2-How are photosynthetic bacteria and chloroplastsrelated?

Solution

relationship between absorbancespectrum and the actionspectrum:

1)absorption spectrums:The absorption spectrum shows the ability of a pigment to absorb the different wavelengths of visible light. the absorption spectrum for three different pigments, each type of pigment absorbs some wavelengths better than others.

action spectrum:The action spectrum indicates the amount of photosynthesis taking place at different wavelengths of light. The rate of photosynthesis at a particular wavelength depends on the types and quantities of pigments in the plant. the shape of the action spectrum is very close to the shape of the absorption spectrum of chlorophyll, indicating that chlorophyll is the most important photosynthetic pigment. .

2)photosynthetic bacteria and chloroplasts related:

  No Bacteria are prokaryotes, meaning they have no specialized organelles enclosed by membranes. The ones that are photosynthetic simply have pigments that work similarly to chlorophyll.Cyanobacteria do not have choroplasts but they certainly do have chlorophyll. It is found in the cytoplasm, not in a membrane-bound organelle.
