The tangerine is a type of orange. Its scientific name varies. It has been treated as a separate species under the name Citrus tangerina or Citrus x tangerina or treated as a variety of Citrus reticulata. Citrus tangerina is also treated as a synonym of Citrus deliciosa. It is a group of orange-colored citrus fruit consisting of hybrids of mandarin orange (Citrus reticulata) with some pomelo contribution. Tangerines are smaller and less rounded than common oranges. The taste is considered less sour and sweeter, and stronger than that of an orange. A ripe tangerine is firm to slightly soft and pebbly-skinned with no deep grooves, as well as orange in color. The peel is thin, with little bitter white mesocarp. All of these traits are shared by mandarins generally.
 

Fruits II

In botany, a fruit is a seed-bearing structure in flowering plants formed from the ovary after flowering.

Fruits are how flowering plants disseminate their seeds. Edible fruits, in particular, have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food.
