Tissue and Primary Growth of Stems
Internal Organization of Stems
Epidermis
outermost part of stem
proctective layer
Cortex
consist of thin walled parenchyma cell
transport of minerals to central cylinder through the root
lies below epidermis
Vascular Tissue
Xylem
conducts water & minerals from roots to leaves
Vascular bundle
phloem
transport minerals & sugar from leaves to different part of the plant
Basic Types of Cell & Tissue
Sclerenchyma Cell
dead cell with highly thick cell wall
provide strong, rigidity and flexibility mechanical support to the plant
Parenchyma Cell
Thin living cell wall
form basic ground tissue and store food
Collenchyma Cell
photosynthesis can occur if chlorophyll present
give mechanical support to plant
Thick living cell wall
Meristematic Tissue
Stem growth & differentiation
Apical Meristem
Sub-apical Meristem
