Transcript Plant Morphology

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
