NUTS

 NUTS 

A nuts is  single celled, single seeded dry fruit with hard pericarp.

These have high protein and  fat contents besides starch ,sugar and mineral elements.

Depending upon the type of content which they contain ,nuts are divided into three categories:-

(1) Nuts with high protein content.

(2) Nuts with high carbohydrates content.

(3) Nuts with high fat content.

(I)   Nuts with high protein content:

(i)Almonds (badam) :prunus amygdalus; Fam- Rosaceae

(ii)Green almond(pista) :pistacia vera ; Fam- Anacardiaceae

(iii)Beech nuts :Fagus sylvatica ; Fam-Fagaceae

(II) Nuts with high carbohydrates  content:

 (i) Chest nut: Castanea sativa ;Fam- Fagaceae

(III) Nuts with high fat content.

(i) Coconut (nariyal):Cocas nucifera; Fam- Palmae

It is commonly known as Kalpavriksha because a number of useful products are obtained from it.

Chiefly grown in Kerala (Kerala mean land of coconut).

Nearly all parts of these nuts are used .These provide a nutritious refreshing juice. The soft kernels are scraped and eaten. The mature nuts provide copra (endosperm) which is used in various ways. Coconut oil is obtained from the copra.

Fibrous mesocarp provides coir. The dry leaves are used for temporary sheds.

(ii)Cashew nut (Kaju) : Anacardium Occidentale ;Fam- Anacardiaceae 

It is native of Brazil.

Most conspicuous product of the tree is 'false fruit' which is a swollen peduncle, known as cashew apple and is the receptacle for the true fruit.

(iv)Pine nut(Chilgoza): Pinus gerardiana ; Fam- Pinaceae 

The edible seeds are tasty , nutritious having a delicious flavor.

Separation of Photosynthetic Pigments by Chromatography

Image
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
