BIOL 1020 Lecture Notes - Vegetative Reproduction, Asexual Reproduction, Parenchyma
Document Summary
Plant body parts: stems: from the roots to the apical bud, raise leaves into sunlight, vegetative shoots, reproductive shoot, may be photosynthetic, food storage, asexual reproduction (vegetative, examples: Stolon: above ground stem that extends horizontally (strawberry plant) Leaves: photosynthesis, basic anatomy: blade and petiole figure 35. 6. Doubly compound leaf: tendrils: grabbing onto other plants to help plants climb, spines: defense, storage leaves: store water, reproductive leaves: vegetative reproduction, bracts (often mistaken for petals, plant tissue systems, dermal tissues: usually always on the outside. Non-woody plants: epidermis: waxy cuticle: helps prevent water loss. Woody plants, protective tissues called periderm replace the epidermis in older regions of stems and roots: vascular tissues: transport water throughout the plant. Xylem (water) and phloem (sugar: ground tissue: neither dermal nor vascular composed of pith and cortex variety of functions support photosynthesis storage. Sclereids: core of an apple: short and irregular in shape, thick lignified secondary walls.
