You can find us in almost every social media platforms. Each ascospore is surrounded by a thick wall. They are dispersed by wind from one place to another. 1. Content Guidelines 2. Asexual reproduction  takes place by the formation of endospores during unfavourable conditions. Choose the correct answer: Question 1. Pollination is the process of fusion of male and female gametes. This four haploid nuclei changes into Ascospores. Question 1. Haplobiontic lifecycle is found in Yeast(Schizosaccharomyces endosporous).In this lifecycle, the haploid phase is more represented than the diploid phase. 9. Each fragment then grows individually like the mother mycelium. Maple seed is dispersed by explosion mechanism. Fruits are developed from the ripened ovary. When yeast are under environmentally stressful conditions a form of meiosis takes place, known as sporulation. Maple seed is dispersed by explosion mechanism. Some diploid somatic cells can act as mother cell in which meiosis cell division takes place and four haploid nuclei are formed. Fruits are developed from the ripened ovary. It is a network of social relationships which cannot see or touched. This type of reproduction probably takes place in adverse conditions, especially when there is scarcity of nutrients and abundance of oxygen. At the same time the nucleus and cytoplasmic organelles divide. Add your answer and earn points. In this lifecycle, haploid and diploid phases are equally represented so, this lifecycle is called haploid diplobiontic lifecycle. Flow of energy and information through the cell. Fruits are developed from the ripened ovary. Maple seed is dispersed by explosion mechanism. In this lifecycle, the diploid phase is more represented than the haploid phase. Vegetative, 2. When bud enlarges in size their become large constriction between bud and parent cell due to which bud gets detached from parent cell and live as a new yeast cell. One of the nucleus with other cytoplasmic contain migrate towards the bud. Two individuals are needed for the sexual reproduction. Vegetative propagation in potato takes place by Two individuals are needed for the sexual reproduction. Asexual Reproduction: Asexual repro­duction takes place by unicellular, uninucleate, nonmotile spores, the conidia; formed on conidiophore (Fig. Bud takes nutrition from parent & grows in size upto maturity. It takes place in yeast in favourable conditions. This takes place by conjugation. The ascus wall bursts and the ascospores liberate « in the atmosphere. See answer s12345639 is waiting for your help. The nucleus of the mother cells divides amitotically and transfers to the daughter cell. Reproduction in Plants Class 7 MCQs Questions with Answers. You can refer to NCERT Solutions for Class 7 Science Chapter 12 Reproduction in Plants to revise the concepts in the syllabus effectively and improve your chances of securing high marks in your board exams. Around each nucleus the cytoplasm is deposited, they become walled and called the ascospores. 7. 8. 5. 5. 4.43). Fusion of gametangia takes place and a diploid zygote is formed. Reproduction in Plants Class 7 MCQs Questions with Answers. These spores are perennating bodies. Answers: 1. This is followed by the dissolution of intervening walls and nuclear fusion which takes place in the conjugation tube. A feature of reproduction that is common to Amoeba, Yeast and Spirogyra is that (a) they reproduce asexually (b) they are all unicellular (c) they reproduce only sexually (d) they are all multicellular.
