compounds)? Hint: polymer of glucose (energy
-Energy sequence in cells: H: see drawing on left:
the sun.

cellular
YES; H:
germinating

seeds.
5. Slides 5-6 - Light absorption, colors used by plants (why are most plants green?) Explain the following:
1. What does “roygbiv” mean, and how is it used by plants.
2. Explain the Engelmann experiment. H:
Aerobic bacteria attracted to the portions of
algae exposed to violet-blue/red.
3. Explain the types of chlorophyll. H: All plants, algae, and
cyanobacteria which photosynthesize contain chlorophyll "a;
chlorophyll "b" occurs only in "green algae" and in the plants. chlorophyll "c", and is found only in the
photosynthetic members of the Chromista as well as the dinoflagellates.
4. name the different types of plant pigments and their use in
photosynthesis. H: Carotenoids are usually red, orange, or
yellow pigments. They cannot transfer sunlight energy
directly to the photosynthetic pathway, but must pass their
absorbed energy to chlorophyll. For this reason, they are
called accessory pigments. Fucoxanthin is the brown pigment
which colors kelps and other brown algae as well as the
diatoms. Phycobilins are water-soluble pigments that occur
only in Cyanobacteria and Rhodophyta.

Student #2 (Leaf Structure and Location of Photosynthesis)
1. Slide 1 - Title page including:
1. Title of presentation - should catch
the audience’s attention
How Does Leaf Structure and Location Enhance
Photosynthesis?
2. A picture related to the topic of the presentation
3. Also include the following on this slide: your name names,
class, block, date.
2. Slide 2 - An introduction slide showing what you will be
presenting and how it is related to photosynthesis.
“In most plants, the leaves contain the most chloroplasts and are the
major sites of photosynthesis.
-include some type of graphics on this slide
3. Slide 3 - What type of organisms can perform photosynthesis
1. Provide a list and a graphic for each.
Examples of photosynthetic
organisms: Left: leaves from
higher plants flanked by colonies of photosynthetic purple bacteria
(left) and cyanobacteria (right). Far right: Volvox, a photosynthetic
protist
2. Which autotroph is biggest producer of
photosynthetic byproducts. Why?
H: On the planetary level, most photosynthesis occurs in the oceans,
because the oceans occupy the vast majority (70%) of the earth's
surface. In terms of organisms, photosynthesis occurs in autotrophes
that contain the green pigment chlorophyll. This would include the
entire plant kingdom, "half" of the Protista (the algae), & "half" the
Moneran Kingdom (the blue-green algae).. It is estimated that marine
producers “produce” between 70 and 80 percent of the oxygen in the
atmosphere. Nearly all marine producers are single celled,
photosynthetic algae.
4. Slide 4 - Structures in plants related to
photosynthesis
- Leaf, stomata, type of cells (mesophyll), chloroplast,
chloroplast
membrane, stroma, granum, thylakoid (stacks),
epidermis, cuticle
- Identify the photosynthetic processes taking place in each part, e.g., light reactions in the thylacoid
membranes, dark reaction take place in the stroma

Student #3 (converting light energy to chemical energy)
1. Slide 1 - Title page including:
1. Title of presentation - should catch the audiences attention, e.g., How is light energy converted to chemical
energy?
2. A picture related to the topic of the presentation
3. Also include the following on this slide: your
name names, class, block, date.
2. Slide 2 - An introduction slide showing what
you will be presenting and how it is related to
photosynthesis.
3. Slides 3, 4 – Explain how a plant converts light energy into chemical energy.
e.g., 1. Water is split,
providing electrons to replace
those lost by PSII
2. Electrons
boosted to a higher state and
accepted by a membrane
protein
3. Electrons are
passed down the electron
transport chain, creating a
proton gradient that fuels the
production of ATP
4.
Electrons leave photosystem I
and are accepted by another
protein
5. Electrons passed
down another ETC, which
leads
the
production of NADPH (energy carrier)
are
to
1. What is photosystems II & I (light reaction)? How do they function? How does a
concentration gradient play into this? Electron transport chain (ETC)
2. What are the products of the light reaction?
3. Describe function of the dark reactions (Calvin cycle). H: Convert CO2 to glucose using the energy
carriers, NADPH and ATP.
4. Explain how these molecules are
involved: (ATP, ADP, NADP+, NADPH)
sugars, carbon, electrons.
5. What are the products of the dark reaction?
6. Where are these items found?
7. How are the light and dark reactions linked together?
4. Slides 5 - Photosynthetic efficiency: How efficient is photosynthesis?
Only light within the wavelength range of 400 to 700 nm
(photosynthetically active radiation, PAR) can be utilized by
plants, effectively allowing only 45 % of total solar energy to be
utilized for photosynthesis.
1.
Compare photosynthesis efficiency to a car engine.
A gasoline engine might be as efficient as 25%, meaning that
75% of the energy is given up as heat.
Cellular respiration is 40% efficient with 60% of the energy going
to heat.
2. Explain how environmental factors change the efficiency.
(e.g., type of light)
The amount of light, the carbon dioxide supply, temperature,
water supply, and the availability of minerals are the most
important environmental factors
