Today we're going to plant a seed, but before that we're going to talk about the sexual reproduction in plants.
00:00:03
First step, we have pollination. It consists in the pollen of a flower goes transported to the pistil of another flower.
00:00:11
They can transport it with animals, wind, or water.
00:00:27
Next step is fertilization. It consists when the ovule fertilizes it and it sits inside the ovary.
00:00:32
Then is the sex formation. It's when the fertilized ovule from an embryo which becomes a sex.
00:00:44
The ovary changes size and shape and becomes a fruit.
00:00:56
Finally, it's fermentation. The fruit and the seed are away from parent plants and come into compounds with the soil.
00:01:05
When the seed is exhausted, it recedes the sun to water and light, it herminates and grows into a new plant.
00:01:23

Kids, we are going to plant peas.
00:01:45
To do so, we're going to put the seeds in water for two or three hours.
00:02:31
During that, we're going to do a hole in the soil.
00:02:38
When the two or three hours pass, we're going to put the seeds in the hole we made.
00:02:44
and we cover it with the soil and then we have to put plenty of water.
00:02:55
In five months the plants will grow very tall.
00:03:06
Bye!
