Question:

Gametophyte of Bryophyte is

Options:

1. Green and vascular.
2. Independent, multicellular.
3. Dependent on sporophyte.
4. Foliose in nature.

Solution:

The gametophyte of bryophytes, which includes mosses, liverworts, and hornworts, is an independent, multicellular stage in the life cycle of these plants. Bryophytes have a unique life cycle with two distinct generations - the gametophyte and sporophyte. The gametophyte is the dominant and independent stage, while the sporophyte is dependent on the gametophyte for nutrition and typically remains attached to it. The gametophyte of bryophytes is typically small, thalloid (flat and ribbon-like) or leafy in nature, and lacks true vascular tissue. It is capable of photosynthesis and produces gametes (sex cells) that fuse during fertilization to form the sporophyte. The gametophyte generation is the stage where sexual reproduction occurs, and it is capable of producing spores that develop into new gametophytes, continuing the life cycle of bryophytes.
