In the older lab, a spectrophotometer measured how fast became reduced. (it replaced the role of nadp in the plant). as it becomes reduced it changes from to

The first blank can be correctly filled up with DCPIP (2,6-Dichlorophenolindophenol).

The second and third blanks can be correctly filled up with blue and colorless respectively.

DCPIP is blue in color and used as a redox dye.

It shows maximum absorption at 600nm and become colorless when it is reduced.

With the help of spectrophotometer, it is used to determine the rate of photosynthesis.  

It is reduced in place of NADP⁺ when placed in a photosynthetic system.

As it gets reduced it becomes colorless and allows more transmittance of light which is calculated with the help of spectrophotometer.

phylogenetic tree is the tree of life or evolution tree. it shows the different branches of evolution. the sequence goes like tissues - coelom - backbone - endoskeleton - segmentation

protist eukaryotes that are not plants, animals, or fungi ("misfits")
