The plant kingdom is made up of organisms with many cells. Cells are organised according to tissues
Plants get the nutrients, but they don’t eat other organisms.
They have these common characteristics:
 Plants are multicellular organisms. They are made up of many cells which form tissues.
 Plants have got eukaryotic cells.
 The cell has got a nucleus and organelles surrounded by membranes.
 It is surrounded by a cell-wall made up of cellulose.
 It has got chloroplasts filled with chlorophyll. This green pigment is responsible for
photosynthesis
 Plants have autotrophic nutrition. They get organic matter through photosynthesis. This process
requires light, which is captured by chlorophyll, a green substance found in the plant’s leaves
 All of plants have got roots, stems and leaves. These vary according to the species
 Plants cannot move. They live anchored to the ground by roots. But they can make some
movements ( for example, they can open and close their flowers and leaves ).

They are the smallest and simplest plants. They are non-vascular plants (with no
conductor vessels which transport water) so they depend on the water to survive, and have
not got any vegetative organs (no roots, no stem, and no leaves). They live in damp places;
on the ground, on the surface of rocks, and on tree trunks.

They are medium-sized vascular plants (with conductor vessels which transport water and
nutrients). They have got vegetative organs (root, stem, and leaves) but they have not got
flowers or fruits. They have large leaves, called fronds, which are separated into small
leaflets. They also live in damp places.

The pine tree, the cypress or the sequoia belong to this group. They are mainly big trees and form big
forests.
 Gymnosperms are mainly evergreen-leaves trees. The leaves are hard and strong and usually
have needle-shape, like the pine tree, or scales like the cypress.
 Gymnosperms have got small, insignificant flowers. The flowers group together into
inflorescences or cones. These cones are male and female.

The olive tree, the oak tree, and the wheat belong to this

and trees. They live in all kind of climates.
 Many angiosperms are deciduous. They lose all
their leaves in winter so they can live in the cold
weather. The leaves have got very different sizes
and shapes.
 Angiosperms have got fruits which contain the
seeds, so the seeds are protected and they can
spread easily.
 Angiosperms have got brightly coloured flowers.
The flowers attract animals and so they help
pollination. The flowers are hermaphrodite mainly.

The plants cells group together into tissues, and tissues group together into organs. All plants have got
three parts or organs: leaves, stems , and roots.
LLeeaavveess
Leaves are mainly green and have got different shapes.
In leaves take place the photosynthesis and the change
of gases with the environment.
Leaves have got two parts:
 TThhee llaam
miinnaa oorr bbllaaddee
It is the biggest part of the leaf and has two
different surfaces, the front part or topside, and
the back part or underside. Inside the underside
part of the lamina there are a lot of tiny pores
called stomata. Gases and water vapour enter
the leaf and are expelled through the stomata.
 TThhee ppeettiioollee
It is the stalk that joins the leaf to the plant’s
stem
TThhee sstteem
m
Plant stems are usually above ground but some stems
grow bellow ground level.
The stem has four main functions which are:
 It keeps the plant upright and supports the
leaves, flowers and fruits.
 The stem keeps the leaves in the light.
 It transports fluids between the roots and the
leaves.
 The stem stores food and water. For example,
the potato acumulates reserves of water and
food.
The stem is normally divided into nodes and
internodes. Leaves and branches are joined to the stem
at the nodes. The internode is the area of a stem
between two nodes.
Stems grow upwards from the apical bud. Lateral
branches grow out of auxilliary buds along the stem
TThhee rroooott
The root is the part of a plant that is underground and grows downwards into the ground.
The two functions of the root root are:
 A
Abbssoorrppttiioonn of water and inorganic nutrients or mineral salts.
 A
Anncchhoorriinngg of the plant body to the ground.
Roots often contain food, such as the carrot or the sugar beet.
The root surface is covered with many tiny hairs which absorb the water and mineral salts.
The root has got a branch structure. It has a main root with secondary roots.
Each root ends in a root cap.

Flowers are the reproductive organs of angiosperms
The parts of a flower are as follows:
 PPeedduunnccllee.. It is the part that joins the flower to the stem.
 C
Caallyyxx. It is made of little green leaves called sepals.
They are in the base and protect the flower before it
opens when it is still a bud. When the flower opens you
can see the sepals behind the petals.
Sepals are usually green or brown, although in some
plants they are the same colour as the petals.
 C
Coorroollllaa. It is made of little brightly coloured leaves
called petals.
They are coloured to attract insects, such as bees or
butterflies, into the flower. The insects pick up pollen
from the flower, and carry it to the next flower they visit.
This is how most flowers are pollinated.
Not all flowers have got brightly coloured petals. Some
plants have got small flowers with no colour. This is
because they are not pollinated by insects or other
animals, but the wind. The wind blows their pollen grains
to other plants.
 SSttaam
meennss. They are the male reproductive
organs. Each stamen has got a thin stalk or
filament with an anther at the end.
Each anther is made up of pollen sacs,
which contain grains of pollen.
Pollen contains the male gametes.
 PPiissttiill.. It is the female reproductive organ
where the seeds are made. It has three
parts: the stigma, the style, and the ovary.
 The ssttiiggm
maa is the receptor of
pollen. It is covered in a sticky
substance. Its job is to catch the
grains of pollen (which usually
come from another flower)
 The ssttyyllee is the stalk that holds up
the stigma and is the way for
pollen tubes.
 The oovvaarryy contains one or more
tiny bodies called ovules or
“eggs”. Each ovule contains a female gamete or sex cell.
When the flower is pollinated, the pollen sticks to the stigma. It then travels down the style to the
ovary. In the ovary, the male gametes of the pollen joins with the ovules, and the ovules become
seeds. This is called fertilisation.
After fertilisation, the ovary turns into the fruit.

It is the transfer of pollen from the anther of a flower to the stigma of another flower.
There are two kinds of pollination: Through the wind or through animals.
 W

 A
Anniim
maall ttrraannssppoorrtt. Insects carry pollen in their legs or bodies and take it to other flowers
FFeerrttiilliissaattiioonn
The grain of pollen gets the pistil of a new flower. It sticks the stigma and forms a pollen tube. The tube
grows down through the style and enters an ovule. There the male and female gametes fuse together.
Then the fertilised ovule becomes a seed.
Afterwards the calyx and the corolla dry and fall, the ovary ripens into the fruit. The ovules are
transformed into seeds inside the fruit.
The fruit job is to protect the seed and help its dispersal carrying the seed or seeds.
D
Diissppeerrssaall oorr ddiisssseem
miinnaattiioonn
When fruits or seeds are mature, they split from the plant and scatter, or releases the seeds. The fruits and
seeds are scattered by animals, by the wind, and by the water. This process is called dispersal.
G
Geerrm
miinnaattiioonn
When the environment conditions are right, the seeds germinate on the ground: The seeds swell and
break and the embryo begins to grow into a new plant.
