Sexual reproduction: A process where two parents participate in producing their offspring. Let us study about sexual reproduction in this chapter. We will talk about asexual reproduction in another chapter. Sexual Reproduction. Sexual reproduction is a natural way of reproduction in humans, animals and the majority of plants also choose to reproduce sexually.
1. Give at least 5 organisms that produce sexually
Answer:
1. INSECTS
Insect species account for more than two-thirds of all animal species on the planet.
The majority of bug species reproduce sexually, however others are parthenogenetic.
Many insect species exhibit sexual dimorphism, while others have almost identical sexes.
They are usually divided into two sexes, with men producing spermatozoa and females producing eggs.
Before internal fertilization, the ova mature into eggs with a covering known as the chorion.
2. MAMMALS
Monotremes, placentals, and marsupials are the three types of mammals that exist today, all of which have internal fertilization.
Offspring of placental mammals are born as juveniles, which are full animals with all of their sex organs but are not capable of reproducing.
The sex organs mature to maturity after several months or years, depending on the species, and the animal becomes sexually mature.
3.FISH
Internal fertilization is used by some fish species, which then distribute the developing eggs or give birth to live offspring.
The guppy and mollies, or Poecilia, are two fish that have live-bearing offspring.sexually
Fish that give birth to live young can be ovoviviparous, in which the eggs are fertilized within the female and the eggs simply hatch within the female's body, or in which the male carries the developing young in a pouch and gives birth to live young, as in seahorses.
4. PLANTS
Animals have a single diploid multicellular phase in which haploid gametes are produced immediately during meiosis.sexually
Male gametes are referred to as sperm, whereas female gametes are referred to as eggs or ova.
In mammals, fertilization of the ovum by sperm results in the development of a diploid zygote, which grows into a diploid adult through repeated mitotic divisions.sexually
Plants have two multicellular life-cycle phases, which cause generations to alternate.
5.FERNS
Ferns produce rhizomes, roots, and leaves in huge diploid sporophytes.
Fertile leaves produce sporangia, which are haploid spore-bearing structures.
The spores are released and germinate, resulting in little, thin gametophytes with a heart shape and a green tint.
On the same or other plants, the gametophyte prothalli produces motile sperm in the antheridia and egg cells in archegonia.
