In which of the following environments are green algae not found? A.salt water B.freshwater C.moist areas on land D.dry areas on land Because bryophytes do not have vascular tissue, they A.obtain all their water from the surrounding air. B.have true roots, stems, and leaves. C.show alternation of generations. D.grow close to the ground. What is one reason that vascular plants are larger than nonvascular plants? A.Vascular plants live in areas where they can get more water than nonvascular plants can. B,Nonvascular plants cannot live in as many areas as vascular plants, so they stay small. C.Nonvascular plants do not reproduce as quickly as vascular plants do, so they do not grow as large. D.Vascular tissue carries water and nutrients much more efficiently than can be carried by diffusion.
Q1: The answer is D.dry areas on land. Green algae commonly live in the water, either in freshwater or marine ecosystems. Only a few of them are terrestrial but prefer moist over dry areas. Q2: The answer is D.grow close to the ground. Q3: The answer is D.Vascular tissue carries water and nutrients much more efficiently than can be carried by diffusion. Vascular plants have specialised tissues that can transport fluids - vascular tissue. But, bryophytes are nonvascular. They must grow close to the ground so their simple "transportation" tissue can function effectively together.
