Which of the following is true about bryophytes?
Solution
(d) Bryophyte is a group of embryo producing plants, which do not bear fruits, seeds and any vascular tissue. They are known as ‘amphibians of plant kingdom’. Body is thalloid and green (due to presence of chloroplast). Male sexual organ is antheridium and female sexual organ is archegonium.
