Transcript
Plant Morphology • Meristem Tissue- embryonic tissue located at the tips of roots and stem apices (herbaceous & woody plants) and cambium layers (woody plants). • Parenchyma - unspecialized cells occurring throughout the plant. • Sclerenchyma- hollow, non-living cells with thick walls; structural support Transport System Xylem Tissue- transports water and minerals from the roots to the leaves; Phloem Tissue- transports organic nutrients from the leaves to the roots Herbaceous and Woody Stems Herbaceous plants exhibit only primary growth while woody plants have secondary growth. Nonvascular Plants Bryophyta- the mosses Hepatophyta- liverworts Seedless Vascular Plants Lycopodophyta- club mosses Psilophyta- whisk ferns Equisetophyta- horsetails Pteridophyta- ferns Seed Vascular Plants • Gymnosperms • Angiosperms Coniferophyta- conifers Magnoliophyta- flowering plants • Class Magnoliopsida- dicots • Class Liliopsida- monocots Flower Anatomy Monocot one cotyledon Dicot two cotyledons parallel venation dedritic venation scattered vascular bundles flower parts in three vascular bundles forming a ring flower parts in four or five
