Quick Revision: Getting to Know Plants

  • Herbs: Plants with green, tender stems. Usually short (e.g., tomato, wheat).
  • Shrubs: Plants with hard stems branching near the base (e.g., lemon, hibiscus).
  • Trees: Tall plants with hard, thick stems branching above ground (e.g., mango, banyan).
  • Creepers: Weak stems that spread on ground (e.g., pumpkin, watermelon).
  • Climbers: Weak stems that take support to climb (e.g., grapevine, pea).
  • Stem Functions: Conducts water and minerals upward; conducts food downward; bears leaves, flowers, fruits.
  • Leaf Parts: Petiole (attaches to stem) and lamina (broad green part). Veins and midrib for transport.
  • Venation Types: Reticulate (net-like) and Parallel (veins parallel to each other).
  • Transpiration: Loss of water vapour from leaves.
  • Photosynthesis: Process by which green leaves make food using CO2, water, sunlight, and chlorophyll, releasing oxygen.
  • Root Types: Taproot (one main root with lateral roots) and Fibrous roots (many similar-sized roots).
  • Flower Parts: Sepals (outermost), Petals (attract pollinators), Stamens (male part - filament + anther), Pistil (female part - stigma, style, ovary containing ovules).

Chapter Summary: Getting to Know Plants

Plants are classified into herbs (green tender stems), shrubs (hard stems branching at base), and trees (tall with thick stems). Weak-stemmed plants are creepers (spread on ground) or climbers (take support). The stem transports water and minerals upward and food downward. Leaves perform photosynthesis (making food using sunlight, CO2, water) and transpiration (water vapour release). Leaf venation is either reticulate (net-like) or parallel. Plants with reticulate venation have taproots; those with parallel venation have fibrous roots. Flowers consist of sepals, petals, stamens (male), and pistil (female). The pistil contains ovary with ovules that develop into seeds after fertilization.
