We are being asked about the sexual reproduction in bryophytes.
00:09
And shown up here on the left -hand side is a bryophyte.
00:16
It is a plant, and bryophytes are actually the first plants to colonize land.
00:23
And shown in the center here is a diagram of the bryophyte plant.
00:29
And the antheridium and the archegonium are the anatomical parts of this plant that produce the sperm and the eggs.
00:40
They are located on different areas of the leaf of the plant.
00:48
And right here, you have a basically blow -up of the antheridium, and right next to it, you have a blow -up of the antheridium, the archagonium.
01:02
So in order for sexual reproduction to happen, the sperm must travel from the antheridium to the archagonium right here.
01:17
And the way that the sperm travels from the anthoredium to the archegonium is through a film of moisture that is on the leaf and the sperm swims all the way to antheridium...
