Question

vascular plants typically grow larger than nonvascular plants because
they are able to absorb water and nutrients directly into all of their tissues from the environment.
they are able to deliver water and nutrients more efficiently to all of their tissues.
they produce spores that can liver in very harsh conditions.
they are able to photosynthesize.

Explanation:

To determine why vascular plants grow larger, we analyze each option:

• First option: Nonvascular plants absorb water directly into tissues (vascular plants use a transport system), so this is incorrect.
• Second option: Vascular plants have xylem and phloem, allowing efficient delivery of water and nutrients to all tissues, supporting larger growth. This matches vascular plant anatomy.
• Third option: Spore survival in harsh conditions relates to reproduction, not size, so incorrect.
• Fourth option: Both vascular and nonvascular plants (like mosses) can photosynthesize, so this doesn't explain size difference.

Answer:

B. they are able to deliver water and nutrients more efficiently to all of their tissues.
