What is the main difference between bryophytes and ferns?
The key difference between bryophytes and ferns is that the bryophytes are nonvascular plants while ferns are vascular plants. In simple words, bryophytes lack xylem and phloem while xylem and phloem are present in ferns. Furthermore, bryophytes do not have true leaves while ferns have true leaves.
Where do Pteridophytes grow? In fact, they can be considered as the first terrestrial vascular plants, showing the presence of the vascular tissue, xylem, and phloem. Mostly, we find these plants in damp and shady places. Also, most ferns are grown as ornamental plants.
Which is primitive bryophyte?

What is gemma Cup? Gemmae cups are cup-like structures containing gemmae. The gemmae are small discs of haploid tissue and they directly give rise to new gametophytes. A gemma (plural gemmae) is a single cell or a mass of cells, or a modified bud of tissue, that detaches from the parent and develops into a new individual.
What is gemma Class 11?
Gemmae are green, multicellular, asexual buds, which develop in small receptacles called gemma cups located on the thalli. The sporophyte is differentiated into a foot, seta, and capsule. After meiosis, spores are produced within the capsule, the spores germinate to form free-living gametophytes.
