Question

question 2 of 10
which is an adaptation that helped plants survive on land?
a. placental reproduction
b. development of choanoflagellate
c. haploid forms
d. vascular systems

Explanation:

Vascular systems (xylem and phloem) transport water, nutrients, and sugars. This is crucial for plant survival on land as it allows plants to grow tall and access resources (like water from soil and sunlight). Placental reproduction is in mammals. Choanoflagellates are protists. Haploid forms alone don't explain land survival as well as vascular systems.

Answer:

D. Vascular systems
