Plant tissue culture involves growing plant cells, tissues, or organs in an artificial nutrient medium under sterile conditions. The success of this technique depends heavily on the composition of the culture medium, which must supply all the necessary nutrients to support growth and development. Nutritional Requirements 1. Macronutrients: Nitrogen (N): Provided as nitrate (NO3^-) or … Read more
Introduction to Plant Tissue Culture: Plant tissue culture refers to the technique of growing plant cells, tissues, or organs in an artificial nutrient medium under aseptic conditions. This method allows for the manipulation of plant material at the cellular level, enabling rapid propagation, genetic modifications, and the study of plant development processes. Historical Development of … Read more
Under certain conditions, cells may accumulate abnormal amounts of various substances. These accumulations can be harmless or associated with varying degrees of injury. The substances can be located in the cytoplasm, within organelles (typically lysosomes), or in the nucleus. They may be synthesized by the affected cells or originate from elsewhere in the body.

Cellular swelling, also known as hydropic change or cytotoxic edema, is a condition where cells increase in volume due to an influx of water. This phenomenon typically occurs as a response to various forms of cellular injury, leading to an imbalance in the regulation of ions and water within the cell. Here’s an in-depth look … Read more
Inhibitors of the Electron Transport Chain (ETC) and Oxidative Phosphorylation The Electron Transport Chain (ETC) and oxidative phosphorylation are critical for ATP production in aerobic organisms. Several inhibitors can interfere with the ETC and oxidative phosphorylation, leading to reduced or halted ATP synthesis. These inhibitors can affect specific complexes within the ETC, mobile electron carriers, … Read more
Oxidative phosphorylation is the process by which ATP is synthesized using the energy released by the transfer of electrons through the Electron Transport Chain (ETC) to molecular oxygen. This process occurs in the inner mitochondrial membrane and is the primary method of ATP production in aerobic organisms. Mechanism of Oxidative Phosphorylation 1. Electron Transport Chain … Read more
