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!
