Plant Structure Adaptations and Responses

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.
