What is BT Cotton? What is BT? Bt, short for Bacillus thuringiensis, is a widely recognized soil bacterium known for its insecticidal properties. This gram-positive and spore-forming bacterium produces unique parasporal crystals during its stationary growth phase, which play a crucial role in pest management. Features of Bt Cotton The following points highlight the key … Read more
What are Bt Crops? Definition of Bt Crops Bt crops, or Bacillus thuringiensis crops, are genetically modified plants that incorporate genes from the bacterium Bacillus thuringiensis. These crops produce specific proteins (Cry proteins) that are toxic to certain insect pests, providing built-in protection against infestations. Common examples include cotton, corn, and brinjal. Bt crops reduce … Read more

What is ATP Synthase? ATP synthase is an essential enzyme complex responsible for the production of adenosine triphosphate (ATP), the primary energy currency in living cells. Often referred to as Complex V in the oxidative phosphorylation pathway, ATP synthase plays a critical role in cellular respiration and photosynthesis, utilizing the proton gradient generated by the … Read more
What are carbohydrates? Types of carbohydrates Carbohydrates can be broadly categorized into three primary types: monosaccharides, disaccharides and oligosaccharides, and polysaccharides. What Is Sucrose? Sucrose is the most prevalent disaccharide found in nature and serves as a principal product of photosynthesis in plants. This sugar is classified as a non-reducing sugar, which limits its chemical … Read more
What is Plant Metabolism? What is Catabolism? Catabolism is a fundamental metabolic process that plays a crucial role in living organisms, including plants and animals. The primary aim of catabolism is to extract energy from biomolecules, converting it into adenosine triphosphate (ATP), which serves as an energy currency for cellular activities. Additionally, catabolism generates essential … Read more
Nutrient transport in plants is a crucial process that ensures the distribution of essential minerals and organic compounds necessary for growth, development, and metabolic functions. This transport occurs through various tissues, primarily the xylem and phloem, each serving distinct roles in the movement of nutrients. The following points outline the key mechanisms and pathways involved … Read more
Water is indispensable for all forms of life, and its role in the plant kingdom is particularly crucial. The relationship between water and plants is prominently illustrated in lush environments where vegetation flourishes, contrasting sharply with arid regions that suffer from water scarcity. Among the various environmental factors influencing plant growth—light, temperature, soil, and water—it … Read more
