- [00:00:03.080]It's important to understand the parts of a flower
- [00:00:05.600]when talking about how seeds are made
- [00:00:08.250]during sexual reproduction.
- [00:00:09.730]So let's use this flower as an example,
- [00:00:13.000]as we go over the different flower structures,
- [00:00:15.450]and learn to be able to tell the difference
- [00:00:17.450]between the male and the female structures of the flower.
- [00:00:22.560]So we're gonna start by identifying
- [00:00:24.540]kinda the outside structures here.
- [00:00:25.890]So you see the petals.
- [00:00:27.740]And then after we remove the petals
- [00:00:29.370]from this example flower,
- [00:00:31.570]then we're gonna show the sepals,
- [00:00:33.150]and the sepals are gonna be more of just a protective layer
- [00:00:35.780]that protects the flower.
- [00:00:39.690]Now, keep in mind that not all flowers
- [00:00:41.220]are going to look exactly like this.
- [00:00:43.210]But when sexual reproduction happens with a flower,
- [00:00:47.400]these are gonna be the main parts,
- [00:00:49.550]that we're gonna talk about next,
- [00:00:50.780]that are gonna be important in that sexual reproduction.
- [00:00:53.830]So the first aspect that we want to talk about
- [00:00:56.510]is the stamen, which makes up the male
- [00:00:58.980]reproductive structures of a flower,
- [00:01:01.650]and the stamen is gonna be made up of the anther
- [00:01:04.210]and the filament.
- [00:01:05.570]And the anther is going to contain the pollen.
- [00:01:12.140]The female reproductive structure is called the pistil,
- [00:01:15.120]and the pistil is gonna be made up of the stigma,
- [00:01:17.530]the style, and the ovary.
- [00:01:19.780]And the stigma is gonna be the location
- [00:01:21.750]where the pollen will land
- [00:01:23.780]in order for fertilization to happen.
- [00:01:28.830]If we take a little bit of a closer look into the ovary,
- [00:01:31.390]we'll see that the ovary is also made up of ovules,
- [00:01:33.963]and the ovules are another way of saying the eggs.
- [00:01:42.210]So now that you've had a chance
- [00:01:43.250]to see the different structures of a flower,
- [00:01:45.740]why don't you use the animation to be able
- [00:01:47.660]to test your knowledge on the different structures?
