F. Fruit

Angiosperms produce fruit after fertilization from the ovary.

Types Parthenocarpic Fruits

  • Fruits produced from ovary

    without fertilization

  • Example: Seedless grapes
True Fruit
  • Develops

    only from ovary

  • Example: Mango
False Fruit (Pseudocarp)
  • Develops from

    other floral parts than ovary

  • Example: Apple

Structure of a True Fruit

Components:

  • Protective wall (Pericarp): Contains seeds

In Fleshy Fruits, pericarp is further divided:

  • Epicarp: Outer layer
  • Mesocarp: Middle layer
  • Endocarp: Inner layer
  • Example: Mango

 

Types of Fruits

Simple Fruits

  • Develop from

    one ovary of one flower

Dry Fruits
  • Thin pericarp
  • Dehiscent: Breaks open at maturity (e.g., Capsule, Legume)
  • Indehiscent: Does not break open (e.g., Achene, Caryopsis, Cypsela)

Fleshy Fruits

  • Thick pericarp
  • Examples: Berry, drupe

Aggregate Fruits

  • Develop from

    many ovariesof

    apocarpous gynoecium

  • Also called collection/Etario
  • Example: Etario of achenes = Strawberry
Composite Fruits
  • Develop from

    one whole inflorescence

  • Examples:
    • Syconus: Fig
    • Sorosis: Pineapple
