In order for Plants to grow they need:
SUNLIGHT,
WATER and
AIR.


All plants
BREATHE,
GROW,
REPRODUCE and
FEED.


All plants can be put into one of two groups:
1) Flowering Plants
2) Non-Flowering Plants


NON-FLOWERING PLANTS
There are 4 types of non-flowering plants:
1) Mosses
2) Algae
3) Ferns
4) Fungi


FLOWERING PLANTS
These plants produce flowers and have stems, which are either SOFT or WOODY.
Soft-stemmed plants grow from bulbs or seeds
Woody stemmed plants are either shrubs or trees
Flowers open during the daylight hours



PLANT PARTS AND THEIR FUNCTIONS

Here are the parts of a flower:






















The Petals attract insects to the flower.

The Leaves collect sunlight and moisture and produce energy for the plant.

The Stem supports the flower.

The Roots anchor the plant in the soil and they take in moisture and nutrients from the
soil.


REPRODUCTION
A plant won't live forever, so it has to make new plants. This is called REPRODUCTION.
The job of making new plants is done by the flowers.

The stages of Reproduction in a flower:
1) A flower's colourful petals and scents attract insects to it in their hunt for nectar
2) As the insects are feeding they brush against the stamens and pick up pollen
3) The pollen is brushed onto the stigma when the insect lands onto another plant
4) The pollen grain goes down the stigma to the centre of the ovary
5) Fertilisation takes place in the ovule / ovary
6) Seeds form inside the ovule
7) Seeds are dispersed
8) New plants develop from the seeds.


SEED DISPERSAL
Seeds can be dispersed in different ways:
1) Wind
Seeds are blown away
2) Animals
Eat fruit and pass seeds as droppings
Seeds catch on animals fur and fall off at another place
3) Explosion
Seeds are exploded from the flower into the air
4) Water
Some Seeds float in rivers to other locations


PLANT GROWTH
The lifecycle of a plant changes according to the season. Spring and Summer are the
times of most rapid growth for plants. Autumn and Winter are times when plant growth
slows and a dormant (sleep) period follows.
Plants grow quicker in the Summer because there is more sunlight and warmth.
