Why Electron Microscopy Matters? The microscopic world extends beyond the reach of light microscopes, which are limited to resolving details down to about 0.2 µm, leaving structures like viruses (20–300 nm) and ribosomes (25–30 nm) invisible. Electron microscopy (EM) overcomes this barrier by using electron beams to achieve much higher […]
Why Microscopy Matters in Biology? Microscopy is a crucial tool in biology, allowing scientists to explore the invisible world of microbes and cells. It reveals structures too small for the naked eye, from bacterial morphology to eukaryotic cell organization. Without microscopes, studying soil bacteria or observing mitosis in onion root […]
Introduction Halophytes are unique plants that thrive in saline habitats where most other plants cannot survive. Found in coastal marshes, mangrove forests, estuaries, and salt deserts, these plants have developed specialized features to cope with high salt concentrations and waterlogged conditions. Among the most studied halophytes is Avicennia, a mangrove […]
Microscopy is one of the most powerful tools in biology, allowing us to visualize structures invisible to the naked eye. For undergraduate and postgraduate students, understanding microscopy techniques is essential for both coursework and research. Among these methods, dark field microscopy is particularly fascinating because it reveals fine details in […]
An electron microscope uses a beam of electrons instead of light to magnify specimens. It provides very high resolution, allowing scientists to see structures at the molecular or atomic level. There are two main types: transmission electron microscope (TEM) and scanning electron microscope (SEM). It is widely used in biology, […]
