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…
Identify the main light colour used in photosynthesis by each alga.
Deduce which alga is more suited to greater depth, giving a reason from its action spectrum.
Describe how to collect measurements for an action spectrum of an alga.
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
A student constructs an action spectrum for a photosynthetic alga. What quantity is plotted against the wavelength of incident light? A. The number of chromosomes in each cell B. The relative rate of photosynthesis C. The fraction of light absorbed by an…
Which conclusion is supported by these action spectra? A. Neither sample photosynthesizes at 530 nm B. P has a higher rate than Q at every red wavelength C. Q has the higher rate around 530–560 nm D. The results establish both rates at 800 nm
