Answer:
A. Vascular tissues and extensive root systems
B. Waxy cuticles and stomata
C. Lack of seeds and presence of spores
D. Ability to absorb water and nutrients from both air and water
Step-by-step explanation:
A. Vascular tissues and extensive root systems: Bryophytes have developed vascular tissues, such as xylem and phloem, which enable them to absorb water and transport nutrients. They also have an extensive root system that helps them to anchor themselves in the aquatic environment and absorb moisture and nutrients from the surrounding environment.
B. Waxy cuticles and stomata: Bryophytes have developed a waxy cuticle to protect themselves from drying out in the terrestrial environment. They also have stomata, which are tiny pores on the surface of their leaves, that allow them to exchange gases with the environment.
C. Lack of seeds and presence of spores: Bryophytes lack the ability to produce seeds, and instead reproduce through the dispersal of spores. Spores are less vulnerable to drying out, and so can survive in both aquatic and terrestrial environments.
D. Ability to photosynthesize and reproduce through spores: Bryophytes are able to photosynthesize in both aquatic and terrestrial environments, thanks to their waxy cuticle and stomata. They are also able to reproduce using spores, which allows them to disperse and colonize both aquatic and terrestrial habitats.
