Why Are Fruits Spherically Shaped?


In nature, most fruits are spherically shaped because of the shape of plant cells. Without a curved boundary, plasmodesmata between cells can’t connect.

Similarly, the spherical shape of the cell wall edge facilitates this connection. And, as the larger cells collaborate to form a germinating bud, they must also be a sphere.

So, despite our best efforts to make a fruit shaped like a disc, nature has its own reasons for making most fruit shapes.

Unique Facts About Fruits

Ten-rib pattern of Korean melons remains preferred state for spheroids

Despite varying morphological characteristics, the ten-rib pattern of Korean melons is the preferred state of spheroids.

This can be explained by mechanical principles and the differences in the thickness of the fruit’s skin. However, these differences cannot be ruled out. The ten-rib pattern of Korean melons is largely based on its unique genetic make-up.

Korean melons have a mild aroma when ripe. They are heavy for their size and yield when pressed. Korean melons are edible from rind to seed.

Their crisp white flesh is firm and filled with ivory seeds. The melon’s mild flavor is reminiscent of bananas, with some floral overtones. These characteristics make the ten-rib pattern of Korean melons a popular fruit in Korea.

Spheroids have ten ribs

The ten ribs of the human skeleton are wedge-shaped, with the first rib being the broadest and sharpest. The rib’s tubercle articulates with the body of the T1 vertebra.

It has a large articular facet and two grooves for the subclavian vessels. The ribs have a flat portion of bone called the rib’s neck, which connects the head to the body.
