What is a drupe?
A drupe is a type of fruit that develops from a single ovary with a hard endocarp surrounding the seed. The outer fleshy part of the fruit is often edible and contains the seed within. Drupes are commonly referred to as stone fruits due to the hard pit or stone that encases the seed. They can vary in size, shape, and color, but they all share the characteristic of having a single seed enclosed within a hard shell.
How are drupes classified?
Drupes are classified based on the number of seeds they contain. There are three main categories of drupes:
1. Simple drupes: These drupes have a single seed enclosed within a hard shell. Examples of simple drupes include cherries, peaches, and plums.
2. Aggregate drupes: These drupes contain multiple seeds that are surrounded by a fleshy outer layer. Examples of aggregate drupes include raspberries and blackberries.
3. Multiple drupes: These drupes are formed from a cluster of flowers that fuse together to form a single fruit with multiple seeds. Examples of multiple drupes include pineapples and mulberries.
What are some common examples of trees that produce drupes?
There are many trees that produce drupes, some of the most common examples include:
– Peach trees: Peach trees produce delicious and juicy drupes with a soft outer skin and a hard pit inside.
– Cherry trees: Cherry trees produce small, round drupes with a sweet and tart flavor.

How do drupes contribute to the ecosystem?
Drupes play a vital role in the ecosystem by providing food and shelter for a variety of animals. Many birds and mammals rely on drupes as a food source, helping to disperse the seeds and promote plant growth.
