This question is asking us about pollinators and which group of plants need animal pollinators.
00:09
And the answer is c.
00:12
And c is the angiosperms.
00:14
And remember that angiosperms is another word for flowering plants.
00:20
So if you think of a plant with a flower, whether it's an orchid or a daisy or an apple tree, right? those are all angiosperms.
00:30
They all make flowers.
00:32
And what the pollinators do is move pollen around.
00:37
So they move pollen from the male parts of a flower.
00:46
So move pollen from the anthers to the female parts of the flower.
00:59
And those female parts of the flower are the stigmas.
01:02
The pollen moves from the anthers to the stigma, which is the top of the carpal.
01:12
Now, a couple sort of notes about this.
01:19
One is that many angiosperms use wind to move their pollen.
01:24
So many, many trees, grasses, for example, also use wind to move their pollen...
