Sexual reproduction requires….
Fertilization, which is the union of 2 cells from 2 individual organisms.
Haploid cells
One set of chromosomes
Diploid cells
Two sets of chromosomes
of sets of chromosomes in a cell
Ploidy level
Somatic cell
Body cells or All cells of a multicellular organism except gametes or reproductive cells
of copies of each chromosomes in the nucleus
2
Homologous chromosomes
The two chromosomes inside the nucleus
Diploid organisms inherit one copy of each…
Homologous chromosome from each parent.
Spores
Haploid cell that can produce a haploid organism or fuse w/ another spore to form a diploid cell
Haploid cells are found….
Within structures that give rise to either gametes or spores
All animals and most plants produce
Eggs and sperm, or gametes
Some plants and all fungi produce…
Spores
