If you do not, simply describe. Discuss the possible function of each structure. How would you guess that the flower(s) is(are) pollinated? Why?

Use pic collage (ap) to arrange your photos into a display. Send the file to mpeter@aes.ac.in who will print and laminate your poster.

Use the magiscope for a magnified view. With help, use the compound microscopes to get a more magnified view. If pollen is present, try to get a view of a pollen grain. Use the microscopes as directed. Make sketches, take photos, include labels and descriptions.

Make a note of these links. We will look at them as a class and you will need to review them (periodically) on your own or in a small group.

Notice the numbers in the pictures below!  See the 3’s and 6’s. This pattern is characteristic of monocots–the large group of flowering plants that includes grasses, palms, lilies, aroids.
