  1. FRUITS Fruits can be divided into three categories: 1. Simple fruit - a fruit formed from a single ovary of a single flower (monocarpous or syncarpous ovary) 2. Aggregate fruit - a fruit formed from several ovariesof a singleflower (apocarpous) e.g. Anona 3. Multiple fruit - a fruit formed from the ovaries of flowers borne in a compact inflorescence. The fruits unite at maturity e.g. jackfruit, pineapple

  2. Simple fruits • Dry indehiscent fruits • Dry dehiscent fruits • Succulent/Fleshy fruits A fruit : - pericarp + the seed (inside) - is a ripened ovary/ovaries generally containing one to many seeds inside Pericarp : exocarp/epicarp + mesocarp + endocarp ** Following pollination and fertilization in a flower, the ovule develops into a seed while the ovarywall forms the fruit pericarp
