Three pigment absorption spectra from a model green leaf are shown. Which deduction is supported? A. Red illumination near 666 nm can supply energy for oxygen-producing photosynthesis B. The leaf must absorb every wavelength equally C. Green illumination near…
A green leaf receives only a narrow band of blue light centred near 445 nm. Which plot could show the photosynthesis supported by the wavelengths actually supplied? A. Plot A B. Plot B C. Plot C D. Plot D
Which conclusion is supported by these absorption spectra? A. R absorbs more strongly than G near 540 nm B. G absorbs equally at all wavelengths C. R has no absorption at 480 nm D. The graph directly measures photosynthetic oxygen production
