A Brief Look at Drupes
In a recent post we looked at pome fruit. In today’s post, we do something similar and look at drupes.
What is a Drupe?
A drupe is a fruit that has the following main components:
Skin – this is called the exocarp. It is formed by from the wall of the flower ovary.
Pulp – this is called the mesocarp
Shell – this is called the endocarp
Seed – generally there is one seed
The exocarp, mesocarp, and endocarp together are called the pericarp.
A drupe is also referred to as a stone fruit.
What are Some Examples of Drupes?
Drupes include fruits such as plums, cherries, apricots, olives, and peaches. They also include things such as almonds and pecans.
What Makes A Drupe A Simple Fruit?
A simple fruit is a fruit which is formed from one ovary and a single pistil from one flower. They can also form from a compound ovary. Drupes are simple fruits because they form this way.
Examples of simple fruits include things such as apples, peaches, grapes, lemons and melons. Simple fruits can be further divided into subcategories such as drupes and pomes.
In addition to simple fruits, there are also aggregate fruits and multiple fruits. Aggregate fruits are formed from more than one ovary of one flower. Examples include strawberries and raspberries. Multiple fruits are formed from multiple flowers. Examples include fruits like pineapples and blackberries.
In a summary:
One ovary from one flower – simple fruit
More than one ovary from one flower – aggregate fruit
Multiple flowers – multiple fruit
Drupes are simple fruits because they form from one ovary from one flower.
