Hello students in this question we have to label this given diagram of a flower so let's start this structure this is enter and this structure this is filament and the combinedly known as stem and this structure is known as stigma and this structure this is known as style and this structure this is ovary and in common they are known as carpal.
00:57
This is sepal and this is the ovary sorry ovule and this structure is receptacle.
01:21
So this is the labeling of the given diagram.
01:25
Now as we know that big showy flowers they help attract the pollinators so we have to tell why do we think grasses like big showy flowers.
01:36
So let's answer this question.
01:41
The grasses, they are wind pollinated and a single flower hint of an average grass can produce 10 million pollen grains and wind pollinated plants usually grow together to increase the likelihood of pollination and grasses are wind pollinated and a single flower had as 10 millions as i told you before so therefore the wind pollinated plant usually grow closely together now this is why the grasses do not have a big showy flowers because they grow together now let's see the answer for the next question which is the pollen where we have to see the example of pine pollen and lily pollen and tell what feeder of feathers could we use to tell pollen, sorry, pine pollen from the lily pollen.
03:17
So the answer is the structure of lily pollen under the microscope.
03:31
We can observe the lily sea family.
03:51
Pollen, it looked like wheat grain and the structure and galile present at the top to bottom of the pollen grain and its outer surface is rough and both and of the pollen are straightly trapping let's see in the diagram like it is something like the wheat this is the top to bottom canal which is present in the lily and this is the rough structure of the lily gray or spore sorry pollen so this is lily under the microscope.
04:55
Now let's see the structure of pine under the microscope, pine pollen.
05:08
So the pine pollen, it looked different from the lily pollen.
05:13
The main circular body is present and two sequailles, which is air sac, wing -like structure.
05:32
This come out of it and this pollen found male cones and of the pine.
05:39
So the structure it looked like this.
05:43
This is a circular body and these are the wing like structure to sikai.
05:53
This is this looks like something this.
05:56
This is a pine pollen under the microscope.
06:12
Next we have to talk about fruits and seeds where we have to tell the seed dispersal in the ngos sperm and they're mature.
06:29
And also we have to tell the types of fruits and seeds.
06:34
So let's start with the first which is sperm.
06:38
This is the greatest part of the organic product shave from the repository under the bloom.
07:05
We can take examples beer and apple.
07:12
And next number two, it is droop.
07:18
It has a meaty food which are grown from ground with a single seed with a hard endocard.
07:39
We can take examples, peaches, coconut and third one we will take berry.
07:58
So this has numerous seeds.
08:06
With example, it is tomato and cucumber but not the strawberries.
08:18
And fourth is total fruit which is created from one blusum with numerous pistols.
08:42
So example is strawberries and number five it is legume.
08:57
So the legumes they split around the different sides...
