Question

question 7 of 25
why did the development of vascular systems help plants move to land?
a. it allowed them to become sporophytes.
b. it allowed gametes to live longer without a water supply.
c. it made it possible to convert sunlight to glucose.
d. it made it possible to move water within the plant structure.

Explanation:

Vascular systems in plants consist of xylem and phloem. Xylem transports water and minerals from the roots to other parts of the plant. On land, a way to move water internally is crucial for survival. Option A is about plant life - cycle stage and not related to vascular - system's role in land - adaptation. Option B is about gametes and not the function of vascular systems. Option C refers to photosynthesis which is not directly related to the role of vascular systems in land - adaptation.

Answer:

D. It made it possible to move water within the plant structure.
