Leaf Structure & Function Leaves are the primary photosynthetic organs. Petiole Axillary bud Leaflet Compound leaf Petiole Axillary bud Simple leaf Leaf structures include: one or more blades a stalk called a petiole that connects the leaf to a stem simple leaves have 1 blade compound leaves have multiple blades called leaflets veins that have a branched (dicots) or parallel (monocots) arrangement

Storage leaves Stem Evolutionary Adaptations of Leaves Leaves can be modified for a variety of functions: tendrils which cling to larger support structures spines to repel herbivores bulbs that store nutrients reproductive leaves that detach and give rise to a new plant (asexual) Spines Tendrils Reproductive leaves

3 Basic Plant Tissue Types Dermal tissue outer, protective covering of the plant Vascular tissue transports water, nutrients & gives structural support Ground tissue everything else! Dermal tissue Ground tissue Vascular tissue each of these tissues forms a continuous tissue system throughout the plant There is also a type of undifferentiated tissue called meristem which we will address later in this chapter.

More on Dermal Tissue… In nonwoody plants and structures (e.g., leaves) the dermal tissue is epidermis. epidermis is frequently covered with a waxy cuticle to minimize water loss some plants also have trichomes in epidermal tissue which provide protection from water loss, intense light and insects In woody plants the epidermis develops into a protective laver called periderm (part of the bark). Trichomes 300 μ m
