What major deficiency does dye N719 have when compared with chlorophyll (most common photoactive pigments found in plants)?
How would this deficiency might be overcome?
Chlorophyll is the most abundant pigment that commonly found in plants, bacteria algae ,and bryophytes , plays a vital role in photosynthesis .chlorophylls are natural pigments and therefore safe environmental friendly easily available and cheap. Chlorophyll has been experimented to function as a photosensitizer in dye-sensitized solar cells. A counter electrode and an electrolyte containing a redox mediator . The dye absorbs light ,which is transformed into electricity .Chlorophyll can be extracted from the leaves of pomegranate ,papaya, spinach.
N719 dye is the ammonium salt of n3 dye with changes to increase cell voltage and solubility in polar solvents comparing with n3 dye ,n719 is also one of the most common high performance dyes that are developed foe DSSC solar cells.n719 dye is an amphiphilic and increased electrostatic binding ontoTIO2 surface at lower pH values. Its increases oxidation potential leading to deeper HOMO energy levels and enhanced stability.
To prepare co-adsorbents can over come the deficiency of n719 absorption in the low wavelength region of the visible spectrum ,offset competitive visible light absorption.

why plants have two types of chlorophyll instead of just one. How does this benefit them? What would you expect concerning the rate of photosynthesis for a plant that had only one type of chlorophyll?

-Give a brief background on the role of pigments in photosythensis. -state your hypothesis. -finish with stating the rationale for your hypothesis (how did you arrive at these hypothesis?) this is an introduction piece, so it doesn't need the results to write the papee. introduction sections set up the background, purpose, rationale, and hypothesis for a study. Biod 20 PHOTOSYNTHESIS Background Plants harness the energy of the sun through a process called photosynthesis. The leaf is the plant organ that...
1. 2. 3. The scenerios are given for each questions and the question have to be answered based on those scenerios. Scenario #1: You genetically modify a group of Brassica rapa, plants so that they have increased carotenold levels. However, an unanticipated side effect of the experiment is that phosphofructokinase function is impaired to only 50% of normal activity, How would the photosynthetic activity be affected in these plants? a. Photosynthesis would increase when plants are exposed to light at...

1) Compare and contrast embryo development in from fertilization to mature seed. 2) Fabian performed a mutant screen and found a plant the was extra droopy when compared to wildtype. Upon further analysis, he found that the plant’s stomata didn’t open very well. What kind of gene/protein might have been mutated in this plant? 3) How does plant biotechnology enable one to overcome genetic barriers between distant species (different genera or even families)
