Suggest a reason why plants contain lightabsorbing pigments in addition to chlorophylls a and b.
Step by step
Solved in 2 steps
- explain which colors of light a plant with just chlorophyll a would result in the highest photsynthetic output. Why would a yellow only light scenario not be ideal for plant containing both chlorophyll a and chlorophyll b.why it is important for a plant to maximize the absorbance ability of its pigments?All plants contain chlorophyll a. In addition, many plants contain other types of chlorophylls and accessory pigments. Suppose a new agricultural technology is developed in which accessory pigments are somehow embedded or injected into crops that naturally have only chlorophyll a. Explain the food production advantage that these plants could hypothetically provide if they could utilize many of these pigments rather than just one type of chlorophyll
- This is an absorption spectrum of plant leaf extract. Why does a plant contain an accessory pigment like phycoerythrin in addition to chlorophyll? In other words, what is the benefit to the plant?Why does light reflected by the pigment chlorophyll appear green?Leaves of a healthy potted plant were coated with petroleum jelly. How will it affect the plant? State two reasons.
- Why is chlorophyll green?Why does chlorophyll appears green to the human eye?If a leaf containing the sameconcentration of chlorophyll as in the solution wasexposed to the same ultraviolet light, no fluorescencewould be seen. Propose an explanation for thedifference in fluorescence emission between thesolution and the leaf.
- Predict the effect of the herbicide dichlorophenyldimethylurea (DCMU) on a plant’s ability to perform cyclic photophosphorylation.Melvin Calvin and Andrew Benson determined the steps in the light-independent reactions of photosynthesis by exposing the green alga Chlorella to CO2 labeled with the radioisotope carbon 14. By looking at which compounds the C14 ended up in, they were able to identify all intermediates in this cyclic pathway. Why did they predict correctly that the same set of intermediates would be formed in the light reaction in land plants?Which color(s) of light does chlorophyll a reflect? a. red and blue b. green c. red d. blue
