Selective plant
There are about 23,000 species in the world, ranging from tropical rain forests to polar tundra, all over the globe except the desert and the oceans. The body of the gypsophila, which we commonly see, belongs to the metamorphic generation as gametophy, and the nuclear image is n. In other words, it is a generation that makes a spouse, and it corresponds to a progeny of a fern, a backpack of a seed plant and a pollen tube. The spawner is a flask with a long neck, in which one oocyte is formed. On the other hand, the long period is a bag-shaped or ball-shaped bag with a bag, and a large number of sperm are produced therein. When the sperm that swim with two flagella touch the egg cells of the genitalia, the fertilization takes place there. The fertilized eggs repetitiously divide in the spawning period to form embryoid bodies. Then, the sporophyll grows while absorbing nutrients from the gametophyte, but in childhood the sporophyte itself also has some photosynthesis. Therefore, it can be said that the sporophyll is antipyretic to the gametophyte.
