Which fruits develop seeds on the outside?

 

There's a bit of a misconception about fruits having seeds on the outside. In reality, fruits develop from the flower's ovary, and seeds typically form inside the ovary. However, there is one fruit that appears to have seeds on the outside: strawberries.

The tiny yellow or red dots on the surface of a strawberry aren't actually seeds. They are achenes, which are single-seeded dry fruits that develop from an individual carpel. The fleshy part of the strawberry that we eat is actually the receptacle, the swollen base of the flower that holds the ovaries. So, while the achenes technically contain seeds, they aren't true seeds on the outside of the fruit in the botanical sense.

Fruits that develop seeds on the outside are typically referred to as "aggregate fruits." The most common examples include:

1. Strawberries: Each seed-like structure on the outside of a strawberry is actually a separate ovary containing a seed.
2. Raspberries: Similar to strawberries, each small bump on a raspberry represents an individual drupelet, which contains a seed.
3. Blackberries: Blackberries also consist of multiple drupelets, each containing a seed.

These fruits are unique in that they are formed from multiple ovaries of a single flower, giving them their characteristic appearance of seeds on the outside.
