The term orange can mean any citrus tree that produces fruit for people to eat. Oranges are a very good source of Vitamin C. Orange juice is an important part of many people's breakfast. The "sweet orange", which is the kind that are most often eaten today, grew first in South and East Asia but now grows in lots of parts of the world.
Oranges are round, orange-coloured fruit that grow on a tree which can reach 10 metres (33 ft) high. Orange trees have dark green shiny leaves and small white flowers with five petals. The flowers smell very sweet which attracts many bees.
