Key Topics to Revise

1

Parts of a Flower

  • A flower has four whorls: Calyx, Corolla, Androecium, and Gynoecium.
  • Calyx is the outermost whorl made of sepals; protects the flower in bud stage.
  • Corolla is the second whorl made of petals; usually bright and fragrant to attract pollinators.
2

Pollination and Fertilization

  • Pollination is the transfer of pollen from anther to stigma.
  • Two types: Self-pollination (same flower or same plant) and Cross-pollination (different plants).
  • Agents of cross-pollination: Wind, water, insects, animals.
3

Fruit and Seed Formation

  • Fruit is the ripened ovary of a flower.
  • False fruits (like apple) develop from thalamus, not ovary.
  • Pericarp has three layers: Epicarp (outer), Mesocarp (fleshy), Endocarp (inner hard layer).
4

Seed Structure and Germination

  • Two types of seeds: Dicot (e.g., bean) and Monocot (e.g., maize).
  • Dicot seeds have two cotyledons; monocots have one.
  • In bean seeds, cotyledons store food; in maize, endosperm stores food.
