PLANT KINGDOM Non Flowering Plants – Algae Mosses (Bryophytes) Ferns (Pteridophytes) Conifers (Gymnosperms) B. Flowering plants– Angiosperms Angiosperms divided into following subgroups. Dicotyledon Monocotyledon

FERNS Plants have root, stem and leaves. The leaves of ferns called fronds. They do not produce flowers. Reproduce by mean of spores produced on the underside of fronds.

FERNS : Reproduction by spores Reproduce by mean of spores produced on the underside of fronds.

Flowering PLANTS (ANGIOSPERMS) Plants have root, stem and leaves. Reproduce by mean of flowers and seeds. Seeds are produced inside the ovary, in flower. Classified into two groups. A) Monocot B) Dicot

MONOCOT AND DICOT PLANTS How can we identify on the basis of external/internal features…?

ROOT DICOT : Have tap root system MONOCOT : Have fibrous root system

STEM Vascular bundles In dicot stem: Vascular bundles are arranged in a ring. In monocot stem: Vascular bundles are scattered.

LEAF In dicot :Leaves have reticulate venation. In Monocot :Leaves have parallel venation.

FLOWER Floral parts are four / five or multiple of four /five. Floral parts are three or multiple of three.

POLLEN GRAIN

SEED Monocot: One cotyledon Dicot: Two cotyledons
