TRICHOMES:
-Trichomes are HAIRS found on
fast plants.
-They are found above the
cotyledons and on the stalk of
the true leaves.
-We are going to COUNT the #
of trichomes on the LOWEST
Cotyledons
true leaf.

RECORD OBSERVATIONS
-quantitative – data table
# plants [total]
# each color stem
# each color leaf
# true leaves/cotyledons on a

YEAST POPULATION
COLLECT a sample of yeast population:
-put 1 drop of yeast mixture on a slide
-add 1 drop methylene blue to drop of yeast
LOCATE yeast cells under microscope:
-find under low power—focus
-turn to medium power—focus
DRAW what your cells look like in your journal
-show the groupings/clusters of cells
-estimate #s in a single view
RECORD a picture if you can get a good shot
