Plant Deficiency Diseases
Plant nutrient deficiencies can cause a range of diseases that significantly impact plant health and productivity. In this video, we explore common plant disorders linked to essential nutrient deficiencies, such as chlorosis, necrosis, blossom-end rot, and more. Learn how to identify the symptoms, including yellowing leaves, stunted growth, and tissue death, and understand the critical role nutrients like nitrogen, phosphorus, potassium, and calcium play in plant development.
Dive deeper into disorders like interveinal chlorosis caused by iron deficiency, purple leaves from phosphorus deficiency, and little leaf disease due to zinc deficiency. Discover how deficiencies in boron, manganese, magnesium, and copper manifest, and gain insights into preventing these issues to ensure healthy, thriving plants. Whether you're a gardener, farmer, or plant enthusiast, this video is packed with essential knowledge to help you diagnose and address plant nutrient deficiencies effectively.

    And where do we classify Phagocytosis?

    • @learnstalkvideos
      @learnstalkvideos 25 วันที่ผ่านมา

      Phagocytosis is not a type of nutrition but the method of taking in substances by single cells. Phagocytosis is taking in solid substances, while pinocytosis is taking in liquid substances. Bacteria for example are exhibit parasitic nutrition. During feeding they take in solid nutrition (phagocytosis) or liquid (pinocytosis). I hope it have been answered

    How to find upthrust when you have given the density of water and the any other density eg paraffin??

    • @learnstalkvideos
      @learnstalkvideos หลายเดือนก่อน

      Upthrust is about the upward force exerted by the substance when emerged in fluid. The substance should likely be solid or enclosed like balloon to experience upthrust. To find the upthrust eg 2kg submerged in water, find its volume from its mass and density of water (V = m / d). Then, upthrust = volume of substance x density of water x gravity. Now, paraffin cant likely experience upthrust in water. But, we can determine wether it sink or float on water. With that, we use relative density (RD). RD of paraffin = density of paraffin / density of water. If the RD > 1, then paraffin sinks. If RD < 1, then paraffin floats on water. I hope this helps. Or I may need more clarification
