4. Non vascular plants
Do not have extensive transport system of vascular tissue
that transport water and nutrients throughout the plant
body.
Non vascular plant are informally named as Bryophytes.
Ex:- Marchantia sp, Anthoceros sp, Pogonatum sp
5. Vascular plants
Vascular plants have complex vascular tissue
system.
Vascular plants cover about 93% of existing
plant species.
They can be further divided into two groups.
1. Seedless vascular plants
2. Seed plants
6. Seedless vascular plants lack seeds and
disperse by means of spores.
They are categorized into two groups.
1. Phylum Lycophytes
2. Phylum Pterophytes
Phylum Lycophytes
Ex:- 1. club mosses - Lycopodium sp
2. spike mosses – Selaginella sp
Phylum Pterophyta
Ex:- Nephrolepis
8. Seed plants
Vascular plants consist of seeds are
called “seed plants”.
They represent the vast majority of living
plant species.
Seed plants can be divided into two
groups.
1. Gymnosperms
2. Angiosperms
9. Gymnosperms
Gymnosperms are “naked seed” plants as
their seeds are not enclosed in chambers.
Ex:-
Getum sp, Cycas sp, Pinus sp
10. Angiosperms
Angiosperms are “seed plant” group
accommodating all flowering plants.
Only Angiosperms originate within flowers
and mature into fruits.
Diversity of Angiosperms.
1. Monocotyledons
2. Dicotyledons
11. Monocotyledons Dicotyledons
The embryos have one cotyledon Embryos have two cotyledons
Fibrous root system Tap root system
Parallel veins in leaves Reticulate veins in leaves
Vascular bundles in the stem do not
have cambia and are scattered
Vascular bundles in the stem have
cambia and arranged in a ring
Features of Monocotyledons and
Dicotyledons
e.g. grasses, coconut, rice e.g. Rose, cucurbits, mango tree
