How can plants be classified?
Plants are classified in many different ways.
You can classify them into the following groups.
Class Subclass Superorder Order Family
Subfamily Tribe Subtribe Genus Species Variety Form And cultivar

What are the main parts of a flowering plant?
Most flowers have four main parts, they are: Sepals – sepals protect the bud of the flower
before it opens up Petals – petals attract insects to the plant Stamens – stamens make the pollen on the
flower Carpels – carpels grow into fruit which
contain seeds

What are monocotyledons and dicotyledons?
Monocotyledons and dicotyledons are two major groups of flowering plants.
Monocots seedlings generally have only one cotyledon (seed-leaf) whereas dicot seedlings have two.
Definition of monocotyledon – flowering plant with a single embryonic seed leaf.
What is the difference between monocotyledons and
dicotyledons?
Feature In monocots In dicots
Number of parts of each flower
in threes in fours or fives
Number of furrows or pores in pollen
one three
Number of cotyledons (leaves in the seed)
one two
Arrangement of vascular bundles in the
stem
scattered in concentric circles
Roots are adventitious develop from the radicle
Arrangement of major leaf veins
parallel reticulate

Some Facts About Non-Flowering Plants
There are about 4,500 different species of non-flowering plant in the world.
They can be found under water or on land. Around 30-40% of non-flowering plants are
endemic to the country.
Thanks for watching and learning!
