When we heard about bacteria the first thing that came to our mind is that it must be harmful for us. And it’s  very common because the word”bacteria” generally indicates some sort of disease and is likely to repulse and scare we off. Scientists estimate that only 1-10% of total …

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. This Terpenoids are a diverse group of naturally occurring organic compounds mostly found in plants. They are any of a class of hydrocarbons that consist …

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, …

The male sterility which  is governed by both nuclear and cytoplasmic genes is known as Cytoplasmic Genetic Male Sterility or CGMS. While CMS is controlled by an extra-nuclear genome, nuclear gene may have the capability to restore fertility. When nuclear restoration of fertility genes (“Rf”) is available for a CMS …

Male sterility, as the name indicates, is the inability of a plant to produce male reproductive organ, the viable pollens. Male sterility can occur due to extra-nuclear genetic or nuclear genetic condition. Cytoplasmic Male Sterility (CMS) refers to the inability of a plant to produce viable pollens due to cytoplasm …

The origin of life on Earth is a scientific problem which is not yet solved. There are plenty of ideas, but few clear facts. It is generally agreed that all life today evolved by common descent from a single primitive life form. It is not known how this early form …

Water Microbiology  Water is the vital element for every living organisms on earth. So, it’s needed to ensure safe access to clean drinking water for all as most of the important bacterial diseases are transmitted through water . Water microbiology is the study of microorganisms like bacteria, viruses, protozoa, microscopic …

A model organism is a non human species that is used as a framework to develop and standardize the analysis which is applicable to other species. It’s an in vivo model which is extensively used to study human diseases when human experimentation would be unethical.  In studying human diseases,  model …
