II. sperm transfer.
III. desiccation.
IV. animal predation.

Question

Quizplus · Accepted Answer

I. Sources of water were limited on land compared to aquatic environments, so plants had to adapt to obtain and conserve water. 
II. Sperm transfer was more challenging on land because there was no longer a fluid environment for sperm to travel in. Plants had to evolve specialized reproductive structures and strategies to transport sperm to the egg. 
III. Desiccation, or drying out, was a major threat to early land plants. They had to develop thick cuticles and other adaptations to retain water and prevent dehydration. 
IV. Animal predation was not a significant factor for the first land plants, as there were no large animals on land at that time.
