Study Notes

Fruit Types

Fruits can be categorized in four ways: floral origin, tissue origin, succulence, and dehiscence
Aggregate fruit: develops from one flower with several unfused carpels, each carpel becoming a 'fruitlet', which fuse together (partially or mostly), e.g. sweetsop, soursop, raspberry
Simple fruit: develops from one flower with one carpel or fused carpels, e.g. mango, apple, tomato
Multiple fruit: develops from inflorescence, several fruits merge and fuse into a single fruit body, e.g. pineapple, noni, breadfruit

Tissue Origin

True fruit: develops from nothing but ovary wall, most fruits, e.g. temperate apple, temperate pear
Accessory fruit: develops from other parts of flower as well as ovary wall, e.g. cashew apple, strawberry

Succulence and Dehiscence

Fruits may be fleshy/succulent (juicy) or dry (stony, papery, woody, etc.)
Fruits may be dehiscent (open to release seeds) or indehiscent (remain closed, seeds retained and dispersed within fruit)

Fruit Structure

Fruit consists of three layers: outermost epicarp (exocarp), middle layer mesocarp, and inner layer endocarp
Pericarp: the three layers collectively
Fruit has two 'scars': scar of attachment to receptacle and scar from dried/withered style

Inflorescence

Inflorescence: cluster of flowers in a particular arrangement
Examples of inflorescence: umbel, capitulum/head, spike/raceme

Flowers

Flower diversity: modifications/variations of structure
Modifications related to methods of pollination and/or seed dispersal
Examples of flower diversity: number of whorls, number of parts per whorl, fusion of parts, planes of symmetry
