  • Stages required for farming are (1) Choice of seeds for planting (2) Nurturing of crop plants (3) Protection of growing and harvested crops
  • Ribosome - The site of protein synthesis
  • The nucleus is the control centre of the cell, containing genetic material (DNA) that controls all activities within the cell.
  • Cell walls are rigid structures that give plant cells their shape and support them against the turgor pressure inside the cell.
  • Plant cells have chloroplasts which contain chlorophyll, allowing photosynthesis to occur.
  • Chloroplasts contain chlorophyll and are involved in photosynthesis.
  • Vacuoles store water, nutrients, and waste products.
  • Chloroplasts contain chlorophyll, which absorbs light energy from sunlight to carry out photosynthesis.
  • Vacuoles store water, nutrients, and waste products, helping maintain osmotic balance and providing structural support.
  • Mitochondria produce ATP through aerobic respiration, supplying energy for various cellular processes.
  • Animal cells do not have cell walls or chloroplasts as they rely on other organisms for food.
  • Bacteria are single-celled microorganisms found everywhere from soil to water to human bodies.
  • Prokaryotic cells lack membrane-bound organelles and have DNA floating freely in the cytoplasm.
  • Photoperiod is related to the duration of sunlight.
  • Carbohydrates are energy giving, Fats are higher energy giving, Proteins are body building, Vitamins and Minerals are protecting components.
  • Hybridization is the process of cross breeding between two desired plants.
  • The three main types of plant tissue are meristematic, permanent, and vascular tissues.
  • Improvement in crop yields (1) Crop Variety Improvement (2) Crop Production Improvement (3) Crop Protection Management
  • M.S. Swaminathan contributed to increase food grain production by introducing Green Revolution.
  • Kharif Crop - rainy season, June to October -paddy, maize, cotton, green gram, black gram.
  • Rabi Crop - winter season, November to April - wheat, gram, peas, mustard, linseed.
