Alternation of generations is the type of life cycle that occurs in those plants and algae in the Archaeplastida and the Heterokontophyta that have distinct sexual haploid and asexual diploid stages. In these groups, a multicellular gametophyte, which is haploid with n chromosomes, alternates with a multicellular sporophyte, which is diploid with 2n chromosomes, made up of n pairs. A mature sporophyte produces spores by meiosis, a process which reduces the number of chromosomes to half, from 2n
How to Format an APA Works Cited List. Label the page References centered at the top. Double space the entire list. Every line after the first line of a citation should be indented one-half inch from the left margin (also known as hanging indentations). Alphabetize your entire bibliography list. Add the annotation on the next line below the citation. Further indent the annotation two more spaces (for a total of four spaces).
