19 January Science 7 The anatomy of a few Nightshade fruits (tomato, capsicum, aubergine, and more?)

  1. Review DSN entry from previous class. (blogpost from previous class: http://rfrazier.msblogs.aes.ac.in/2018/01/16/4417/ )
  2. Read blogpost for today.
  3. Prepare DSN entry for today.
  4. Turn in PIP proposal.
  5. Finish pic.collage of lily flower dissection. Include your names. Send file to mpeter@aes.ac.in
  6. Traditionally scientists grouped plants based on the anatomy of flowers and fruits. This system of classification began with a Swedish scientists, Carl Linneaus, http://www.ucmp.berkeley.edu/history/linnaeus.html
  7. With the discovery of DNA and improvements in DNA related technology, scientists are relying more and more on DNA comparisons to put plants into groups.
  8. Here is one of the latest efforts to classify plants: Giant poster: https://drive.google.com/file/d/1jAQRdabRvWQ-xwkaiVcngfHDkA0dfdaB/view?usp=sharing and explanation of poster: Global-Flora-Vol-1
  9. Look at the tomato vine, flower, and fruit.

10. Use this website to help you carefully dissect and document the anatomy of a tomato 11. http://www-plb.ucdavis.edu/labs/rost/tomato/Reproductive/anat.html.

12. Take pictures, make sketches, count and measure. Make a pic.collage. Plant the seeds.

13. Dissect and document the anatomy of the peppers (bell and chili). 

 

 

 

 

 

14. Dissect and document the anatomy of the aubergine (eggplant; brinjal)

15. See the fruit from the datura species.

16. Compare your observations of the different fruits. Why do you think scientists would group all the plants (whose fruits you have examined) in the same plant family? Nightshade https://en.wikipedia.org/wiki/Solanaceae

17. If there is time, example some of the other flowers.

18. If there is time, work on your partner tree project.

19. Take a look at A Confusion of Names from Botany: A Booming History: https://www.youtube.com/watch?v=cVDpdmlpZKw

20. See the notes on the board: Bring in plant material to try to propagate–seeds (Wild, from fresh fruits you eat, from dried whole seeds, like beans and corn or maize (try popcorn). For vegetative propagation, try stems, underground parts (potato, sweet potato, ginger, turmeric), leaves. Look in parks, gardens, markets, wild lands. Do this for Sci 7 AND think about possible PIP project ideas (a documented photo gallery, a project to observe and document growth, development, reproduction, a collection (seeds and fruit)–for example, bean family tree fruits and seeds found in Delhi, a photo collection of the flower diversity seen in Delhi–both horticultural and native/wild).

21. Remember the important idea highlighted by Darwin, “More offspring are produced than survive.”
