Question

biology 101

Answer 1

First of all the plural of spectrum is spectra.

Chlorophyll a and b which absorb in the red and blue regions of the VISIBLE spectrum. This means that of the visible colors, the red and blue ones are removed, leaving mostly green, which is why most leaves appear green to our eye.

Answer 2

blue and red

Answer 3

The two photosystems in a leaf are P680 and P700. That means that these two photosystems absorb light of wavelength 680 and 700nm. However, that is not the only light used. From physics, we know that the leaf appears green because the leaf reflects the color green. This means that the other colors, i.e. red, blue, orange, are all absorbed by the leaf.
