 In our previous videos we discussed about the male reproductive part of a flower which is this part that has the antholobes and the long filamentous stamen and we also discussed that the male gamete that is the pollen are formed inside the antholobes and we also saw how these pollen are released outside in the environment. Now what happens after they are released? After they are released they fall on the female reproductive part of flower via different means they fall on to the female reproductive part of flower which is this one. The means can be weaned it can be insects well that is again a different story but once they fall on the female part fertilization take place. Now before we discuss in detail about fertilization and what all happens in fertilization we need to first understand the female part okay so in this video we are going to talk in detail about the female reproductive part of a flower and we call that part the pistol. Well when I was in my fifth or sixth grade and I saw the picture of this male and female part of flower in my textbook for the first time I thought that this female part quite resembled the water pitcher or the water jug what do you think well to help your imagination how about I modify the pistol a little bit what do you think now well apart from the look this jar and the pistol has some other similarities as well we can derive some more similarities and let me tell you how see if you want to pour water into this jug you will do it from the upper top right from the mouth of the jar in the same way when the pollen tube from the pollen enters this pistol it will do it from the upper top portion this swollen portion that you see the pollen will enter its pollen tube from the upper top portion. Now the water will rush through this long stylish neck that it has even here the pollen will move down this long stylish neck that it has and then the water will be stored here in the jug and in case of the pollen tube it will do the fertilization somewhere here in the broad swollen area well you need not worry about where this pollen tube has come from how did it just develop from the pollen because we will have a complete different video on it but for now just remember that the pollen enters from the top through its pollen tube and goes all the way down to this broad area okay and again if you are wondering why is she calling this long slender area stylish well this is because this area is has got a special name it is called style and that is the reason I was calling it stylish okay now the other parts of the pistol has also got specific names this upper area well let me remove the jar like shape of pistol there you go now this upper area is called stigma stigma now the stigma secretes some sticky substances to which the pollen sticks now from stickiness try remembering stigma and this broad area down at the bottom it consists of the eggs or it holds the egg or the female gamut and this swollen area is called ovary this is the ovary of the pistol well this is all about how the pistol or the female reproductive part looks from the outside now we also need to look what is on the inside of the pistol so let's zoom in to the inner side of the pistol now if you have a closer look at this ovary area you will see that there are small small lobe like structure attached to a stalk like thing these small small lobes are nothing but I like to call them the homes in which the female gamut will start growing and this lobules or the lobes are called ovule and it has also got a fancy name called mega sporengium now sporengium means the area or the place which will develop into a spore in this case the female spore and it is called mega which means big because it is bigger than the male spores which are called micro spores and they grow in micro sporengium we have already discussed about it in our previous videos and since the ovule is the area where the female gamut develops the pollen tube from the pollen has to reach all the way down to the ovule so that fertilization can take place now to understand the fertilization better and to understand where exactly the fusion between the pollen tube and the ovule is taking place we need to understand the structure of the ovule in detail right so let us now zoom in to the ovary and we will look into just one of the ovule and an ovule is made up of a mass of cell which is called the new cellus this word new cellus is derived from the word nucleus and they have named it so because I assume as the nucleus is the center or the core part of an atom in the same way the new celler cells forms the core part of an ovule and they are so important because one of the cell from these new cell cells grow and develop into a female gamut or female spore and as these are so important cells nature has given it a special protecting coat which is called the intake humans here I have shown two layers of covering or intake humans but some of you will has just one single layer so this intake humans are nothing but covers they are covers that codes the new cell or cells but if you can observe closely you will see that a small portion of the new cell or cells or the new cell or cell mass is left uncovered now can you guess why okay let me tell you it is left uncovered so that the pollen tube from the pollen can come and reach the female gamut as one of the cell will grow into a female gamut right so this area is left for the pollen tube to easily come and interact with the female gamut and the small area that is left uncovered is called micro pile microman small and pile comes from a Greek word which means gate so this is like a small gate that allows the pollen tube to reach the new cell or cells or we can say to reach the female gamut now the area in the new cell is which is extreme opposite of the micro pile is given a specific name called Chalaza so Chalaza is nothing but the bang opposite end of micro pile now this new cell or cell mass with the covering cannot just float inside an ovary right it has to be attached to the walls of the ovary somewhere so this attachment is done by a stock like thing which is named funical and this funical and the ovary meets at a region called placenta and also the area where the funical meets the integuments we call it the healer now if you're wondering oh my god there are so many new terms to remember then let me tell you that these are all words from the Greek and Latin origin and that's why we we find it very difficult so should we remember these names well just for the sake of exams we should but otherwise it is okay if we don't remember all these terms all right so this is all about the structure of the ovule well now if you're thinking that hey this looks like an easy diagram it is so simple but this is not the one that we see in our textbooks the one that we see in our textbooks looks something like this one well this is exactly the same as this ovule just placed upside down and therefore it is called ananthropus ananthropus ovule which means upside down and this is the most common type of ovule found and therefore we get this image in most of the books okay now let us compare both the ovules for better understanding so this inner circle that you see here is the female gamut and we have not made the female gamut here yet but it will be formed from one of these new cellars cells so if we ignore this female gamut here this entire part will be the new cellars right so let us give it the same color this is the new cellars and as you can see the new cellars has two coverings here it will also have two coverings so these two things that you see are the integuments and the portion which is left uncovered by the integument is called the micropile so this is the micropile end and the portion which is bang opposite to micropile will be the chelaza end right so let us label them as well and now as this ovule is placed upside down this funicle and the placenta will be will be somewhere on the top right so if we consider this to be the placenta the portion that is attaching the placenta with the integuments will be called the funicle right so this is the funicle now can you guess where will be the helum the helum is the area that is connecting the funicle and the integument so it will be somewhere here and this is it these are all the different parts of a typical ovule these are all the different parts that you need to know and in our future video we will talk about how the cells of the new cellars divide and form female gamuts but before we end the video here I would like to leave you with an unlabeled diagram of an ovule how about you pause the video and try and label different parts
