Which fruits develop seeds on the outside?

 Strawberries are a notable example of fruits that develop seeds on the outside. Although commonly referred to as berries, strawberries are technically considered aggregate fruits. Each seed-like structure on the surface of a strawberry is actually an individual ovary containing a seed. The fleshy part of the strawberry that we typically eat is derived from the receptacle, the thickened part of the stem where the ovaries are embedded.

This unique characteristic of having seeds on the outside distinguishes strawberries from many other fruits where seeds are embedded within the fruit's flesh. The tiny "seeds" on a strawberry are technically called achenes, and they are the true fruits of the plant. Despite their external placement, these seeds contribute to the plant's reproductive cycle as they can be dispersed to grow new strawberry plants.

In addition to strawberries, there are other fruits where seeds are on the outside or are exposed on the surface. Here are a few more examples:

1. Raspberries:

Like strawberries, raspberries are aggregate fruits where each small, bead-like structure on the surface contains a seed. These structures are also called drupelets.

2. Blackberries:

 Similar to raspberries and strawberries, blackberries are aggregate fruits with small, seed-like structures on the surface. Each of these structures contains a seed.

3. Kiwi:

While not as prominent as in berries, kiwi seeds are distributed throughout the flesh of the fruit, giving them a distinctive appearance. The seeds are edible and add a crunchy texture.

4. Pomegranate:

Pomegranate seeds, also known as arils, are encapsulated by juicy, red pulp. The seeds are individually enclosed in a translucent, edible covering, and they are found on the inside of the fruit.

5. Passion Fruit:

Inside the tough outer rind of a passion fruit, the seeds are surrounded by a jelly-like pulp. The seeds are edible, and the unique flavor of passion fruit comes from this combination of seeds and pulp.

While these fruits have seeds on the outside or with visible seed-like structures, it's important to note that the botanical classification of fruits is not solely based on seed location. Each of these examples showcases the diverse ways in which plants have evolved to disperse seeds for reproduction.
