Solution

Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.


Diploid having two sets of chromosomes or double the haploid number of chromosomes in the germ cell, with one member of each chromosome pair derived from the ovum and one from the spermatazoon. The diploidnumber, 46 in humans, is the normal chromosome complement of an organism's somatic cells.

Oogamous having or involving a small motile male gamete and a large immobile female gamete.

Anisogamous is the form of sexual reproduction that involves the union or fusion of two gametes, which differ in size and/or form. The smaller gamete is considered to be male, whereas the larger gamete is regarded as female.

Aplanospore is a nonmotile asexual spore formed by rejuvenescence in certain algae and distinguished from an akinete by developing a new cell wall distinct from that of the parent cell .

A zoospore is a motile asexual spore that uses a flagellum for locomotion. Also called a swarm spore, these spores are created by some protists, bacteria and fungi to propagate themselves.

A conidiaspore sometimes termed an asexual chlamydospore or chlamydoconidium, is an asexual, non-motile spore of a fungus.

Sporangiospores are spores that are produced in a sporangium (plural: sporangia). A sporangium in fungi (but not mosses and some other organisms) is simply a cell containing spores.

An oospore is a thick-walled sexual spore that develops from a fertilized oosphere in some algae, fungi, and Oomycetes. They are believed to have evolved either through the fusion of two species or the chemically-induced stimulation of mycelia, leading to oospore formation.

An ascospore is a spore contained in an ascus or that was produced inside an ascus. This kind of spore is specific to fungi classified as ascomycetes. Ascospores are formed in ascus under optimal conditions. . Typically, a single ascus will contain eight ascospores.

A basidiospore is a reproductive spore produced by Basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidia

Gamete is a mature haploid male or female germ cell which is able to unite with another of the opposite sex in sexual reproduction to form a zygote.

A gametophyte is one of the two alternating phases in the life cycle of plants and algae. It is a haploid multicellular organism that develops from a haploid spore that has one set of chromosomes. The gametophyte is the sexual phase in the life cycle of plants and algae.

Meiosis is a specialized type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell that gave rise to them.


mitosis is a part of the cell cycle when replicated chromosomes are separated into two new nuclei.
