1 00:00:00,690 --> 00:00:08,609 Hello boys and girls, I hope you are all well at home. Today we're going to learn how plants with 2 00:00:08,609 --> 00:00:16,769 flower reproduce. To do so, the first thing we need to learn are the parts of a flower. 3 00:00:16,769 --> 00:00:26,530 This is a petal. If you look closely, you realize that a petal is just a modified leaf. 4 00:00:26,530 --> 00:00:39,600 and all petals together form the corolla yep okay if you look at the bottom of 5 00:00:39,600 --> 00:00:46,380 the picture you can see some small green leaves that protect the flower these are 6 00:00:46,380 --> 00:00:55,320 the sepons and all the sepons together form the calyx let's go back to the top 7 00:00:55,320 --> 00:01:10,340 the flower these are the stamens in stamens the pollen is produced finally 8 00:01:10,340 --> 00:01:21,560 we have the piston the piston is the female part it contains the ovary well 9 00:01:21,560 --> 00:01:28,159 now that we know the parts of the flower we can learn how plants with flower 10 00:01:28,159 --> 00:01:38,420 reproduce first the pollen is formed here in the stamen in the main part of 11 00:01:38,420 --> 00:01:46,879 the flower this pollen needs to reach the pistil of a different flower this 12 00:01:46,879 --> 00:01:55,680 can be done by the wind or insects that act as pollinators so let's pretend a 13 00:01:55,680 --> 00:02:05,079 bee comes to the flower to collect pollen to make honey here's the bee hello 14 00:02:05,079 --> 00:02:13,439 children so the bee comes to the flower to collect the pollen the bee gets the 15 00:02:13,439 --> 00:02:20,860 pollen the pollen gets stuck to the bee to the bees legs then the bee goes to a 16 00:02:20,860 --> 00:02:26,919 different flowers let's pretend now this is a different flower the bee goes to a 17 00:02:26,919 --> 00:02:36,159 different flower to collect more pollen well some of the pollen from the first 18 00:02:36,159 --> 00:02:44,180 flower you're going to fall into the second flower piston when a grain of 19 00:02:44,180 --> 00:02:55,180 pollen reaches the flowers pistil the ovary matures and turns into a fruit 20 00:02:55,180 --> 00:03:04,159 let's have a look at the development of a tomato they say in England a tomato to 21 00:03:04,159 --> 00:03:11,340 learn a little bit more about that well first the flower develops once the 22 00:03:11,340 --> 00:03:19,800 flower is ready the flower opens now bees or in this case bumble bees are 23 00:03:19,800 --> 00:03:27,000 going to pollinize the flower that means that some pollen is gonna travel from 24 00:03:27,000 --> 00:03:34,840 one flower piston into from one flower statement into a different flower piston 25 00:03:34,840 --> 00:03:44,680 what happens when the pollen gets to the different flower pistons well the 26 00:03:44,680 --> 00:03:50,460 petals are going to fall down because they're not needed anymore and inside 27 00:03:50,460 --> 00:03:57,840 the piston the fruit is going to develop you can still see the sepals are the 28 00:03:57,840 --> 00:04:02,020 sepals that were protecting the flower are still in this case protecting the 29 00:04:02,020 --> 00:04:11,259 the fruit the fruit is going to grow and grow and grow and when it's ready you're 30 00:04:11,259 --> 00:04:18,699 gonna change color it's gonna turn in this case from green to red well inside 31 00:04:18,699 --> 00:04:25,800 the fruit are the seeds and when one of these seeds falls on the ground it may 32 00:04:25,800 --> 00:04:30,639 germinate and a new plant grows so let's pretend that one of these seeds from 33 00:04:30,639 --> 00:04:36,939 tomato falls to the ground and then it germinates mean that the roots are going 34 00:04:36,939 --> 00:04:42,040 to start to grow under the ground and the stem and the flower and the leaves 35 00:04:42,040 --> 00:04:49,819 are gonna grow above the ground that's how a new plant grows and that's how 36 00:04:49,819 --> 00:04:56,019 plants reproduce so I hope that after this video you understand a little bit 37 00:04:56,019 --> 00:05:03,040 better how plants with flower reproduce so that's all for today stay home and 38 00:05:03,040 --> 00:05:07,019 stay safe bye bye for now
