Question

In Bryophytes, what is absent?

• A. Embryo formation
• B. Fertilization
• C. Motile gametes
• D. True roots and vascular tissue

Answer 1

The correct option is D True roots and vascular tissue

Bryophyta includes the simplest and primitive land plants, which are characterised by the persence of independent gametophyte and parasitic sporophyte. They are non-vascular land plants with undifferentiated plant body. the plant body is not divided into true leaves, stem and roots. In all bryophytes the ecologically persistent, photosynthetic phase of the life cycle is the haploid, gametophyte generation rather than the diploid sporophyte; bryophyte sporophytes are very short-lived, are attached to and nutritionally dependent on their gametophytes and consist of only an unbranched stalk, or seta, and a single, terminal sporangium.
