What is the role of gametangium in plants?
A gametopyte has haploid set of chromosomes whereas a sporophyte has diploid set of chromosomes. A gametophyte produces the gamets ( male & female) and a sporophyte produces spores in the sporangium. Germination of these spores results in the formation of gametophyte plants.
Is gametangium present in all land plants?
O yes !
What are the spore bearing structures and club mosses and horse tails in the cones of Gymnosperms called?
The spore bearing structures in club mosses and horsetails and the cones of gymnosperms called strobili.

What occurs inside the gametangium?
Meiosis
What are the characteristics of a gymnosperms?
Characteristics of Gymnosperms sporophyte dominant: gametophyte very reduced multicellular female gametangium (archegonium) but no male gametangium (male gametophyte reduced to a few cells and a pollen tube) ovules (modified megasporangium) contain the female gametophyte; after fertilization and formation of zygote, then embryo becomes a seed. no external water required for fertilization vascular cambium leads to secondary growth (wood)
