Roots and Stems Flashcards
(18 cards)
Protects tissues from damage as roots grow
Root Cap
Establishes epidermis, cortex, pith, xylem and phloem
Zone of division
cells become several times original length
Zone of elongation
cells differentiate into various distinctive cell types
Zone of differentiation
absorb water and minerals
Root Hair
nutrient storage and transport
Pith
photosynthesis/ wound healing
Parenchyma
Transport of water and minerals
Metaxylem
Allows for elongation and growth
Protoxylem
Transports sugar and organic compounds
Phloem
assists, supports, and protects xylem and phloem
Pericycle
moves water ions and hormones in and out
Endodermis
transports and stores nutrients and support
Cortex
provides mechanical support and strength
Sclerenchyma
Barrier against environmental factors
Epidermis
with rapidly dividing cells; at stem apex
Apical Meristem
will develop into true leaves
Leaf primordia
will develop into axillary buds
Axillary buds primordia
