CLASSIFICATION OF PLANTS INTO GROUPS
Plants can be classified into several groups. Plants can be grouped according to the structure of their
roots, stem, leaves, flower & seeds. Plants are classified in two major groups : non-vascular &
vascular plants.
• Lacks vascular tissues.• Does not have vascular
bundles for transporting food &water.
• They are called bryophytes.
NON-VASCULARPLANT
S
• Have vascular tissues.• Does have vascular bundles
for conducting food &water.• They are called
tracheophytes.
VASCULAR PLANTS
DESCRIPTION OF NON-VASCULAR & VASCULAR PLANTS
Non-vascular plants have 3 kinds. They are mosses, liverworts,&
hornworts.
mosses liverworts hornworts
Mosses are bryophytes that grow alone on
the ground. They are erect w/
short leafy stems & are anchored
to the ground by rhizoids.
Liverworts are so called because
their thallus looks like the liver’s lobes.
Unlike mosses, liverworts lie
horizontally on the ground.
Hornworts have a simple &
undifferentiated thallus & a
complex spore-bearing
structure.
DESCRIPTION OF MOSSES, LIVERWORTS & HORNWORTS
Vascular plants have 2 kinds. They are spore-bearing & seed-bearing plants.
spore-bearing plants seed-bearing plants
DESCRIPTION OF SEED-BEARING & SPORE-BEARING
• It constitute the other group of tracheophytes. About 95% of tracheophytes are seed-bearing.
Seed-bearing plants
• Their reproductive structures are called spores located in specialized structures called sporangia.
Spore-bearing plants
Seed-bearing plants are divided into two distinct groups of tracheophytes, the gymnosperms & the angiosperms.
SEED-BEARING
GYNOSPERMS
ANGIOSPERMS
• They produce naked seeds.• Their seeds are not enclosed in a
ovary.• Their seeds are enclosed in woody
structures called cones or strobili.• They are called conifers because
they produce cones.• In most gymnosperm, there is a
dominant main stem w/ conspicuously smaller branches.
• Their leaves are covered with thick layer of cuticle.
GYMNOSPERMS
DESCRIPTION OF GYMNOSPERMS
EXAMPLES OF GYMNOSPERMS
PINE TREE
HEMLOCK
SPRUCES
FIRS
ANGIOSPERMS
• Angiosperm are the flowering plants.• They produce seeds that are
enclosed in a ovary.• Fruit trees, bushes & vegetables
belong to this group.

ANGIOSPERM
DICOT MONOCOT
Angiosperms are divided into two subclasses – the dicotyledons &
monocotyledons.
Bases of Comparison Monocot Dicot 1. Arrangement of veins in the leaves
Parallel Netted
2. No. of seed leaf in the seeds 1 23. Presence of cambium tissue Absent Present4. Stem growth No secondary growth With secondary
growth5. Flower parts In 2’s or 3’s or
multiples of these numbers
In 4’s or 5’s or multiples of these numbers
6. Root system Fibrous Taproot7. Examples Coconut, grass, rice,
corn, orchid, banana and bamboo
Gumamela, guava, rose, santan, ipil-ipil, San Francisco and munggo
The table summarizes the difference between monocot & dicot.

THE OTHER WAY OF GROUPING SEED PLANTS IS ACCORDING TO THE LENGTH OF THEIR

PLANTS
PERENNIALS
ANNUALSThese are plants that grow and produce flowers, fruits
and seeds in one season and then die.
Most vegetable crops are annuals
DESCRIPTION OF ANNUALS
EXAMPLES OF ANNUALS
BEANS
PEAS
TOMATOES
BIENNIALSThese are plants that take two years to complete their cycle. The plants grow and develop
in a year’s time.
For its 2nd year, they produce flowers, fruits and
seeds and afterwards die.
DESCRIPTION OF BIENNIALS
EXAMPLES OF BIENNIALS
BEETS
TURNIPS
CARROTS
PERENNIALSThese plants lived for more
than 2 years. Their life cycle – growth of flower, fruit and
seed bearing activities continuously goes on.
Most of trees and many grasses belong to this group.
