Algae is a heterogeneous group of organisms containing members having chlorophyll ‘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, the chloroplast is absent though; such as …

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 …

Every cell of an organism possesses all the structural genes or cistrons. The genes produce proteins and control the activities of the organism. But a genetic system doesn’t allow them to function all at a time in order to avoid enzymatic chaos. Many gene products are only needed occasionally by …

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 …

An enormous range of plant substances are covered by the term ‘Terpenoids’ which is used to indicate that all such substances have a common origin.

ঢাকা বিশ্ববিদ্যালয়ের উদ্ভিদবিজ্ঞানের ছাত্রছাত্রীদের গাছের নাম জানা শুরু হয় কার্জনের গাছ দেখেই। কত হরেক রকম গাছ আছে আমাদের এই কার্জনে, আর উদ্ভিদবিজ্ঞানের বাগানে ঢুকলে তো কথাই নেই। তবুও বাস্তবতা হচ্ছে চোখের সামনের অধ্যয়নের বিষয় থাকলেও চার বছর ধরে দেখা এই গাছগুলোর নাম জিজ্ঞেস করা হলে হয়তো আমাদের উদ্ভিদবিজ্ঞানেরই অনেক ছাত্র …

INTRODUCTION Ascomycota is a phylum of fungi classification containing a compartmentalized mycelium, a dikaryotic life stage in the life cycle, plectenchymatous structures associated with spore production, conidia, and sometimes complex dispersal systems. The primitive morphological character that distinguishes members of Ascomycota from all other fungi is the Ascus (pl. asci, …
