What to know for the first Lab Practical


"What do we need to know for the practical?"  To avoid confusion, use the below to guide your studying.

You should be able to:
-- Identify different vegetative parts of a plant and tell their functions--roots, stems, leaves, shoots, etc., and their modifications (tuber, corm, rhizome, etc.)

-- List or identify vegetative and reproductive features which distinguish monocots from dicots

-- Identify different reproductive parts of a plant and tell their functions.  Know the terms that go with them (carpel, locule, ovule, etc.)

-- Interpret a given  flower or fruit with regard to ovary position, number of carpels, placentation type, symmetry, pollination type

-- Identify the different fruit types presented in lab.  Know the characteristics of each fruit type so that you can assign a fruit type to any given fruit sample.  (e.g., if it's fleshy and indehiscent and has one seed surrounded by a stony inner layer, it must be a drupe.)

-- Recognize material belonging to the eight major families from the Major Families lab and know the special floral or vegetative features of each one.

--Assign a sample to the correct subfamily of the Rosaceae based on floral structure or fruit type

-- Determine which head type is represented by a given sample of Asteraceae and identify the parts of the head

-- Assign Lamiaceae, Apiaceae, Solanaceae, and Liliaceae herb and spice samples to the appropriate family or list examples by common name if given the family.

-- Identify the plants we studied which are toxic or edible only when cooked.


-- Identify the various crops presented in lab, giving their common name, family, genus, and specific epithet, their monocot/dicot placement, part used, and area of origin.
    The best way to do this is to make flash cards with the image of the plant on one side and the information on the other.  Group by family and study.  Group by plant part and study.  Group by area of origin and study.  Connections will become clear.  E.g.  Which crops are in the same genus?  The same species?  Which crops have multiple edible or useful parts?   It can help to learn which ones are monocots or gymnosperms and assume that everything else is a dicot.  Learn which plants are New World in Origin and assume that everything else is from the Old World.

Exceptions:
1.  If you only saw the plant as a can or box or other packaged product and not the whole structure, you need to know the common name only: examples: Acerola, Ackee, Calaloo, Galangal, Hibiscus, Longan, Picaya (palm inflorescence), Rambutan, Toddy Palm

2.  For these less common plants, you need only know common name, family, structure/fruit type and origin, not genus and specific epithet:  Brazil Nut,  European Chestnut, Gobo Root, Goji Berry, Guava, Kang-kung/Water Spinach, Long Squash, Lotus "Root", Macadamia Nut, Malanga,  Pitaya/Dragonfruit, Water Chestnut

You will not need to:
--know anything that was on a handout but which we were unable to find for lab.

--distinguish the different types of apples, pears, hot peppers, tomatoes, potatoes, or lettuce.

The practical will be arranged as twenty stations, each with one to three questions, for a total of 50 questions.  There will be a bonus station worth 3 points.  You will have a timed 1.5 minutes per station, with 5 minutes at the end to go back and look at any station you need to, so long as there is only one person at any given station.  Questions will be short answer, not multiple choice.  There will not be a word bank.  With regard to spelling, your answer has to start with the right letter and have most of the right letters in the right order and sound correct if we say it out loud.  Family names should end appropriately.  Each section will have a different practical.
