... leafy, green gametophyte. The sporophyte depends on the gametophyte for food and water. When we think of the green carpet of mosses, it is the gametophyte we are seeing. – The ferns sporophytes have leaves which are much larger than the gametophytes. They have clusters of sporangia, where the spores ...
