Title: Monocots . Vs . Dicots
1Monocots .Vs.Dicots
2Classification 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)
3- 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.
4Flowers
Monocots Dicots
3's or multiples of 6, rarely more than six 4, or 5, or multiples up to 10
5Embryo 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.
6Leaves
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.

Washingtonia Clivia Canna
7Vascular Tissue - Stem
Monocots Dicots
Scattered vascular bundles throughout the stem. Vascular bundles only on the perimeter of the stem.
8Root Pattern
Monocots Dicots
The roots are usually short and stringy. The root is often a single long tap root with smaller roots growing from it.
9Fun 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.
10Monocot or Dicot?
11Monocot 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.
