Characteristics of Fruits

  • A one-seeded fruit has a thickened hard pericarp, and the seed is attached to the fruit wall
  • The pericarp is marked by the remains of the style and stigma, indicating whether the fruit is superior or inferior

Microscopic Characteristics

  • Colourless fragments of thick-walled polygonal endosperm cells contain globules of fixed oil and aleurone grains
  • Aleurone grains contain micro rosette crystals of calcium oxalate

Capsicum

Origin

  • Dried ripe fruits of Capsicum minimum
  • Family Solanaceae

Geographical Spread

  • Cultivated in India, South America, and Africa

Macroscopic Characters
