Question

The physical characteristic that is the main difference between the Bryophytes and members of the Lycophytes and Pteridophytes is the presence of ____________.

Answer 1

Answer: VASCULAR TISSUES

Explanation: BRYOPHYTES are small, non-vascular plants, such as mosses, liverworts and hornworts. they do not have seeds or flowers,rather they reproduce via spores.

LYCOPHYTES are also known as the 'fern allies',they are a clade of vascular plants similar to ferns but have unique leaves called microphylls.They are primitive plants and lack seeds, wood, fruit and flowers.

PTERIDOPHYTES are plants that do not have any flowers or seeds. Hence they are also called as Cryptogams. They include ferns and horsetails. In fact, they can be considered as the first terrestrial vascular plants, showing the presence of the vascular tissue, xylem, and phloem.

The presence of vascular tissues is the main physical characteristic that differs the bryophytes from the members of the lycophytes and pteridophytes, some of the characteristics they have in common are spores, chloroplasts and seeds.

Answer 2

Answer: Vascular tissues

Explanation:

The bryophytes are the plants that lack vascular tissues called as xylem and phleom. The bryophytes vary in diversity these includes the simple plants like mosses, liverworts and hornworts. These plants obtain the water and nutrients through the process of simple diffusion. The bryopytes absorb the water and nutrients at the surface of soil and transport them through cell to cell contact. The lycophytes and pteriodophytes are the vascular plants as they posses the xylem and phloem.
