Question

What is difference between gametangeal contact and planogametic copulation

Answer 1

Dear Student

Planogametic copulation is a type of sexual reproduction which involves fusion of two naked gametes where one or both of them are motile. The motile gametes are known as planogametes.

In gametangial contact, a group of aplanogametic lower fungi (Oomycetes) produce nonmotile gametes (aplanogametes) that are never released. The male gametangium is called the antheridium and the female oogonium. The gametangia do not actually fuse and do not lose their identity. The antheridium puts out a fertilization tube at the point of contact with the oogonium.
