Merits and Demerit of BESSEY'S system of classification

 Merits of Bessey's system of classification:

1.Although Bessey initially followed Bentham and Hooker's system of classification however did not place the  Gymnosperms in between Dicotyledons and Monocotyledons as in Bentham and Hooker's system.

2.Bessy abolished Monochlamydeae from his system and distributed the families of Monochlamydeae in Oppositifoliae of Dicotyledons.

3.Ranales, which are accepted as the primitive forms form the starting point of Bessey's system.

4.The families with superior ovary precade families with inferior ovary in this system.


Demerits of Bessey's system of classification: 

1.In this system, the monocots have been discussed prior to dicots, which is its greatest demerit.

2.Hypogyny, perigyny and epigyny have been emphasized too much in the system.

Separation of Photosynthetic Pigments by Chromatography

How you can separate leaf pigments by a process known as chromatography?  In this example I'm going to use spinach leaves so the first step is for you to obtain your plant that contains the pigments you wish to separate break up one of the leaves and de little pieces and place it in a mortar add a few drops of acetone and a little bit of sand as this helps with grinding up the leaves use the pestle mortar to grind up the leaves and to release the pigments if it helps here  you can add a few more drops of acetone but ultimately the objective is to obtain a concentrated pigment in a liquid at the bottom of the mortar. Chromatography Paper after you've done this then you need to prepare your chromatography paper now this does actually work best with thin layer chromatography paper but you can also use regular chromatography paper to prepare you're going to obtain a pencil and it is important that it's a pencil not a pen because a pen contains other pigments use the pencil
