The first generation of mosses starts with germination of spores to develop into gametophyte. The male and female gametophytes produce anthridia and archegonia. Motile antherozoids are released from anthridia and make their way to archegonia through water. The egg inside archegonium is fertilized to form the zygote. The zygote develops into a sporophyte, which remain dependent on the gametophyte.
Yes, according to the botany of the World, mosses of the plant group evolved first. You can get that book from any public library.
The haploid gametophyte generation
Gametophyte
The Sporophyte is the dominant generation of the club moss, which is a Lycopodium. Also, club mosses are vascular plants, and the diploid generation is dominant for vascular plants.
Unlike true mosses, club mosses have vascular tissue.
Club mosses are vascular while bryophytes (true mosses) are nonvascular.
mosses meet their needs by mosses finding their needs
No, mosses do not have secondary growth. Secondary growth takes place in vascular plants. Mosses are non-vascular.
gametophyte generation
Second generation produced in mosses is sporophyte on the gametophytic plant body.
In mosses, the photosynthetic cell possesses a spore capsule. A good example is the polytrichum which has a capsule with a sterile jacket.
Gametophyte
The sporophyte generation is dominant in ferns.
The Sporophyte is the dominant generation of the club moss, which is a Lycopodium. Also, club mosses are vascular plants, and the diploid generation is dominant for vascular plants.
Mosses are non-vascular plants whereas ferns are vascular. In ferns Sporophyte is dominant but in mosses gametophyte is dominant generation. Ferns have definite roots but in mosses leaves and roots are mostly false.
a tracheophyte is a vascular plant which is capable of conducting water, minerals and photosynthetic products through the plant. This includes conifers, gymnosperms, angiosperms, club mosses and ferns.
An eyespot (or photoreceptor) and a flagellum.
Unlike true mosses, club mosses have vascular tissue.
Club mosses are vascular while bryophytes (true mosses) are nonvascular.
