0 123456789101112131415 Science : Ch 08 – How do Organisms Reproduce This test is designed based on NCERT Syllabus for Class 10 Topics : How do Organisms Reproduce Each time random 15 questions will be displaced So retake the quiz till you have mastered all the questions 1 / 15 Offspring produced by asexual method of reproduction have more similarity among themselves because: Asexual reproduction involves only one parent Asexual reproduction does not involve gametes Asexual reproduction occurs before sexual reproduction Asexual reproduction occurs after sexual reproduction only one parent is involved in the Asexual reproduction ,there is no fusion of male and female gamates. only one parent is involved in the Asexual reproduction ,there is no fusion of male and female gamates. 2 / 15 Fertilisation is the process of Transfer of male gamete to female gamete Fusion of nuclei of male and female gamete. Adhesion of male and female reproductive organs The formation of gametes by a reproductive organ formation of single cell during sexual reproduction by fusion of nuclei of male and female gamates. formation of single cell during sexual reproduction by fusion of nuclei of male and female gamates. 3 / 15 The number of chromosomes in parents and offsprings of a particular species remains constant due to: Halving of chromosomes during gamete formation Doubling of chromosomes after zygote formation Halving of chromosomes during gamete formation Doubling of chromosomes after gamete formation Halving of chromosomes after gamate formation Reduction division (meiosis) takes place during gamete formation. Reduction division (meiosis) takes place during gamete formation. 4 / 15 The characteristics transmitted from parents to ofspring are present in Cytoplasm Ribosome Golgi bodies Genes Genes are carriers of genetic information and are responsible for the transmission of characteristics from parents to offspring's. Genes are carriers of genetic information and are responsible for the transmission of characteristics from parents to offspring's. 5 / 15 Factors responsible for the rapid spread of bread mould on slices of bread are: Large number of spores Availability of moisture and nutrients in the bread Presence of tubular branched hyphae Formation of round shaped sporangia 1 2 1 And 2 1 and 3 Bread mould prefers damp/warm conditions with ample nutrient supply, on which air-borne spores land and germinate. Bread mould prefers damp/warm conditions with ample nutrient supply, on which air-borne spores land and germinate. 6 / 15 Slides of binary fission in Amoeba and budding in yeast were given for observa group of students. Some of the observations reported by the group are given below: Cytokinesis was observed in the yeast cell. A chain of buds were observed in Amoeba. Single cell of Amoeba and single cell of yeast were undergoing binary fission and budding respectively Elongated nucleus was dividing to form two daughter nuclei in Amoeba 3 and 4 2 and 3 3 1 and 4 7 / 15 Example of unisexual fowers. Papaya Mustard Hibiscus Rose Unisexual flowers contains only one reproductive organ, either male or female. Unisexual flowers contains only one reproductive organ, either male or female. 8 / 15 What is the mode of asexual reproduction in hydra? Fragmentation Binary Fission Spore Formation Regeneration Or Budding 9 / 15 What is the mode of asexual reproduction in planaria? Spore Formation Fragmentation Binary Fission Regeneration 10 / 15 What is the mode of asexual reproduction in Rhizopus Spore Formation Fragmentation Budding Binary Fission 11 / 15 which of the following is a viral STD? Gonorrhoea Syphilis. Both 1 & 2 HIV-Aids And Warts 12 / 15 What do you understand by Puberty? The age at which the reproductive organs of boys and girls become non functional. The age at which the reproductive organs of boys and girls become functional. It is a process of fertilisation in boys and girls. None of these 13 / 15 A pair of long convoluted tubes that carry ova or eggs from the ovary to the uterus is known as Tubectomy Callopian Tube Fallopian Tube All Of These 14 / 15 A surgical method of Blocking vas deferens to prevent pregnancy is done for Females Males Both 1 & 2 None Of These 15 / 15 Total number of chromosomes present in human beings are 46 23 24 48 Your score is 0% Restart quiz
