Answer:
The characteristics of Division of Algae is
1)Chlorophyceae is also known as Green Algae.
it's major pigment is chlorophyll-a,b.
it's stored food in form of starch.
its cell wall is made up of Cellulose.
Its found in Freshwater, Brackish water and salt water.
2) Phaeophyceae is also known as brown algae.
it's major pigment is chlorophyll-a,c fucoxanthin.
it's store food in form of Mannitol and Laminarin.
cell wall is made up of cellulose and algin.
it's found in freshwater brackish water and salt water
3) Rhodophyceae is also known as red algae.
Its major pigment is chlorophyll-a,d phycoerythrin .
It's stored food in form of Floridean .
it's cell wall is made up of cellulose pectin and poly sulphate Easter.
mostly salt water fresh and brackish water.
DNA
found in chromosomes of the nucleus.
double stranded structure two strands coiled spirally in opposite direction.
the sugar is deoxyribose.
Purines and Pyrimidines occurin equal proportion.
DNA is hereditary material.
control structure metabolism differentiation and inheritance.
long molecule with high molecular weight.
genetic material in all prokaryotic and eukaryotic cells.
it doesn't occur in different types.
RNA
found in cytoplasm in nucleolus and nucleoplasma and associated with chromosome.
single stranded polynucleotide chain strand in RNA is called on itself and may be united with hydrogen bond.
the sugar is ribose.
don't occur in equal proportion/ratio.
it is heredity material only in few virus.
help in protein synthesis; function as a messenger and translate messages in DNA into protein.
relatively short molecule with low molecular weight.
genetic material only in some viruses.
it occuy in three different types 1) mRNA 2) tRNA 3)rRNA
