Key Topics to Revise
1
The Root System
- Root is the descending, underground part of plant axis - positively geotropic and negatively phototropic
- Characteristics: Non-green, lacks nodes/internodes/leaves, protected by root cap, bears unicellular root hairs
- Four regions: Root cap (protection), Meristematic zone (cell division), Elongation zone (cell growth), Maturation zone (differentiation and absorption)
2
The Stem System
- Stem develops from plumule - ascending axis, negatively geotropic and positively phototropic
- Characteristics: Bears nodes and internodes, terminal bud for growth, lateral organs are exogenous
- Weak stems: Twiners (coil around support), Climbers (use tendrils/roots/hooks), Trailers (creep without roots), Creepers (creep with adventitious roots)
3
The Leaf System
- Leaf parts: Leaf base (sometimes with stipules), Petiole (leaf stalk), Lamina (expanded blade)
- Leaf shapes: Linear, lanceolate, ovate, cordate, sagittate, etc. - know shapes with examples
- Leaf types: Simple (single undivided lamina) vs Compound (lamina divided into leaflets)
4
Inflorescence
- Inflorescence is arrangement of flowers on specialized branch system
- Types: Racemose (indefinite/acropetal growth), Cymose (definite/basipetal growth), Mixed, Special types
- Racemose types: Raceme (pedicellate flowers on elongated axis), Spike (sessile flowers), Corymb (flat-topped), Umbel (umbrella-like), Capitulum (head)
