BIOBEYOND ENERGY CHALLENGE PHOTOSYNTHESIS UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS VERIFIED 2027 EDITION
1. What is meant by the term wavelength? Select the best answer:
Distance between two peaks
2. Looking at the image to the right, which categories of light exist other than visible light? Select all
that apply:
Radio, Gamma Rays, Infrared, X-rays
3. Which particular photons do you think contribute most to photosynthesis?
Blue photons
4. What do you think is happening to the green light in the image?
It gets reflected off of the leaf and into the person's eyes
5. Knowing this, what is the relationship between the wavelength and energy of a photon? Select the
best answer below:
Shorter wavelength has higher energy
6. Which particular photons might contribute most to photosynthesis? Select all that apply:
red photons orange photons, and blue photons
7. What do you notice that they all have in common? Select the best answer:
All of the molecules have rings
8. What do you think makes purple sulfur bacteria appear to be purple or reddish like in the image?
Select the best answer:
A pigment other than bacteriochlorophyll is reflecting purple or reddish and is absorbing the other colors
we don't see
9. From the image, where do you think chlorophyll can be found in plants? Select the best answer:
Thylakoid membranes in chloroplasts
10. Which molecules are present, increasing, decreasing, or staying constant in the graph to the
right? Choose an answer for each molecule:
decreasing, increasing, decreasing, absent, increasing
11. What if you took one pebble of granite from Mount Everest? Do you think you would be able to
notice an appreciable change in the size of Mount Everest?
No noticeable change
12. What happens to the energy provided by a photon after it strikes a chlorophyll molecule in a
plant? Select all that apply:
After reaching the reaction center, energy is used to excite an electron and It gets transferred from
chlorophyll molecule to chlorophyll molecule until it reaches the reaction center
13. Which molecules are present, increasing, decreasing, or staying constant in the graph to the
right? Choose an answer for each molecule:
