What are Viruses? Origins of Viruses Viruses have likely existed since the earliest life forms and have evolved alongside cellular organisms. Due to their lack of fossil records, the origins of viruses remain unclear, and scientists use molecular biology techniques to explore their evolutionary history. Three primary hypotheses attempt to explain how viruses may have … Read more
The fungi are classified based on the characteristics of the sexual spores and fruiting bodies present during the sexual stages of their life cycles. Therefore, based on characteristics of their sexual stages and morphology of their asexual spores and thalli they are classified into different groups.
What is Fungi? Definition of Fungi Fungi are eukaryotic organisms that include yeasts, molds, and mushrooms. They are heterotrophic, meaning they obtain nutrients by absorbing dissolved molecules from their surroundings, and they play a vital role in decomposing organic matter. Fungi are classified in the kingdom Fungi and are distinct from plants, animals, and bacteria, … Read more

What is Cell Cycle? Definition of Cell Cycle The cell cycle is a series of sequential events that occur in a cell, leading to its growth, DNA replication, and division into two daughter cells. It consists of interphase, where the cell prepares for division, and the M phase, which includes mitosis and cytokinesis. This process … Read more
Types of Membrane Transport Membrane transport refers to the movement of molecules across cell membranes. This process is essential for maintaining cellular homeostasis and involves multiple mechanisms, which can be classified based on energy requirements. The types of membrane transport are broadly categorized into passive and active transport. Passive transport It is a sort of … Read more
What is Plant Tissue Culture? Plant tissue culture Definition Plant tissue culture is a biotechnology technique that involves growing plant cells, tissues, or organs in a controlled, sterile environment on a nutrient medium. This method exploits the totipotency of plant cells, allowing for the rapid propagation of plants, production of disease-free specimens, and conservation of … Read more
What is Plasmodesmata? Definition of Plasmodesmata Plasmodesmata are microscopic channels that traverse the cell walls of plant and algal cells, allowing for direct transport and communication between adjacent cells. These structures enable the movement of water, proteins, small RNAs, and other metabolites, playing a crucial role in cellular connectivity and plant physiology. Structure of Plasmodesmata … Read more
What is Digestive System? How Does the Digestive System Work? Types of Digestive System The digestive system can be categorized into two primary components: the gastrointestinal (GI) tract and the accessory digestive organs. Understanding these components is essential for comprehending how the body processes food and absorbs nutrients. Each part plays a distinct role in … Read more
