Bryophytes: Habitat and Reproduction

Bryophyte Habitat

• Bryophytes are often found in moist environments, thriving in places like forests, wetlands, and along streams.
• They prefer shaded areas to minimize water loss and can adapt to a variety of substrates.

Marchantia sp.

• Marchantia sp. serves as a representative of primitive forms of bryophytes, exhibiting both thallus and gametophyte structures.
• It produces gemmae, small reproductive structures located in gemma cups, which facilitate asexual reproduction.
• The thallus can be differentiated into male and female forms, essential for sexual reproduction.

Gametophyte and Sporophyte

• The gametophyte stage is the dominant and photosynthetic phase in Marchantia.
• Sporophyte generation is dependent on the gametophyte for nutrition and support; it develops from the fertilization of gametes.

Moss - Funeria sp.

• Funeria sp. represents a type of moss, characterized by a distinct branch structure that can be observed in magnified views.
• Mosses exhibit similar gametophyte and sporophyte phases, but their structures and reproductive measures differ from those of liverworts like Marchantia.

Drawing Bryophytes

• Drawing techniques for Marchantia gametophyte emphasize accurate labeling and structural details.
• Moss diagrams should include specific features such as filaments, leaf arrangement, and sporophyte capsules for clarity in identification.
