Aerial roots of orchids
Roots that spread across the bark of living trees
Contractile roots
Contract to pull the shoot or bulb downward
Caused by a change in shape to the cortex cells
Mycorrhizae
Relationship where fungi invades a plants cells
Origin and development of lateral roots
Initiated by cell division in pericycle
Breaks endodermis to emerge
Begins deep within the root
Forms in mature regions of the root
Internal structure of roots
Root cap
Thick layer of cells
Protects the apical meristem
Constantly being renewed
Apical meristem
Creates all primary root cells
Zone of elongation
Area where cells begin to expand exponentially
Where cells begin to differentiate into a visible pattern
Root hair zone
Maturation zone
Where root hairs begin growing outward
Anything entering the cell is carefully filtered in this area
External structure of roots
Lateral roots
The roots that shoot out from the taproot
Radicle
Embryonic root
Present in the seed
Fibrous roots
Mass of similarly sized roots
Occurs because the radicle dies during or right after germination
Known as adventitious roots
Taproots
Usually larger in diameter than the lateral roots
Central part of any root system it is part of
