  • High-LET and Low-LET Radiation

    As was written, each type of radiation interacts with matter in a different way. For example charged particles with high energies can directly ionize atoms. Alpha particles are fairly massive and carry a double positive charge, so they tend to travel only a short distance and do not penetrate very far into tissue if at all. However alpha…

  • Cellular Damage – Radiobiology

    All biological damage effects begin with the consequence of radiation interactions with the atoms forming the cells. All living things are composed of one or more cells. Every part of your body consists of cells or was built by them. Although we tend to think of biological effects in terms of the effect of radiation on living cells, in…

  • What is Radiobiology?

    Radiation biology (also known as radiobiology) is a medical science that involves the study of biological effects of ionizing radiation on living tissues. Radiation is all around us. In, around, and above the world we live in. It is a natural energy force that surrounds us. It is a part of our natural world that has been here since…

  • Plant Growth And Development

    The process of plant development starts right from germination under favourable environmental conditions. Generally, plant growth is indeterminate as they retain their capacity to grow throughout their lives because of the presence of meristems. The growth of plants is, however measurable through parameters such as – dry weight, increase in fresh weight, length, area, volume,…

  • Respiration In Plants

    Food that is required for life processes comes from photosynthesis. Cellular respiration results in the release of energy used for the synthesis of ATP which involves glycolysis. Aerobic respiration leads to complete oxidation of organic substances in the presence of oxygen, which is common in higher organisms. To release and utilize the energy stored in…

  • Photosynthesis In Higher Plants

    Plants synthesize their own food through photosynthesis and hence are called autotrophs. Photosynthesis is important since it is the primary source of food for all living entities on earth and it releases oxygen in the atmosphere which we inhale to breathe. It takes place in chloroplasts through light and dark reactions using 4 pigments- Chlorophyll…

  • Mineral Nutrition

    Plant nutrition is an important aspect instrumental in the growth of plants. It gives an insight into the methods used to identify essential elements for the development of plants, the role of these elements, criteria to identify their essentiality, deficiency symptoms and mechanism of absorption of these elements. It also conveys the importance of nitrogen…

  • Transportation In Plants

    Plants have a distinct vascular system (xylem and phloem) which helps in transporting nutrients and water from roots to all the parts of the plant through translocation. Transport of water and nutrients in rooted plants is unidirectional or multi-directional. Modes of transportation can either be passive which occurs through diffusion, facilitated diffusion to be precise…

  • Xylem and Phloem

    These form the vascular tissues of the plant. These are also known as sap. They transport water, sugars and other important substances between the roots, stem and leaves.

  • Roots

    The roots are an underground part of the plant that absorbs water and nutrients from the soil. That is why they are an important part of the plant.
