Alternation Of Generations Life Cycle at Life

Alternation Of Generations Life Cycle. The life cycle of a plant is called the alternation of generations. The two phases, or generations, are often morphologically, and sometimes chromosomally, distinct.

A fern's spores don't grow. The two generations or life cycles that occur are called the sporophyte generation and the gametophyte generation. This is called alternation of generations.

This is called alternation of generations. When haploid (n) or gametophytic generation and diploid (2n) or sporophytic generation repeat alternately in the life cycle of any organism, it is called alternation of generation. Summary alternation of generations all plants undergo a life cycle that takes them through both haploid and diploid generations. • diploid (2n) individuals called sporophytes and haploid (n) individuals called gametophytes generate each other in the life cycle • male and female gametophytes produce gametes by mitosis • fertilization results in a diploid zygote • the zygotes undergoes mitosis and develops into the diploid sporophyte • the sporophyte produces haploid spores by meiosis • a.
