Plants come in
many shapes,
sizes and
colours.
TASK 1.
Take a look outside,
how many plants can
you see?
Different types of
plant grow in
different places all
around the world!
In this presentation, I
hope to show you
exactly what plants
are.
•Carpel - consists of the
stigma, style, and ovary.
•Stigma - the tip of the carpel
that is sticky in order to
collect pollen
•Style - the slender, neck-like
portion of the carpel that
leads to the ovary.
•Ovary - structure at the base
of the carpel that houses the
ovule or egg.
Here are the main organs of a
flowering plant, they are not in

was missing any on of these it

protects the budding flower.
•Petal - colourful and often scented part of
the flower that attracts insects
•Stamen - the part of the flower that
produces pollen. Consists of a filament and
an anther.
•Anther - sac located at the tip of the
filament that contains pollen.
•Filament - stalk that connects to and holds
up the anther.

WHAT DOES
Flowering mean:
flowering means a plant
will produce flowers
sometime in the year!
Non-flowering: nonflowering means that a
plant will never produce
flowers!
As you can see in the
pictures!
Monocotyledons make a seed with a seed
coat. Inside the seed there is plant embryo
with a primitive root and a supply of food for
the new plant. The food supply is called the
endosperm, and it is all in one piece. When
the little plant comes out, the root goes
down and a single spire goes up. The young
plant uses the food resources of the
endosperm to provide energy for growth.
The endosperm part (the inside of the corn
kernel in our example) is the single seed
leaf: the monocotyledon The parent plant
has stored food in this kernel so that the
young plant will have energy resources that
it can use to start building itself up as the
seed germinates
Dicotyledon seeds also contain an embryo plant.
The seed is protected by a seed coat. There are two seed
leaves inside the diocotyledon seed. The seed leaves
nourish the plant after it germinates.

Perennial plants are plants which will continue
growing year after year, rather than dying off after
a season or a year like annuals do. There are a
number of different kinds of perennial plants, with
gardeners using perennials as permanent fixtures
in their gardens. Gardening stores and nurseries
typically stock a range of perennial options, most
of which are suitable for the climate the store is
located in, and it is also possible to order specific
perennials.
