Simple fruit

Simple fruits can be either dry or fleshy, and result from the ripening of a simple or compound ovary with only one pistil. Dry fruits may be either dehiscent (opening to discharge seeds), or indehiscent (not opening to discharge seeds).Types of dry, simple fruits, with examples of each, are:

* achene - (buttercup, strawberry seeds)
* capsule - (Brazil nut)
* caryopsis - (wheat)
* fibrous drupe - (coconut, walnut)
* follicle - (milkweed)
* legume - (pea, bean, peanut)
* loment
* nut - (hazelnut, beech, oak acorn)
* samara - (elm, ash, maple key)
* schizocarp - (carrot)
* silique - (radish)
* silicle - (shepherd's purse)
* utricle - (beet)

Fruits in which part or all of the pericarp (fruit wall) is fleshy at maturity are simple fleshy fruits. Types of fleshy, simple fruits (with examples) are:

* berry - (redcurrant, gooseberry, tomato, avocado)
* stone fruit or drupe (plum, cherry, peach, apricot, olive)
* pome - accessory fruits (apple, pear, rosehip)
