3. Life forms we can’t live without
Plants are one of two major Kingdoms of life forms. There are about
300,000 plant species on Earth. Plants are the only life forms that can produce
their own food using energy from sunlight. Plants produce almost all of the
oxygen in the air that humans and other animals breathe. Plants are also an
important source of food, building materials, and other resources that make
life possible for Earth’s animals.

4. Plants make life possible
• One of the most important things plants do is
create oxygen. This makes life on Earth
possible for animals. Large areas of plants
such as forests and grasslands are needed for
creating oxygen. Scientists and
conservationists worry that if large areas of
uncut forest are not protected, the whole
planet’s survival system could be harmed.

5. Food for Life
In addition to making food for themselves, plants
make food for animals. Animals eat many different plant
parts. For example, cows, horses, and antelope eat the
leaves of grass. Primates, such as monkeys, eat fruits and
leaves. People eat almost all parts of a plant including
underground roots and tubers (potatoes, carrots, and
radishes). We also eat leaves (lettuce, spinach), fruits
(oranges, apples, bananas), and seeds (rice, wheat, and
corn). Even the bark can be good! The cinnamon on a
breakfast roll comes from the bark of a cinnamon tree.
However, not all plants are good to eat. Some plants are
poisonous.

6. Plants and People
People are able to live all over the Earth because
plants make seeds that can be stored and carried to
other places. This has helped various species of
plant spread to many parts of the world. Think of
wheat, rice, corn, and beans. These plants are
grown all over the world. Without these important
foods, people’s lives would be very different. The
seeds of these plants are good to eat, full of
nutrients, and can be made into many different
foods.

7. The Source of Many Things
For centuries, plants have been one of the most useful natural
resources in the world. Even today, plants are one of the most
important materials people use for building houses, making clothes,
cooking, and heating. If you take a moment to think about all the
things that you use each day, you’ll find that plants are the source of
many of them. Here are some examples:
• Breakfast cereal (rice, corn, wheat, soy)
• The cardboard box the cereal came in (wood fiber from trees)
• The chair and table you sat at for breakfast (wood from trees)
• The books and paper you use at school (wood fibre from trees)
• The air you are breathing now (oxygen from plants)
• The clothes you are wearing (cotton, linen, and hemp from plants)

8. Four Groups
The plant kingdom consists of a wide range of
species. New plant species are being discovered
every day. All of them fits properly into four
plant groups.

9. Mosses & Liverworts
Mosses and liverworts are green plants that
are usually small. Their leaves are often just one
cell thick. Neither mosses nor liverworts have
any woody tissue, so they never grow very large.
There are about 14,000 species.

10. Ferns
Ferns are a very ancient family of plants.
Early fern fossils show that ferns are older than
land animals and far older than the dinosaurs.
They were thriving on Earth for 200 million years
before flowering plants evolved. Ferns live in
sheltered areas under the forest canopy, along
creeks and streams, and in other wet places.
They cannot grow well in dry areas. There are
about 12,000 species.

11. Cone Plants
Most cone plants, or conifers, are trees. They
represent some of the oldest and largest living
species on Earth. Conifers are often called
evergreen trees, because their leaves (thin
needles) usually remain on the trees all year.
They have no flowers or fruits. Instead, seeds
appear on cones and are scattered by the wind
or by animals. There are about 650 species.

12. Shoots, Roots, and Other Important
Plant Parts
• The basic plant structure includes two organ
(a part of the body that does a particular job)
systems: the shoot system and the root
system. The shoot system consists of the parts
of the plant that are above ground such as
leaves, buds, and stems. In flowering plants,
flowers and fruits are also part of the shoot
system. The root system is made up of those
parts of the plant below ground, such as the
roots, tubers, or rhizomes.

13. Flowering Plants
Flowering plants include many of the most
familiar plants. The distinctive feature of this plant
group is the flower, a cluster of specialized leaves
that help in reproduction. Not all flowers are as
bright and obvious as the sunflower blossoms in the
picture. Oaks, ivy, and grasses also produce flowers.
Their flowers are not as showy, so people don’t
always notice them. All flowering plants produce
seeds from which new plants grow. There are about
270,000 species.

14. Amazing Plants
Plants are the largest and oldest organisms
on Earth. The tallest plant is a coast redwood
tree in California in the United States. It stands
112 m tall. The oldest organism on Earth is
thought to be the creosote bush. This plant lives
in California’s Mojave Desert. One of these small
circular bushes was found to be nearly 12,000
years old!

15. Plant Reproduction – Flower Structure
anther
stamen
filament
petal
sepal
peduncle
Petal - Plays an important part in pollination
Sepal - Protects the other floral parts against dying out and fungal attack. There are
the same number as there are petals, and they are usually in green colour.
Receptacle - The swollen tip of the flower stalk. It is base on which the other parts of 15
the ilower stand.

16. Carpel – The female part of the flower
Stigma =
Surface on which pollen grain containing male
gametes, may be deposited.
Style =
Stalk that holds stigma in prominent position and
down which pollen tube may grow
Ovary =
Contains the ovule, which encloses the female
gametes. Ovary wall may become part of the fruit.
16

17. Stamen – The male part of the flower
Anther =
Produces pollen grain, containing male gametes,
within the sacs.
Filament =
Stalk that holds anther in position to release
pollen.

26. They look like easy questions, right? What
mark did you get out of 4 hope not less than 2
because then it means you havent understood
anything which means you have to read in
between lines and go through the ppt AGAIN!
