Detailed explanation-1: -Bryophytes (mosses, liverworts and hornworts) are cryptogams . Bryophytes are in complete contact with water and hence do not require vascular tissue.

Detailed explanation-2: -Nonvascular plants (often referred to collectively as the bryophytes) include three groups: the mosses (Bryophyta), approximately 15, 000 species; liverworts (Hepaticophyta), approximately 7500 species; and hornworts (Anthocerophyta), approximately 250 species (Table 1).

Detailed explanation-3: -Therefore, “zygote undergoes meiosis” is the false statement about bryophytes.

Detailed explanation-4: -They lack true roots, stems, or leaves. They are called non-vascular plants because of the absence of vascular tissues (xylem and phloem) that functions for the conduction of food, water, and minerals.

Detailed explanation-5: -Bryophyta is a group of plants which do not bear fruits, seeds and vascular tissues. They are known as ‘amphibians of plant kingdom’. Their body is thalloid and green due to the presence of chloroplast. Male sexual organ is antheridium and female sexual organ is archegonium.
