Classification of Plants
 Plants are the fundamental building blocks of life on earth.
Plants are life forms belonging to the kingdom Plantae.
 The scientific study has revealed at least 500,000 species of
plants. The types of plants vary in size from microscopic algae,
to huge sequoia trees more than 8m (26 ft) tall.
 Plant Kingdom is mainly classified into two . This type of plant
classification is done according to how they reproduce.
 1) Spore bearing plants ( Algae, mosses, ferns and their relatives)
2) Seed bearing plants. (Conifers and flowering plants)
 The plant kingdom can also be classified on the basis of the
presence or absence of conductive (vascular) tissue.
 Ferns (pteridophytes), gymnosperms and angiosperms have
vascular tissue which transports the nutrients and water
through the plant.
 Mosses, liverworts, hornworts are non-vascular i.e. they do not
have conductive tissue to transport sugar, water and nutrients.
Flowers

3's or multiples of 4, or 5, or

Embryo in seed - Cotyledons
Monocots
Dicots
Have only one seed leaf
inside the seed coat. It is
often only a thin leaf,
because the endosperm to
feed the new plant is not
inside the seed leaf.
Two seed leaves inside the
seed coat. They are usually
rounded and fat, because
they contain the endosperm
to feed the embryo plant.
Inside is a tiny plant called an embryo. The outer parts of the
seeds are called cotyledons. They supply the food for the
young plant when it's growing.
Leaves
Monocots
Dicots
The leaves are often long and
narrow, with their veins in
straight lines up and down
the leaf. Sometimes, the
veins run from the center of
the leaf to the edge, parallel
to one another.
Leaves come in many
different shapes and sizes.
The veins go from the central
midrib to the edge of the
leaf, crossing and joining to
form a netted pattern all
over the leaf.

only on the
perimeter of the
stem.

The roots are usually The root is often a

Fun Facts
About 65,000 monocot species are known
worldwide
About 170,000 dicot species are known
worldwide
Nearly all our deciduous trees and common
flowering bushes and vines are dicots, but
nearly all grasses and grasslike things are
monocots.
Monocot or Dicot?
Monocot or Dicot?
 The leaves appear to have
parallel veins, so there's a vote
for "monocot."
 However, this flower seems to
have only two petals, and that
doesn't fit either monocot or
dicot.
 The main proof is that
actually there is a third petal,
a much reduced, translucent
one at the flower's bottom, so
there are also three petals.
 Therefore: Monocot.
