Plant Diversity I. Plant Kingdom is Monophyletic: one common ancestor. Primary Products: main metabolic pathways Amino acid synthesis Production of cellulose Products needed for growth and development. Secondary Products: products for survival but not central metabolic needs Protection
Gametangia: organ of sterile cells protecting gametes
egg is fertilized in female gametangia
Division = Phylum
Charophytes: green algae closely related to plants
Charophytes : modern ones do not have alterations of generations. Most release gametes in water for fertilization to take place.
