Study Set Content:
glucose and fructose are sent to where
roots, stems, leaves, fruits, flowers and seeds
used by the plants as an energy source, which helps them to grow
glucose and fructose
glucose and fructose combined with each other to form more complex sugars like
cellulose and starch
structural material that is used in plant cell walls
cellulose
The number of bubbles formed indicate the rate of
Photosynthesis
The black or blue-black coloration indicates
the presence of starch and chlorophyll as well
procedure in the second video
1. Obtain a leaf sample with areas where chlorophyll is absent and present.
2. Boil water in beaker.
3. Subject leaf to beaker for 20 seconds.
4. Submerge leaf in boiling ethanol using water bath for 2 minutes (removal of chlorophyll).
5. Soften leaf with cold tap water
. 6. Flatten the leaf on the tile.
7. Drop enough iodine solution to the whole leaf
8. Indicate areas with or without starch.
Droplets of water will be present due to
Transpiration
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
Photosynthesis
Photosynthesis in plants, generally involves the green pigment
cholorophyll
Photosynthesis generates oxygen as a
byproduct
use light energy to make two molecules needed for the next stage of photosynthesis
Light dependent reactions
energy storage molecule
ATP
and the reduced electron carrier
NADPH
In plants, the light reactions take place in the
thylakoid membrane
light-independent reactions in photosynthesis that take place in three key steps.
Calvin Cycle
Calvin cycle and light-dependent reactions relationship
not directly dependent, but indirectly dependent since the products of light-dependent reactions are needed for Calvin Cycle to happen
the first stage of the Calvin cycle, light independent reactions are initiated;
Fixation
CO2 is fixed from an inorganic
to an organic molecule
In the second stage, ATP and NADPH are used to reduce 3-PGA into
G3P
