How many petals does an orange have?

The number of orange petals is uncertain. Generally, it is 7~ 10 petals, 6 petals when it is less, and more than 20 petals when it is more. The orange petals developed from the ovary, which is a carpel structure. When oranges grow up, the cells connected with different carpels will gradually expand, vacuolate and then die, leaving only thin cell walls connected. The cell wall of carpel cells thickens and becomes the membrane of each orange. So oranges become petals.

Peel off the orange peel and break the orange petals, and then take a closer look at where the petals are connected. There are some thin white hairs, which are the cell walls of dead cells.
