Reproduction in Organisms MCQ Questions Full Syllabus Biology with Answers
IMPORTANT POINTS
Reproduction is biological process in which organism give rise to offspring similar to itself. In living orgamism there are two types of reproduction. (1) Asexual reproduction and (2) Sexual reproduction.
In a sexual reproduction single parent is involved and capable of producing offspring . Fission, sporulation, budding and fragmenation are the comman modes of a sexual reproduction seen in animals and plants.
Zoospore, conidia etc are the comman a sexual structures formed in several algae and fungi.
In flowering plants vegetative reproduction, are natural and artificial. In natural method the development of new plant takes place under suitable environmental conditions from some organ like stem,leaf,root or even flower of the mother plant.runners,offsets,stolons and suckers are the common other natural methods of reproduction seen in angiosperms.The artificial method of propagation are cutting,layering and grafting. Sexual reproductin involves formation and fusion of gametes.it is a complex and slow process as compared to a sexual reproduction.Events of sexual reproduction may be categorized into the pre-fertilization, fertilization and post-fertilzation events.
Pre-fertilization events of sexual reproduction are found prior to the fusion of gametes. The two main pre-fertilization events are gametogenesis and gamete transfer. Gametes are always haploid and homogametes or heterogametes. After formation, the male and female gametes are brought together to facilitiate fertilization. The fusion of two similar or disssimilar gametes is called syngamy and its result in Formation of diploid zygote is formed, this process is known as fertilization. It is external or internal.
The formation of zygote and the process of development of embryo are called post fertilization events. Zygote is the vital link that ensures continuity of species between organisms of one generation and the next. Embryogenesis is the process of development of embryo from the zygote during embryogenesis zygote undergoes cell division and cell differentiation cell divisions increase the number of cells while differentiation helps group of cells to under go certain modification to form specialized tisse and organs to form an organism.
