The Scanning Electron Microscope (SEM), a type of electron microscope, is a powerful analytical tool that revolutionized imaging in biological sciences. Unlike conventional light microscopes that rely on visible light, the SEM uses a concentrated beam of electrons to generate high-resolution, three-dimensional images of specimen surfaces. For biology students and […]
The Transmission Electron Microscope (TEM), a type of electron microscope, is one of the most powerful instruments in contemporary biological and materials research. It has profoundly enhanced our understanding of cellular organization and biomolecular architecture by providing images at resolutions far beyond those achievable with light microscopes. Unlike optical microscopes […]
Gymnosperms are a group of seed-producing plants characterized by naked seeds, typically borne on cones or strobili. They are among the earliest seed plants and have significant ecological and evolutionary importance. Unlike angiosperms, gymnosperms do not produce flowers or fruits. Understanding their origin, evolution, and diversification provides critical insights into […]
When Gregor Mendel first experimented with pea plants, he discovered that traits are passed from parents to offspring in predictable ways. His work gave us the basic rules of dominant and recessive inheritance. But as scientists dug deeper, they found that inheritance is not always as simple as Mendel described. […]
Parasitic plants are a fascinating group that depend wholly or partly on other living plants (hosts) for nutrition. Unlike autotrophic plants, which prepare their own food through photosynthesis, parasitic plants develop specialized adaptations that enable them to attach to hosts and extract water, minerals, and organic nutrients. One of the […]
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 […]
