Botanically, fruits are the edible tissues surrounding the seeds of flowering plants. The fruit protects the seeds and aids in dispersal. Most fruits are composed of three layers: an inner endocarp, a middle mesocarp, and an external exocarp. All three make up the pericarp, which grows from a ripened ovary surrounding the seed.
Most fruits are simple fruits, which form around one ovary. These include bananas, watermelons, tomatoes, pears, apples, peaches, cherries, and oranges.
Other fruits are compound fruits, which form around a group of ripened ovaries. These include aggregate fruits, which form around a single flower possessing many ovaries. Common aggregate fruits include blackberries and raspberries. Another kind of compound fruit, called “multiple fruits”, are produced from multiple flowers on one stem. Multiple fruits include mulberries, pineapples, and figs.
Horticulturalists define fruits as edible fleshy structures containing seeds that grow on a perennial plant. In horticulture, a fruit can be eaten raw, immediately after picking, with very few exceptions (like the plantain). Fruits can grow on woody shrubs and trees, vines, and herbaceous crops.
In horticulture, fruits are divided into three categories: temperate, subtropical, and tropical fruits. Temperate fruit, like apples and quince, require a cold season every year to produce fruit and are very frost-tolerant. Subtropical fruits need mild temperatures, but can withstand light frost. Subtropical fruits include many familiar citrus fruits, such as grapefruits and oranges. Tropical fruits require consistent warm temperatures without frost, usually above fifty degrees Fahrenheit for the coldest days. Examples would include bananas and pineapples. Most tropical fruits also require humid climates to thrive.
