How do Organisms Reproduce Class 10 all Definition
All our Dear CBSE Champs, Here we Net Ex. have included How do Organisms Reproduce Class 10 all Definition. All the given definition are important for this year board exam.
- Reproduction
Reproduction can be defined as generation or production of new progeny from itself. There are 2 different types of reproduction such as asexual method of reproduction and sexual method of reproduction
- Asexual method of reproduction
The asexual reproduction is one of the simplest type of reproduction occurs in lower living organisms. In asexual reproduction there is involvement of gametes, no fusion of gametes, it is uniparental. They have ability to reproduce small sized and large number of progenies in shorter period of time. For example : Bacteria.
- Budding
In budding there is unequal division of the parent body, that is new outgrowth arises from animal body, it can be seen in both prokaryotes and eukaryotes. The major example of budding is yeast.By this process budding occurs. It is basically the outgrowth from parent or specifically yeast. Therefore the division and reproduction occurs. The asymmetrical division of cell will start from particular site on parent’s cell.
- Spore formation
Spore formation also called as sporogenesis, in which spores released from the living organism body such as single celled organism for reproduction, this spores can be transmitted through air, water and insect medium. More appropriate example of spore formation is Rhizopus.
- Regeneration
Regeneration can be defined as generation or formation of a new organ from the lost or damaged part of the body. Such type of organism have ability to regenerate their organs. For example : Planaria.
- Fragmentation
fragmentation can be considered as the example of sexual reproduction. The process of fragmentation can form entire organism. The fragmentation can also occur in broken parts to form the part of the body. For example : Spirogyra
- Sexual reproduction in flowering plants
It can be termed as sexual reproduction occurs when male gamete fuses with the female gamete that is fusion of gametes in which two parents are involved it leads to formation of gametes
The sexual reproduction takes place in flowering plants. Flower is the reproductive organ for sexual reproduction.Sexual reproduction in flowering plant occurs in two generations such as gametophytic generations and sporophytic generation.
- Reproduction in human beings :In humans the reproduction is most complex type of reproduction contains both the sexes. In both sexes separate male reproductive organ and female reproductive organ and systems are present. In case of male testis, seminal vesicle, prostrate gland, epididymis, spermatic cord, ejaculatory duct and urethra presentIn case of female ovaries, hormones, uterine tube, uterus, vulva and vagina are present.
- Spermatogenesis:The process of formation of sperm called spermatogenesis. Each sperm is about 60 ꭒm in length. The sperm is a sex cell therefore its division takes place through meiosis. Meiosis is the process for the division of germ cells. The sperm contains mitochondria, which gives energy for the mobility of sperm.
- Oogenesis: The production of female gamete or egg in the ovaries called oogenesis. The spermatogenesis process differs from oogenesis in terms of production of gametes. The male gamete (sperm) produced at the stage of puberty where the female gametes produced before the birth.
