Pre-lab 5: Introduction to Plant Diversity II Question 1. In contrast to Bryophytes, Lycophytes, and Monilophytes what specific advantage does pollen provide to seed plants in terms of their reproductive biology? Pollen is advantageous because it does not need water for the male cell to reach the female cell. Instead, pollinators transfer the different cells. Question 2. In contrast to Bryophytes, Lycophytes, and Monilophytes what specific advantage do seeds provide to seed plants in terms...
