SOME BASIC DEFINITIONS
Ploidy - the number of copies of genetic information that an organism has in its cells.
Haploid* - ONE copy of genetic information. Often represented in diagrams simply as "n"
Diploid* - TWO copies of genetic information (one from each parent). Often represented simply as "2n"
Gamete - single cell haploid
Gametophyte - multi-cellular haploid (in PLANTS only)
Sporophyte - multi-cellular diploid (in PLANTS only)
Fertilization - when two haploid gametes join to form a diploid zygote
Mitosis - cell division (can be either diploid or haploid cells)
Meiosis - special kind of cell division where a regular diploid cell forms 4 haploid gamete cells

Here we compare and contrast the life cycles of plants and animals. First, several key definitions will be provided followed by a general description of each life cycle. Finally, several points about the similarities and differences are made.
