In many mosses, the leaves of the lower layer become yellow-brown due to the destruction of pigment in low light conditions.
Moss has no roots. They are attached to the ground by rhizoids - multicellular hair-like processes.
Mosses reproduce by spores that mature in the sporangium of the sporophyte. The moss sporophyte is represented by a leg with a capsule. But he does not live long and dries up quickly. The dried box opens and spores wake up from it. From them grows a plant with a haploid set of chromosomes - perennial, green; female or male. In the life cycle of moss, gametophyte prevails over sporophyte.
- In the Mesozoic, ferns dominated the Earth, in contrast to mosses.
- Ferns were the raw material from which coal, oil, gas were formed, and mosses are the basis for the formation of peat.
- Mosses are dioecious plants, ferns are monoecious.
- Moss leaves produce only chlorophyll, fern leaves are a place for photosynthesis and spore deposition.
- In mosses - rhizoids, in ferns - rhizomes.
- Moss has leaves, ferns have fronds.
- Ferns have a formed conductive and parenchymal tissue; such differentiation is not observed in mosses.
- In the life cycle of moss, the gametophyte prevails over the sporophyte, and in the fern, the sporophyte prevails over the gametophyte.
