Why must the life cycle of sexually reproducing species alternate between haploid and diploid stages?

Meiosis maintains the normal diploid number by halving the number to make the gametes and then allowing the diploid number to be restored through fertilization.
For example in humans:
Germ cells undergo meiosis --> Sex reproduction
2n germ cells --> 1n gametes --> 2n fertilization

What is the difference between a haploid cell and diploid cell?
A diploid cell differs from haploid is that the diploid cell has homologous chromosomes as when the haploid cell doesn't have homologous chromosomes.
The life cycle of nonvascular plants includes an alternation of generations between a?
diploid sporophyte and a haploid gametophyte
The table below shows the number of chromosome pairs for various organisms. Which organism can produce the highest number of genetically different gametes?
Carp, Giraffe
Is a capsule a haploid or diploid?
Diploid..
Is ovaries haploid or diploid?
diploid
How do gametes return to the diploid number of chromosomes for sexually reproducing organisms?
They merge.
How do sexually reproducing organisms produce gametes from diploid progenitors?
Through Meiosis
When and in what cells does meosis happen?
Meiosis occurs when diploid cells produce haploid daughter cells and takes place in sexually reproducing organs.
What is meitoic?
The process of cell division in sexually reproducing organisms that reduces the number of chromosomes in reproductive cells from diploid to haploid, leading to the production of gametes in animals and spores in plants.
What are the 5 kingdoms characteristics?
Plants are 1) Eukaryotic, 2) Photosynthetic, 3) Multicellular, 4) Sexually reproducing, and 5) their Life History involves an alternation of a haploid phase (Gametophyte) with a diploid phase (Sporophyte)
Is a mushroom diploid or haploid?
The thallus is haploid. It depends on the three basic life cycle of sexually reproducing fungi, in haplobiontic A life cycle, the thallus is haploid, in haplobiontic B life cycle the thallus is diploid and in diplobiontic life cycle, it has two thallus, a sporophytic thallus which is diploid and a gametophytic thallus which is haploid.
The term gamete is used to describe?
A haploid cell that when combining with another in a sexually reproducing system makes a diploid organism. Sperm and eggs are human gametes that combine, each bringing half the genetic material needed for a complete set.
Are human body gamete cells haploid or diploid?
From a text book.. diploid cell- In an organism that reproduses sexually, a cell containing two homologous sets of chromosomes, one set of inherited from each parent; a 2n cell haploid cell- In the life cycle of an organism that reproduces sexually, a cell containing a single set of chromosomes; an n cell ...diploid?
An organism that reproduces sexually has a diploid number of 30. How many chromosome will a gamete of this organism have?
15- apex
What has two like genes or alleles?
Diploid organisms, like humans, have two alternate like alleles for every gene.
What is haploid or n cell?
A haploid is a egg born from the mother.The newborn comes out from the mother.It turns into a baby and a toddler and then it turns into a preschooler.A cell is like something in your body and it rumbles.
What is the difference between haploid diploid and zygote?
There are two types of cells in the body - haploid cells and diploid cells. The difference between haploid and diploid cells is related to the number of chromosomes that the cell contains.
