Key Topics to Revise

1

Fruit, Seed, and Grain

  • Fruit is the enlarged ripened ovary. The ovarian wall forms the fruit wall and encloses the seed.
  • Fruit protects the seed and helps in seed dispersal. Mango and pea pod are examples.
  • Seed is the ripened ovule. It contains the embryo, which develops into a new plant.
2

Types and Classification of Seeds

  • Seeds are broadly of two kinds: monocotyledonous and dicotyledonous.
  • Monocotyledonous seeds have one cotyledon; maize and grasses are examples.
  • Dicotyledonous seeds have two cotyledons; pea, gram, and bean are examples.
