Terrestrial Plant Anatomy Plants moved from water to land but there were challenges along the way… Challenge Getting water and minerals into the plant Adaptation Roots Fibrous root Taproot Major Functions of Absorption Transport of materials Storage of materials Anchorage Terrestrial Plant Adaptations Challenge Adaptation Getting water and minerals into the plant Roots Moving water and food within the plant Vascular tissue Vascular tissue Found in roots, stems and leaves of vascular plants - Cohesion – Water “sticks” to water + + - Adhesion – Water “sticks” to other molecules + + + Transpiration – Water loss from a plant leaf Vascular tissue Bundles are found in roots, stems and leaves of vascular plants 2 main types of vascular plants • Gymnosperms – cone bearing plants • Pine trees and fir trees • Angiosperms – flowering plants • Any tree, bush or plant that produces a flower Terrestrial Plant Adaptations Challenge Adaptation Getting water and minerals into the plant Roots Moving water and food within the plant Vascular tissue Plant body support Vascular tissue MERISTEMS – Regions of cell division @ tips of plant PRIMARY GROWTH growth in length of plant SECONDARY GROWTH Growth in thickness of plant Major Functions of Support Transport Storage Terrestrial Plant Adaptations Challenge Getting sunlight for photosynthesis Adaptation Leaves Terrestrial Plant Adaptations Challenge Adaptation Getting sunlight for photosynthesis Leaves Getting gas for photosynthesis and cellular respiration Stomata Terrestrial Plant Adaptations Challenge Adaptation Getting sunlight for photosynthesis Leaves Getting gas for photosynthesis and cellular respiration Stomata Preventing evaporation from plant surface Cuticle • Thin & Flat (SA/vol ratio) – Take in sunlight & CO2 • Cuticle – waxy layer – Prevent H2O loss • STOMATA – pore. H2O & O2 exit. – GUARD CELLS open & close • Transpiration – Loss of H2O by plant – > 90% of H2O is lost – Through stomata Terrestrial Plant Adaptations Challenge Adaptation Coordinating growth patterns and environmental response Hormones Getting sperm to egg without water Pollen Terrestrial Plant Adaptations Challenge Adaptation Coordinating growth patterns and environmental response Hormones Getting sperm to egg without water Pollen Dispersing new individuals to suitable locations Airborne spores then seeds Female Parts Carpel Stigma Style Ovary Male Parts Stamen Filament Anther
