Strictly speaking, none, since almost all biological specimens are asymmetrical at a detailed level. Every human being has an asymmetrical face, for example.
But an idealised lemon would have onle line of symmetry - along its long axis.
4 Lines of symmetry
2 lines OF SYMMETRY
There is no such thing as 8 lines of symmetry. A circle, for example, has infinitely many lines of symmetry.
a cylinder has 29 lines of symmetry!
5 lines is symmetry
No, a lemon does not have infinite lines of symmetry. It is generally asymmetrical, having a more oval or elliptical shape with one end typically being slightly pointed. While it may have some lines of symmetry depending on its orientation, these are limited compared to shapes like circles or regular polygons, which have infinite lines of symmetry.
