Shady habitats proportionally more abundant far-red light, which is absorbed primarily by photosystem I (PSI) at P700nm, for better balance the flow of energy through PSII and PSI so, what will be the changes appear to enhance light absorption and energy transfer in shady environments?
a.) some shade plants is
to produce a higher ratio of PSII to PSI reaction centers, compared with that
found in sun plants
b.) photosystem I (PSI)
for enhancing light absorption and energy transfer in shady plants increases
their reduction potential
c.) some shade plants add
more antenna chlorophyll to PSII to increase absorption by this photosystem
d.) photosystem I (PSI)
for enhancing light absorption and energy transfer in shady plants decreases
their reduction potential
Which of the following above combination is TRUE?
