BIOL 210 Lecture Notes - Lecture 5: Meristem, Secondary Growth, Morphogenesis
Document Summary
Lecture #5 learning objectives: organization of the plant body. Explain (in brief) how the three processes involved in plant development (growth, morphogenesis and differentiation) change a meristematic cell into a specialized cell type of a tissue system. List features of a meristematic cell: actively dividing, usually situated at growing apex of plant parts (root/shoot tips, undifferentiated, primary cell wall only, thin, contain dense, granular cytoplasm, no intercellular space. Identify the apical meristems of the shoot system of your bean seedling. Explain the origins of the primary meristems and what they become in the primary organs of a plant. Explain the origin of the different tissue systems in primary growth: the apical meristem (found at the tips of roots/shoots) gives rise to the three primary meristems. The 3 primary meristems & their primary tissues/tissue system: ground meristem parenchyma, collenchyma, sclerenchyma (ground tissue system, protoderm epidermis (dermal tissue system, procambium primary xylem and primary phloem (vascular tissue system)
