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).

Getting to Know Plants Class 6 Questions and Answers (FAQ)

What are the main parts of a plant and their functions for Class 6 Science?
A plant has four main parts: (1) Roots - anchor the plant to soil and absorb water and minerals; (2) Stem - conducts water and minerals upward and food downward, bears leaves, flowers and fruits; (3) Leaves - perform photosynthesis (make food) and transpiration (loss of water vapour); (4) Flowers - reproductive parts that produce seeds and fruits. Each part has a specific function that helps the plant survive and grow.
What is the difference between herbs, shrubs, and trees?
Herbs are small plants with soft, green and tender stems (e.g., grass, wheat, tomato). Shrubs are medium-sized plants with hard, woody stems that branch near the base (e.g., rose, hibiscus, lemon). Trees are tall plants with a thick, woody main stem called a trunk that branches above the ground (e.g., mango, banyan, neem). This classification is based on stem characteristics and overall plant height.
What is photosynthesis and transpiration in plants?
Photosynthesis is the process by which green leaves make food using carbon dioxide, water, sunlight, and chlorophyll. During this process, oxygen is released as a by-product. Transpiration is the loss of water vapour from the leaves through tiny pores called stomata. Transpiration creates a suction force that pulls water up from roots through the xylem, helping in the transport of water and minerals throughout the plant.
What are the two types of leaf venation and how do they relate to root systems?
There are two types of leaf venation: (1) Reticulate venation - veins form a net-like pattern (e.g., mango, hibiscus, peepal). (2) Parallel venation - veins are parallel to each other (e.g., grass, wheat, banana). There is a general correlation between leaf venation and root system: plants with reticulate venation usually have taproots (one main root with lateral branches), while plants with parallel venation typically have fibrous roots (many similar-sized roots from the base).
What are the male and female reproductive parts of a flower?
The male reproductive part of a flower is the stamen, which consists of the anther (produces pollen grains) and the filament (stalk that supports the anther). The female reproductive part is the pistil, which consists of three parts: stigma (sticky top that receives pollen), style (tube connecting stigma to ovary), and ovary (contains ovules). After pollination and fertilization, the ovary develops into a fruit and the ovules develop into seeds.

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.
