Plant Structure Adaptations and Responses

Principle purpose of this lecture is to present on Plant Structure Adaptations and Responses. Here briefly present on Functions of Stems: Support system for plant body; Transport system carries water & nutrients and Holds leaves & branches upright. Here also focus on Functions of Leaves: Have systems to prevent water loss; Stomata open in day but close at night or when hot to conserve water and waxy cuticle on surface. Finally describe on Leaf Structures: Cuticle: waxy layer; covers upper surface; Veins: transports water, nutrients and food and Mesophyll: contains cells that perform photosynthesis.
