berry

Male and female flowers of the black mulberry grow on separate bushes but the fruits form on the female trees whether or not they have been fertilized.

Fleshy, many-seeded fruit that does not split open to release the seeds. The outer layer of tissue, the exocarp, forms an outer skin that is often brightly coloured to attract birds to eat the fruit and thus disperse the seeds. Examples of berries are the tomato and the grape.

A pepo is a type of berry that has developed a hard exterior, such as the cucumber fruit. Another is the hesperidium, which has a thick, leathery outer layer, such as that found in citrus fruits, and fluid-containing vesicles within, which form the segments.
