Root is the part of a plant which attaches it to the ground If the radicle grow continuously into roots that branch
and to support the plant, typically underground, conveying out into smaller roots. The root derived from the
water and nutrient to the rest of the plant via numerous radicula is called the tap root.
branches and fibers.
FIBROUS ROOT SYSTEM
CHARACTERISTIC OF ROOT
1. Geotropic and hydrotropic
2. Doesn’t have a node
3. The color isn’t green If the radicle in later development die or are followed by
4. It has a pointy shape some roughly equally large roots and all emerge from
5. Usually inside the ground the base of the stem and the shape like fibers.
6. The tip of root continuous to grow
MODIFICATION
FUNCTION OF ROOT
1. Strengthen the plant 1. Taproot modification
2. Absorbing water and soluble food stuffs in 2. Fibrous root modification
water from the ground 3. Adventitious root modification (root
3. Transport water and nutrient to the bodies of that arises from any point other
plant than the radicle or the root axis)
4. In some plant it has function to hoard food
3 D. Moniliform or Beaded
STRUCTURE OF ROOT roots
COLLUM : part of roots that connect to the base stem A. Tuberous root
APEX RADICIS : the youngest part of the roots
CORPUS RADICIS : the part that lies between collum 1 2
and apex radicis
Rose moss (Portulaca
RADIX LATERALIS : It doesn’t directly connect to the
3. Filiformis . Eg : Kratok A. Composed of tiny C. Big as arm grandiflora)
base stems but by the roots (root branches) Sweet potato (Ipomoea
E. Palmate tuberous roots
FIBRILLA RADICALIS : delicate root branches (Phaseolus lunatus L.) fibers batata)
PILUS RADICALIS : to expand the absorption field and Love-vine (Cassytha B. Fasciculated root
CALYPTRA : located at the root tips to protect root filiformis)
when it expands the absorption area
(Pandanus
(Oryza sativa L.) tectorius) Orchid (Orchis mascula)
B. Stiff, hard, and big F. Annulated roots
A. Taproot that has little or no branching : Menow weed (Ruellia)
1. Fusiformis . Eg : Beta vulgaris 2. Napiformis . Eg : B. Branched tap roots (ramosus) : as mine C. Nodulose root
Pachyrhizus erosus
Ipecac (Cephaelis
(Cocos nucifera L.) ipecacuanha)
Arrowroot (Maranta sp.)
