Sexual reproduction of angiospermic plant |
| Answer» Fertilization is the actual reproductive process where the sperm nuclei fuse with the ovary to form the zygote. In a simple way, a successful pollination leads to fertilization.After pollination, each pollen grain on the stigma sends out a tiny threadlike tube. The tube grows down, penetrates the stigma, passes through the style and enters the ovule through an opening called microphyle. In the microphyle it releases two male gametes in the embryo sac. One male gamete fuses with egg cell and the second fuses with the two polar nuclei.The fusion of one male gamete with the egg cell is called syngamy or true fertilization while the fusion of second male gamete with two polar nuclei is called triple fusion. Syngamy along with the triple fusion is called double fertilization. Double fertilization is a characteristic feature of flowering plants or angiosperms | |

How is a seed formed. What is it\'s significance? |
| Answer» Seed is a reproducing unit of a flowering plant. A seed consists of three parts. These are as follows:\tSeed coat – Seed is enclosed in a protective layer which is called a seed coat.\tEmbryo – It is a young miniature structure of the plant.\tCotyledon – It is used to store the starchy food and proteins for the embryo.Significance of Seed\tSeed plants do not require water for pollination and fertilization. Hence seed formation is more dependable.\tSeeds have adaptive characteristics of the new environment, which is beneficial for seed dispersal and colonization\tSeeds can carry a number of variations through sexual reproduction.\tThey can be stored for future use.\tThey can reserve food for nourishing the young plant.\xa0 | |

What is mechanism of soap |
| Answer» The dirt present on clothes is organic in nature and insoluble in water. Therefore, it cannot be removed by only washing with water. When soap is dissolved in water, its hydrophobic ends attach themselves to the dirt and remove it from the cloth. Then, the molecules of soap arrange themselves in micelle formation and trap the dirt at the centre of the cluster. These micelles remain suspended in the water. Hence, the dust particles are easily rinsed away by water. | |

What are all the importance of variations? |
| Answer» In nature, variations occur during sexual reproduction. If this variation is beneficial to the species, it is selected and remains in the population. This is because the variant species are more adapted. Therefore, they can survive better and reproduce to pass the genes to the offsprings.Variations are very important for organisms to survive because if there were no variations among living organisms there would have been no evolution or change and natural conditions do not remain constant they keep on changing. If variations stops then we would not be able to adapt to the changing conditions and can prove catastrophic to us. | |
