Don't know?
Terms in this set (136)
Radicle (primary root) emerges from seed; grows vertically (down)
, Secondary root forms root systems, anchors plant, and stores food
Taproot system large primary root and smaller secondary roots
Fibrous root system primary and secondary roots are similar in size
Primary growth produced by apical meristems, produces
herbaceous (non-woody) tissue; vertical growth
Secondary growth growth in girth, horizontal growth
Root cap protects the apical meristem as root pushes
through soil
Root apical meristem region of active cell division for elongation
Zone of elongation cells lengthen, pushing root tip forward
Zone of maturation differentiation; cells mature into xylem, phloem,
parenchyma, or epidermal cells (root hairs may
grow here).
Zone of division cells actively dividing
Epidermis outer protective tissue
Cortex ground tissue for storage and support
Endodermis regulates water and mineral entry into vascular
cylinder
Xylem water + minerals
