Algae is a heterogenous group of organisms containing members having chlorphyll ‘a’ as their primary photosynthetic pigments. These green chlorophyll molecules along with some accessory pigments are contained generally in a membrane bound packet like structure called chloroplast within the algal body. In some members, chloroplast is absent though; such …

Though almost in all cases, when we talk about origin, it goes about the discussion of fossil, bryophytes don’t have any primitive form than what at present-day it is. Usually the study about the origin of bryophyte is something like hypothesis- based upon the comparative studies about the morphology, habitat …

Biomass Biomass is the weight of living matter per unit area at a given time at a given place. Future of Biomass In aquatic ecosystem, produced biomass may either enter into food chain or undergoes destruction. In lentic waters, nutrients present in biomass get recycled, except sedimentation of small fraction. …

Transcription is the synthesis of RNA molecule using one of the DNA strands as a template. It is the first step in the transfer of genetic information from genotype to phenotype. However, this process of transcription is a highly selective one i.e definite genes are transcribed only when their products …

Essential Oil Essential oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. They are usually lipophilic (literally: oil-loving) compounds that usually are not miscible with water. Also, they can be diluted in solvents like pure ethanol and polyethylene glycol. They are also known as volatile oils, ethereal …
