ANATOMY OF FLOWERING PLANTS

Image
  What is Plant Anatomy? Plant anatomy is the study of internal structure and organization of tissues in plants. It helps in understanding: Functional adaptation Transport system Growth patterns Tissue Organization in Flowering Plants Flowering plants have three major tissue systems :  Epidermal Tissue System Components: Epidermis Single layer of compact cells No intercellular spaces Covered by cuticle (except roots) Cuticle Made of cutin Prevents water loss Stomata Present mainly on leaves Composed of guard cells Regulate: Gas exchange Transpiration Root hairs Extensions of epidermal cells Increase surface area for absorption Trichomes (in stem) Hair-like structures Protection + reduce transpiration  Functions: Protection Water conservation Gas exchange 🌿 B. Ground Tissue System  Types of Ground Tissue: 1. Parenchyma Living cells, thin cell wall Large vacuole Functions: Storage Photosynthesis ( chlorenchyma ) Air storage ( aerenchyma ) 2. Collenchyma Living cell...

IMPROVEMENT IN FOOD RESOURCES

Image
 All living organisms require food, which provides essential nutrients for body development, growth, and health. Food supplies proteins, carbohydrates, fats, vitamins, and minerals that are necessary for our well-being. Agriculture and animal husbandry are the primary sources of food for humans, obtained from plants and animals respectively. Efforts are made to improve productivity in agriculture and animal husbandry due to several reasons. India, being a populous country with a growing population of over one billion people, requires a significant increase in food production. The current levels of production are insufficient to meet the growing demand for food. Expanding agricultural land is not feasible in India as the available land is already extensively cultivated. Therefore, increasing production efficiency in both crop and livestock farming becomes necessary. Previous efforts like the green revolution and white revolution have contributed to increased food-grain production an...
