Question

A research station botanist observes that flowering plants dominate most terrestrial habitats, even though they evolved relatively recently compared to other plant groups. What evolutionary advantages helped angiosperms become so successful?
Question 2 options:

Flowering plants can survive without water, unlike all other plant groups in terrestrial environments

Flowers and fruits enhanced reproduction and seed dispersal compared to earlier plant groups like conifers

Flowering plants were the first to evolve vascular tissue for water and nutrient transport systems

Angiosperms were the first plants to develop photosynthesis for energy production from sunlight

Answer 1

Correct answer:
Flowers and fruits enhanced reproduction and seed dispersal compared to earlier plant groups like conifers.

Brief explanation:
Angiosperms evolved flowers that promote efficient pollination (often via animals) and fruits that protect seeds and promote dispersal. They also have innovations like double fertilization (producing nutrient-rich endosperm) and more efficient xylem vessel elements, which together allow faster life cycles, greater reproductive success, and exploitation of diverse habitats — explaining their dominant diversity. The other choices are incorrect: photosynthesis and vascular tissue predate angiosperms, and no terrestrial plants “survive without water.”
