Plant sensory system

The plant sensory system is a sophisticated system that responds to environmental stimuli such as light,temperature, gravity, and touch. Research predicts that plant hormones and signaling mechanisms areresponsible for this regulation system in plants.

Question

2. By what process does the carbon dioxide in the phenol red move into the plant
exposed to light?
3.
During which photosynthetic process does the plant in the light use the CO₂ that it
removed from the phenol red solution?
F. LOCATION OF STORED SUGARS (STARCH) IN VARIEGATED LEAVES
Variegated leaves are leaves whose pigments are not evenly distributed in all cells.
The cells of portions of the leaf which appear clear or white have no photosynthetic
pigments. Those cells in the colored portions of the leaf contain chlorophyll and one
or more of the accessory pigments. These pigmented cells are the site of photosyn-
thesis in variegated leaves.
a.
Recall that some of the sugars produced in photosynthesis are stored as starch. Using
the technique of leaf clearing and selective staining, you will determine whether starch
is stored in the pigmented or non-pigmented portions of a variegated leaf.
Procedure
Your instructor will clear a leaf by boiling it in ethanol to remove the pigments.
After the leaf is placed in iodine, you will see a color change in regions where starch is
stored. Compare a fresh leaf with a leaf having the same variegation pattern which has
been cleared and stained. Answer the questions below.
