This document provides information about the plant kingdom and plant classification. It discusses the two main categories of plants - flowering plants (angiosperms) and non-flowering plants (gymnosperms, ferns, mosses). Flowering plants reproduce through seeds and flowers, while non-flowering plants reproduce using spores. The document also describes the key parts of plants - roots, stems, leaves and flowers. It explains the processes of photosynthesis, where plants produce their own food, and respiration, where plants both produce and consume oxygen.

THE PLANT KINGDOM

2.  PLANTS
CLASSIFICATION OF PLANTS
Flowering plants
Non-flowering plants
Angiosperms
Gymnosperms
Fens
Mosses

3.  Sexual reproducion. Flowers are their reproductive organs.
They reproduce through seed.
FLOWERING PLANTS
ANGIOSPERMS
Pollinated flowers produce fruits
whith seeds inside.
Examples: roses, cherry trees,
blackberries, rice….
GYMNOSPERMS
They have small flowers, they
don´t produce any fruits and
their seeds develop in cones.
Many of them, such as pine
trees, have long thin leaves
alleld needles.

4.  They do not produce seeds. They reproduce asexually using
spores.
NON-FLOWERING PLANTS
FERNS
They have roots and strong
stem under the ground. Their
leaves are called fronds. They
produce spores inside sori on
the underside of the fronds.
MOSSES
They have simple stems
and leaves. Their roots are
called rhizoids. They
produce spores inside
capsules.

5. PARTS OF PLANTS
ROOTS
They hold the plant in the
groung. They absorb water and
minerals from the ground
through the roots hairs
LEAVES
They contain chlorophyll. Most
leaves have two parts: the
petiole and the blade. Veins in
the blade support the leaf
And carry water and minerals.
On the underside of the blade,
there are tiny holes, called
stomata, where the gas
exchange takes place.
FLOWER
STEM
It holds up the
other parts of the
plant. It also
transports water
and minerals to
the leaves for
photosyntesis.

6.  Plants make their own food through the process called
photosynthesis
 1. The roots absorb water and minerals from the soil.
 2. Xylem cells transport this mixture of water and minerals,
caled raw sap, though the stem to the leaves.
 3. Leaves absorb carbon dioxide though their stomata. In the
cloroplasts, chlorophyll ccollets solar energy to transform water
and minerals and carbon dioxide into glucose and oxygen.
 4. Pholem cells carry the glucose, the plants´food though the
stem to all the parts of the plant.
PLANT NUTRITION

7.  Is very important because:
 1. It gives us oxygen to breathe.
 2. It consumes carbon dioxide.
 3. It transforms water and minerals into food. Animals can
feed on plants to get energy to live.
PHOTOSYNTHESIS

8.  Plants consume oxygen and produce in too. Plants produce
oxygen through the photosynthesis during the day. They
produce more oxygen than they need and expel it through the
stomata. At night, when photosynthesis stops, plants release
carbon dioxide.
