2. There are two types of plants:
Non-flowering plants
Flowering plants
spores
1.- Non-flowering plants.
The non-flowering plants do not produce flowers. They
normally reproduce by spores.
Spores are tiny organisms that only contain a few cells.
Plants that make spores produce huge numbers of them.
Because they are so small and light, they can be dispersed
by the wind to new locations where they can grow.
3. 1.1- Moss and fern
Mosses and ferns are the most important types of non-
flowering plants.
• Mosses are soft and spongy plants that typically only
grow a few inches tall. They tend to grow together in
clumps. Mosses don't have flowers or seeds, but use
spores to reproduce. They also don't have typical
roots like most plants, but anchor themselves to rocks
and soil with short growths called rhizoids.
Mosses tend to grow in damp areas with plenty of
shade.

4. Ferns produce spore which are
inside casings underside of their
leaves. These look like brown spots.
At some point the casings dry out
and the spores are released into the
air. Unlike mosses, ferns have got
roots
Scientists estimate that some
species of ferns have been around
for over 350 million years.

5. 2.- Flowering plants
Flowering plants are a type of plant that
produces flowers in order to reproduce.
Flowering plants produce seeds within a fruit.
The scientific name for flowering plants is
angiosperms.
Flowering plants follow a specific life cycle:
Seed - They begin their lives as seeds. Seeds
are like baby plants. They have a hard outer
shell that protects the seed embryo inside.
Germination - The seed ends up on the ground.
It needs air, water, and soil to grow. When a
seed begins to grow, this is called germination.
The first growth will usually be some small
roots. Then stems will grow.
6. Sprout or seedling - When the first
sign of life appears above the soil,
this is called a sprout or seedling.
Mature plant - The seedling will
continue to grow into a full mature
plant with leaves, roots, and stems.
Flowering - The mature plant will
grow flowers. Through pollination, the
flowers will produce seeds. When the
seeds end up on the ground, the cycle
will begin again.
