  1. Discuss what occurs when photons of light energy are absorbed by pigment molecules.
  2. What are the differences between C4 and CAM plants?

Solutions

Expert Solution

The pigment molecules present are chlorophyll a , chlorophyll b , chlorophyll c

These molecules absorb the photons of the light energy and helps in 3 functions ( absorption , transmission , reflection)

The chlorophyll absorbs the specific amount of the energy and transmits the electron from the ground level to excited state level

Remaining energy from photos which are high or low are reflected by the pigment molecules ( They are not absorbed)

--------> C4 plants are mesophytic plants whereas CAM plants are xerophytic plants

---------> kranz anatomy present in C4 plants whereas absent in CAM plants

---------> Both bundle sheet cells and mesophyll cells seen in C4 plants but only mesophyll cells in CAM plants

----------> 12 NADPH and 18 ATP are needed to produce glucose in C4 plants whereas 12 NADPH and 39 ATP needed for glucose production in CAM plants

When you shine a light on an object, the momentum from the photons that make up that light impacts the object. For macroscopic objects, this will have no measurable effect. Describe why this is different for atomic-sized objects. Suppose you shine a very long wavelength light on one electron and a very short wavelength light on another electron. What differences will you observe? Why does shining very short wavelength photons on an electron not tell you exactly where the electron...
