Hence, both the processes are said to be interlinked. Asexual reproduction is known to create the copies of an organism having the same genetic material . Asexual reproduction is common among single-celled organisms, and in plants and animals with relatively simple organisations. 2023 New Visions for Public Schoolsbuilt by blenderbox. In this lab, students examine the intricate structures that compose a flower. This method of asexual reproduction is found in animals like planaria, earthworm, starfish etc. The ovule develops tough coat and gradually gets converted into a seed. (b) If both assertion and reason are true but reason is not the correct explanation of assertion. Question 10. Reproduction in organisms is of two types asexual and sexual reproduction. In the sexual mode of reproduction in organisms, a new offspring is produced by the participation of two parents of the opposite sex, such as the male and female. One key area where these differences are observable is in their method of gamete production and their fertilization methods. During spore formation, the organisms form knob-like structures called a sporangium. NCERT Solutions for Class 10 Science Chapter 8 How do Organisms Reproduce (i) Sexual reproduction takes place in multicellular organisms. In this type, rapid population growth is observed only if there is a proper environmental condition. Many plants reproduce naturally as well as artificially by vegetative propagation and the offspring produced are genetically identical. The gametes must be brought in contact with each other to achieve fertilization. In sexual reproduction, the genetic material of two individuals from the same species combines to produce genetically-different offspring; this ensures mixing of the gene pool of the species.that's why. The process of meiosis results in the production of eggs and sperm which each contain half of the genetic information. Sexual reproduction is a natural way of reproduction andtakes place in all multicellular organisms. Animal Reproductive Strategies | Organismal Biology - gatech.edu 1. Comparative Reproduction | New Visions - Science When the conditions are favourable, they begin to grow. b) Spermatogenesis: In this process, the spermatogonium, a stem cell is deposited at the time of birth and forms sperms in adolescence. Reproduction - Reproduction of organisms | Britannica Reproduction (or procreation or breeding) is the biological process by which new individual organisms - "offspring" - are produced from their "parent" or parents.Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction.There are two forms of reproduction: asexual and sexual. States an appropriate hypothesis, Write routinely over extended time frames (time for reflection and revision) and shorter time frames (a single sitting or a day or two) for a range of discipline-specific tasks, purposes, and audiences. In Protists and Monerans, the organism or the parent cell divides by mitosis into two to give rise to new individuals (Figure1).
