Difference Between Sexual And Asexual Reproduction

The process through which living beings create other organisms of the same species to which they transmit their genetic information is called reproduction. there are two types of reproduction: sexual and asexual; each one in turn presents various strategies. Homo-sexual reproduction is different from sexuality, while the latter requires two distinct cells of different sexes, i.e., to form gametes through the process of miosis. Organisms created from sexual reproduction are genetically different from their parents because they are a mixture of genetic information in two gametes. This is a slower approach but adapts to more variable environments. This article will help you to find the main differences between sexual and asexual reproduction. The basic difference b/w them is that asexual reproduction takes place in lower animals and plants, fungi, and bacteria. while sexual reproduction occurs in almost all animals, plants, fungi, protists, and bacteria.

What is Sexual Reproduction?

Sexual reproduction is a kind of reproduction in which two individuals of different sex of the same species participate. This reproduction implies:

  • the production of haploid-sex cells;
  • the fertilization or fusion of two sex cells to form a diploid cell called a zygote.
  • Vertebrate animals can only reproduce sexually.

Types of Sexual Reproduction In Animals

There are three main types of sexual reproduction that occur in animals listed below:

  • Autogamy
  • External fertilization
  • Internal fertilization

Autogamy

  • A kind of sexual reproduction where the same individual presents both female and male gametes refers to autogamy.
  • These individuals are also called hermaphrodites, they have the reproductive system of both sexes.
  • This type of reproduction is achieved in worms.

External fertilization

  • It implies that the male and female games and sperms are outside the body of organisms.
  • External fertilization is carried out in a liquid medium in most aquatic species such as fish or in amphibians, such as the frog.

Internal fertilization

  • This process occurs within the body of one of the individuals, generally the female of the species, after the male deposits the sperm into the female reproductive system.
  • This is the fertilization of birds and mammals, mainly.

Types of Sexual Reproduction In Plants

Sexual Reproduction In Flowers

  • Flowers: angiosperms represent 85 – 90% of the plant species on Earth. The most representative evolutionary characteristic of angiosperms is the flowers, which contain the reproductive organs of the plant.
  • The sexual reproduction of plants runs with the landing of the pollen grain, that carries the male gametes, on the surface of the stigma, the entrance for the female gamete.
  • The fusion of the gametes initiates the development of the seed within the fruit.

Sexual Reproduction In Gymnosperms (Seeds Without Flowers)

  • Gymnosperms group conifers: pines and other related plants.
  • They do not have flowers as such, while structures called cones, that produce both male and female spores.

What is Asexual Reproduction?

Asexual reproduction is any form of reproduction where an individual produces an exact copy of himself. In this type of reproduction:

  • No formation of gametes or sex cells occurs
  • No fertilization or fusion of gametes occurs.

Where does asexual reproduction take place?

Asexual reproduction occurs in:

  • bacteria
  • archaea
  • protozoa
  • fungi
  • plants
  • in some animals.

Types of Asexual Reproduction

There are different reproductive kinds that do not involve the participation of two individuals of different sex. Let’s check and discuss the various types of asexual reproduction.

  • Vegetative Multiplication

It is the most particular method of asexual reproduction in plants. It consists of the formation of new beings from the development of certain plant structures, such as roots, bulbs, trunks, and leaves.

It occurs in most vegetative plants, for example, garlic, strawberry, and sweet potato.

  • Binary Fission

Binary fission is the process through which prokaryotes (bacteria and archaea) and some protozoa produce new individuals that are genetically identical to the parent organism. In this case, the genetic material is duplicated and then separated into two daughter cells with the same genetic identity.

In amoebas, paramecia, and planarians, the cell divides and produces new individuals.

  • Gemmation

Budding is a kind of asexual reproduction where the organism produces one or more buds or buds, which grow and then separate to form a new organism.

Organisms that reproduce in this way are yeasts, freshwater hydras, and sea anemones.

  • Fragmentation

Fragmentation consists of the separation of parts of the body, each one originating a new individual by regeneration.

Fragmentation occurs in starfish, algae, and plants.

  • Parthenogenesis

It is a kind of asexual reproduction that produces individuals excluded from the development of female gametes. For example, rose aphids, bees, and wasps.

  • Sporulation

It is also a kind of asexual reproduction that consists of the formation of reproductive cells or spores, from which a new individual can originate.

It takes place in molds.

Similarities B/w Asexual And Sexual Reproduction

  • Mode of reproduction that allows for genetic material to be passed on results in offspring.
  • Both allow for the continuation of a species
  • Asexual And Sexual Reproduction has a mitosis phase.
  • Offspring have the same number of chromosomes as the parent cells
