Study Set Content:
Clear, glistening drop of sticky fluid containing digestive enzymes at the tip of each hair
Sundews
The two halves of the blade have the appearance of being hinged along the midrib, with stiff, hairlike projections along their margins
Venus flytraps
Constructed along the line of old-fashioned steel trap
Venus flytraps
Four curled but stiff hairs at one end of the trapdoor act as triggers when an insect touches one of them
Bladderworts
how many tiny trigger hairs on the inner surface of each half of a Venus flytrap
3
Submerged and floating in the shallow water along the margins of lakes and streams, have finely dissected leaves with tiny bladders
Bladderworts
the chloroplasts of mature leaves of Autumnal Changes in Leaf Color contains several group of pigments, such as
green chlorophylls and carotenoids, which include yellow carotenes and pale yellow xanthophylls
More chlorophyll than other pigments is present, and the intense green color of chlorophylls makes or hides the presence of
carotenes
What accumulate in the vacuoles of the leaf cells in the fall
Water-soluble anthocyanin and betacyanin
Anthocyanins color if slightly acidic
red
the more common of the 2 groups, are red if the cell sap is slightly acidic, blue if it is slightly alkaline and of intermediate shades if neutral.
Anthocyanins
Betacyanins color
usually red
Anthocyanins color if slightly alkaline
blue
Anthocyanins color if neutral
intermediate colors
process by which the leaves are shed
Abscission
leaves drop seasonally
Deciduous
Occurs as a result of changes that take place in an abscission zone near the base of the petiole of each leaf
Abscission
inhibit the formation of the specialized layers of cells that facilitate abscission are produced in young leaves
Hormones
As the leaf changes, hormonal changes takes place and at least how many layers of cell differentiate
2 layers
Closest to the stem, protective layer cells become coated and impregnated with what
fatty suberin
