Black holes are generally categorized into three buckets - the largest being called supermassive, the 'medium' being associated with stellar evolution and called 'stellar mass' black holes, and the smallest or tiny ones called "microscopic" black holes.
They are called sphericals.
The hole in the seed coating or testa is called the micropyle. Its function is to allow water to enter to start the seed growing.
The tiny hole on the seed coat is called the micropyle. It allows water and gases to enter the seed, aiding in the process of germination.
They are called sphericals.

The tiny hole is called a stoma. The leaf "breathes" through the hole.If you mean the microscopic holes typically found on the underside of a leaf that allow gases to exchange, then they are called stomata.

The tiny hole in the middle of your eye is called the pupil. It is the opening that allows light to enter the eye and reach the retina, which then sends signals to the brain to create visual images. The size of the pupil can change in response to different lighting conditions to regulate the amount of light that enters the eye.
of course, he is a dig head and with a tiny hole, his girl friend is a beach too!
