The development of pollen and seeds were key evolutionary advantages in plant adaptations to the terrestrial environment, because seeds can withstand harsh environmental conditions, many animals will eat seeds, water is not needed for fertilization, or seeds can germinate many years later.

So the main benefit of pollen and seeds for adapting to the terrestrial environment is sea, and not just fertilization, but germination as well.
00:30
Prior to seed and pollen plants, fertilization and germination required water.
00:40
So before pollen, there were flage -related sperm that would swim through the water to get to the egg cell.
00:48
And pollen means that they are no longer reliant on that.
00:52
So if you look at a moss, it can only reproduce if its surface is wet.
00:56
But a seeded plant doesn't have to do that.

They have pollen...
