Presentation Transcript

  1. Alternation of Generations A type of life cycle found in plants that alternates between 2 different versions of adult plants – the sporophyte and the gametophyte plant

  2. The Sporophyte plant produces spores, which after released, will germinate and each spore will grow into a new plant (the gametophyte) • The Gametophyte plant produces gametes, (eggs and sperm). After an egg and sperm unite (fertilization), the zygote will germinate and grow into a new plant (the sporophyte) • The lifecycle continues, with sporophyte plants reproducing gametophyte plants and visa versa – alternating between the twoplant types

  3. Sporophyte gametes spores gametophyte
