1 Plant Life Cycles Plant life cycles alternate between two cycles: Producing spores and producing gametes A two phase life cycle is called alternation of generations Diploid phase Haploid phase Alternates between PHASE fertilization the two PHASE meiosis The spore producing plant is the mature sporophyte phase h is diploid id Begins with fertilized Spores produced through meiosis The gamete producing plant is the mature gametophyte phase is haploid Begins with ihspore Gametes produced through mitosis fertilization PHASE PHASE meiosis Life cycle phases look different among various plant groups Nonvascular plants have a dominant gametophyte phase Moss gametophytes look like green carpet Moss sporophytes shoot up as stalk like like structures sporophyte (2n) gametophyte (1n) capsule spores (1n) 1) Moss gametophytes grow near the ground (haploid stage) 2) Through water, sperm from the male gametophyte will swim to the female gametophyte to create a diploid 3) Diploid sporophyte will grow from 4) will create and release haploid spores 5) Haploid spores land and grow into new gametophytes 6) The process repeats male male female female female male female male ground

8 Flowering plants can be pollinated by wind oranimals Wind pollinated flowers have small flowers and large amounts of pollen Animal pollinated flowers have larger flowers and less pollen many flowering plants pollinated by animal pollinators pollination occurs as animal feeds from flower to flower animal pollination more efficient than wind pollination Fertilization takes place within the flower Male gametophytes, or pollen grains, are produced in the anthers male spores produced din anthers by meiosis each spore divides by mitosis to form two haploid cells two cells form a Pollen grain single pollen grain Stamen Filament Anther One female gametophyte can form in each ovule of a flower s ovary 1 Pollen stick to animal or released into wind Many cells can be made in the ovule One cell becomes the One cell becomes 2 polar nuclei The rest die Polar nuclei (2n) 2 Animal finds a new flower to feed on and pollen grains land on the stigma (pollination) 3 Pollen tube grows and 2 nuclei transfer into the ovule Let s zoom in
