Class 10th Science Chapter 7 Reproduction

HOW DO ORAGANISMS REPRODUCE CHAPTER --7 Reproduction :- Reproduction is a fundamental biological process of producine young ones or mention its role during offspring, which are identical to their parents. Fertilization:- Fertilization is the fusion of male and haploid female gametes (egg and sperm) resulting in the formation of a diploid zygote Q.1What is pollination? Ans. The process by which plant fallen is transferred from male reproductive organ to the female reproductive organs to form seeds is called pollination .2 what is cross pollination or allogamy? Ans. It is the process of transfer of pollen grains from the anther of a flower to stigma of another flower, of same or different plant, of the same or related -closely species. Q.3 Define grafting? Ans. In grafting, one part of plant is inserted into another plant in away that both of them will unite and grow together as a single plant. Q.4 How does binary fission differ from multiple fission? Ans. In binary fission, a single cell divided into two equal halves. Amoeba and bacteria dividede by binary. In multiple fission a single cell divided into many daughter cells such that plasmodium and malarial Q.5 Define self pollination? Ans. the pollen grains from the anther of the flower trapsfer to the stigma of the same flower then this process is called self pollination. Q.6 what is regeneration? Ans, Regeneration is a process in which whole new organisms can be produced from there cut body parts. Example--planaria and hydra Q.7 what happens if fallopian tube is blocked? Ans. If fallopian tube is blocked, the egg will not be able to reach the uterus in such a case, fertilization will not take place Q.8 where is zygote located in the flower after fertilization? Ans. Zygote is formed by the fusion of male and female gametes it is present in the ovule .ovule is present inside the ovary of a carpel. pregnancy. Ans. Placenta is a special tissue developed between an embryo and uterine wall during pregnancy. Placenta roll during pregnancy- 1. Placenta firmly attaches the embryo with uterine wall. 2. Embryo gates its Oxygen and nutrients requirements from the uterus through placenta. 3. Waste produce in embryo are transferred to. the blood supply of mother through placenta. Q.10 how does embryo gets nourishment inside the mother's body? Ans. Embryo gets nourisliment inside the mother's body from the blood of the mother. For this purpose, specific tissuelnon as placenta is developed which provide glucose, Oxygen and other materials required to the embryo from the mother's body. Q.11 Why is reproduction essential in human being? Ans. It is a biological process through which living organisms produce offspring similar to them. Reproduction insures the continuity of various species on the earth. If the organisms would not reproduce the species to which the belong would extinct once they are dead. Q.12 How is the process of pollination different Q.14 What is the importance of DNA copying in reproduction? Ans.. •It maintains the characteristics of spe.#Class10Science #Reproduction #ScienceInHindi #Class10Biology #Chapter7 अतिरिक्त Hashtags #HowDoOrganismsReproduce #Class10ScienceChapter7 #NCERTScience #CBSEClass10 #MPBoardClass10 #Class10ScienceHindi #ReproductionInHindi #ScienceChapter7 #BiologyInHindi #BoardExam2027 #Class10thScience #NCERTClass10 #HindiMedium #ScienceLecture #Class10ExamPreparation वीडियो के लिए सुझाए गए 5 मुख्य हैशटैग: #Class10Science #Reproduction #ScienceInHindi #Class10Biology #MPBoardClass10📚 Class 10 Science Chapter 7 Reproduction in Hindi | जीव जनन कैसे करते हैं? इस वीडियो में कक्षा 10वीं विज्ञान के अध्याय 7 (Chapter 7 – How Do Organisms Reproduce?) को आसान हिंदी भाषा में समझाया गया है। यह वीडियो NCERT Science, MP Board, CBSE Board और अन्य राज्य बोर्ड के विद्यार्थियों के लिए उपयोगी है। इस अध्याय में जीवों में जनन की प्रक्रिया, लैंगिक एवं अलैंगिक जनन और मानव जनन से संबंधित प्रमुख अवधारणाओं को समझने में मदद मिलेगी। 📖 इस वीडियो में पढ़ें: ✅ Reproduction in Organisms ✅ Asexual Reproduction (अलैंगिक जनन) ✅ Fission और Budding ✅ Fragmentation और Regeneration ✅ Vegetative Propagation ✅ Sexual Reproduction (लैंगिक जनन) ✅ Reproduction in Human Beings ✅ Male और Female Reproductive Systems ✅ Reproductive Health ✅ NCERT Important Questions ✅ Class 10 Science Board Exam Preparation 🎯 यह वीडियो किन विद्यार्थियों के लिए उपयोगी है? ✔️ Class 10 Science Students ✔️ CBSE Board Exam 2027 ✔️ MP Board Class 10 ✔️ NCERT Science Chapter 7 ✔️ हिंदी माध्यम के विद्यार्थी ✔️ Science Revision और Exam Preparation 📌 अगर आप कक्षा 10 विज्ञान के सभी अध्यायों की तैयारी करना चाहते हैं, तो चैनल को Subscribe करें और नई वीडियो के लिए Bell Icon दबाएँ। 👍 वीडियो उपयोगी लगे तो Like करें और अपने दोस्तों के साथ Share करें। #Class10Science #Reproduction #ScienceInHindi d
