Sort the descriptions based on whether they are related to asexual reproduction or sexual reproduction
miss Akunina [59]

Answer:

Sexual Reproduction:

  1. Creates genetically unique offspring.
  2. Organism needs time to  reach adulthood and to reproduce.
  3. Requires the contribution of two parents.

Asexual Reproduction:

  1. Creates genetically identical offspring.
  2. Organism doesn't have to waste energy to find a mate.
  3. Requires the contribution of a single parent.

Explanation:

Sexual Reproduction:

  • Sexual reproduction involves the fusion of a male and female gamete. A gamete is a haploid cell that contains half of the chromosomes as in the parent cell. This process is called fertilization and it results in the formation of a zygote, a diploid cell that develops into an embryo and ultimately an individual.
  • Sexual reproduction involves two parents, each of which contributes one set of chromosomes (23) to the offspring.

Asexual Reproduction:

  • Asexual reproduction produces an exact copy of one single parent. Offspring produced through asexual reproduction do not possess genetic variation.
  • Asexual reproduction occurs through four processes:
  1. Binary fission
  2. Fragmentation
  3. Budding
  4. Parthenogenesis

nectar is very sweet juice which attracts insects.

when those insects suck the nectar the pollen grains sticks to the body of those insects and then when they fly and sit on the other flowers and then those pollen grains are then transferred to the stigma of that flower which then forms a zygote and then forms a new flower.

and this is how nectar helps to reproduce
