Kingdom Plantae Another of our kingdom survey Biology I / Mr. Fuentes
Kingdom Plantae Plants dominate the land and many bodies of water. They exhibit tremendous diversity. Some are less that 1 mm to other as big as 100 m.
Objectives • Name characteristics of plants • Summarize the classification of plants • Describe adaptations of plants to live on land
Analyze this picture: (in groups) What do you see? What can you make of this picture?
Analyze this picture: (in groups) What do you see? What can you make of this picture? Which organism do you think plants evolved from?
Which plants are thought to be the first ones to appear on land? In what order they appeared?
Characteristics • Plants do all share some characteristics: • All plants are Photosynthetic. • All Plants are Multicellular. • All Plants are Eukaryotic Organisms..
Adaptations of plants to live on land • From aquatic algae, aquatic plants to land plants. • Cuticle to prevent water loss. • Reproducing by spores and seeds. • Vascular tissue.
Objectives • Distinguish between vascular and non vascular plants • Explain the advantages of seeds for reproduction on land • Distinguish between dicots and monocots
Classification Non vascular Vascular Dispersal {spore (Single cell) vs. seed} Body an axis (stern) Large surface Many subdivision and classes Body structure Vascularization • Disperse by spores (seedless) • Not true roots, stems or leaves • Small • No vascular tissue • Grow in clumps or masses • Many capable of prolonged dehydration • Most lack cuticle (protective surface layer)
Advantages of seeds for reproduction on land • Greater chance of reproduction success • Protection of the embryo
Two main groups of seed plants Angiosperms Gymnosperms Seeds in fruit bodies Flowering plants • Naked seeds in cones
Seeds Plants Angiosperms Gymnosperms
Two groups of flowering plants Monocots Dicots Two cotyledons • One cotyledon
Flowering Plants Monocots Dicots
