How does a ficus tree reproduce (I mean in nature not with human in)?

I know that my ficus is not an angyosperm. It does not produce flowers nor seeds????

Well, the wasp *does* do the pollinating, as in the previous answer. But you are wrong when you say that the fig tree is not an angiosperm because it is. One of my botany textbooks described the structure that we call a fig as "an invaginated floral axis" ... in other words it is derived from something like the finger of a rubber glove with flowers all over it but turned inside out so that the flowers are on the inside. There is a small pore at the top of the fig where the (very small) wasp can get in.



If you cut a young fig lengthways through the pore you should be able to see the small flowers inside. You may even see a wasp if you are looking at a native fig rather than one cultivated for eating ... the wasps are species specific and they are not necessarily found near cultivated figs.

Reply:Ficus (figs) depend on wasps.



From Wikipedia:

"The flowers are pollinated by very small wasps that crawl through the opening in search of a suitable place to reproduce (lay eggs). Without this pollinator service fig trees cannot reproduce by seed. In turn, the flowers provide a safe haven and nourishment for the next generation of wasps."
