A report on Sexual reproduction
Type of reproduction that involves a complex life cycle in which a gamete with a single set of chromosomes (haploid) combines with another to produce a zygote that develops into an organism composed of cells with two sets of chromosomes (diploid).

The apothecium—a specialized structure important in sexual reproduction in the ascomycetes—is a cup-shaped fruit body that is often macroscopic and holds the hymenium, a layer of tissue containing the spore-bearing cells.
Meiosis
12 linksMeiosis (, since it is a reductional division) is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells.
Fertilisation
12 linksFusion of gametes to give rise to a new individual organism or offspring and initiate its development.
Fusion of gametes to give rise to a new individual organism or offspring and initiate its development.
The cycle of fertilisation and development of new individuals is called sexual reproduction.
Gamete
8 linksA gamete (, ultimately ) is a haploid cell that fuses with another haploid cell during fertilization in organisms that reproduce sexually.
Chromosome
8 linksLong DNA molecule with part or all of the genetic material of an organism.
Long DNA molecule with part or all of the genetic material of an organism.
Chromosomal recombination during meiosis and subsequent sexual reproduction play a significant role in genetic diversity.
Reproduction
7 linksBiological process by which new individual organisms – "offspring" – are produced from their "parent" or parents.

There are two forms of reproduction: asexual and sexual.
Ploidy
10 linksNumber of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes.
Number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes.
Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle.
Biological life cycle
6 linksSeries of changes in form that an organism undergoes, returning to the starting state.
Series of changes in form that an organism undergoes, returning to the starting state.
Transitions of form may involve growth, asexual reproduction, or sexual reproduction.
Egg cell
6 linksThe egg cell, or ovum (plural ova), is the female reproductive cell, or gamete, in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one).
Plant

Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae.
Plants are characterized by sexual reproduction and alternation of generations, although asexual reproduction is also common.
