Classification of plants

1. Plants are divided into two main groups :
  • Flowering plants ( plants that produce flowers )
  • Non-flowering plants ( plants that do not have produce flowers ) 
2. Flowering plants are divided again into monocotyledons and dicotyledons
3. The table compares the dicotyledons and the monocotyledons


DICOTYLEDON
MONOCOTYLEDON
·         The seeds have only one cotyledon
·         The seeds have two cotyledons
·         They have parallel-veined leaves
·         They have net-veined leaves
·         They have a fibrous root system
·         They have a tap root system
·         They have non-woody stem
·         They have woody stem
·         Examples: wild grass,orchid plant, maize, sugar cane, palm tree and paddy
·         Examples: rose tree, bougainvillea, angsana tree, balsam plant and guava tree

EXAMPLES OF DICOTYLEDON :

MAIZE
PADDY

EXAMPLES OF MONOCOTYLEDON

BOUGAINVILLEA

ROSE


4. The non-flowering plants do not produce flowets. They produce spores in order to reproduce
5. Non-flowering plants are divided into three main groups :
  • mosses
  • ferns
  • conifers

CLASS
CHARACTERISTICS
a.       Mosses

·         Have chlorophyll
·         Grow in damp areas
·         Reproduction by spores
b.      Ferns
·         Have leaves, stems and roots
·         Have chlorophyll
·         Spores are formed at the back of the leaves
·         Grow in damp and shady areas
c.       Conifers
·         Have roots, stems and needle-like leaves
·         Have chlorophyll
·         They produce cones. They reproduce by seeds produced in the cones.
