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

EXAMPLES OF GYMNOSPERMS

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

GROWING SEASONS

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.
