What includes stalk and capsule where spores are produced?
The seta is a long erect supporting stalk. At the end of the sporophyte is a pod-like capsule where spores are produced. The seta only occurs in species where the mature capsule is stalked. Transfer cells develop at the sporophyte-gametophyte boundary in the majority of bryophytes, but not all.
What is the stalk that holds the spores called?
In bryophyte: Reproduction and life cycle. Mature bryophytes have a single sporangium (spore-producing structure) on each sporophyte. The sporangium generally terminates an elongate stalk, or seta, when the sporangium is ready to shed its spores.
What do you call a long stem like structure with a capsule at the tip of the moss?
Spore-Bearing Parts The sporophyte stalk, called the seta, bears the sporangium (spore capsule) on its tip. One sporangium may produce up to one million spores. Matured spores are released when the capsule top ruptures and drift off to form new plants.
What is foot seta and capsule?
Moss sporophyte is differentiated into the foot, seta and capsule. Foot serves to get nutrition for developing sporophyte. Seta is the stalk of the capsule. Capsule bears archespores within the capsule wall.
What are spore capsules?
A spore capsule is part of the sporophyte, which develops from a fertilized egg. In some species the fertilized egg will produce just spore capsules whereas in others fertlized eggs will also produce a supporting stalk for the spore capsule. A germinating spore produces a new gametophyte.
Where are the spores produced?
Spores are most conspicuous in the non-seed-bearing plants, including liverworts, hornworts, mosses, and ferns. In these lower plants, as in fungi, the spores function much like seeds. In general, the parent plant sheds the spores locally; the spore-generating organs are frequently located on the undersides of leaves.
Where are spores found in ferns and mosses?
sporangia
Ferns produce spores on the undersides of their fronds in cases called sporangia, and mosses produce their spores in capsules that are borne on the ends of stalks.
Where are spores found in mosses?
capsule
Mosses reproduce by spores, which are analogous to the flowering plant’s seed; however, moss spores are single celled and more primitive than the seed. Spores are housed in the brown capsule that sits on the seta.
