Many of the know tress and flowers come from while other species of plants thrive in the tropical
rain forests some plant have adapted to live in or below water whereas some
have desert areas algae lichen and moss also belongs to the plant Why Are Flowering Plants The Most Successful Land Plant.
Different species of plant but they estimate this number to be
much higher today scientists are aware of around 320,000-500,000.

Unlike the thin and flexible stalks or stems of the shrubs
tress have thick stems of bear the load the heavier and bigger liver beaches
and fruits since trees are taller they and transport water from the soil much
further up than shrubs this is done by several thin hair like piper in the stem
and the beaches.
The main different tress and shrubs is their size tress are
much taller than shrugs and their root balls system or roots with attached soil
that supports the health of the tree are also bigger Why Are Flowering Plants The Most Successful Land Plant.
How do we different between plant species
The green plant include the green plant algae and the land
plants which grow thwarts lings against the earth gravity the land plant
include the mosses the vascular plant such and horsetails the seed plants these
also include the conifers gymnosperms and the flowering plants angiosperms.
Earlier the scientists different plants mainly by their
appearance plant are classified
according to their evolution ie on the basic that all member of a group must
have shared a common ancestor more recently than they have with any species
outsides the groups thus the plants are broadly classified as those containing
chlorophyll.
What are the types of plants
- Brown Algae
- Red Algae
- Horn-wort
- Liverworts
- Moss
- Club moss
- Horsetails
- Ferns
- Ginkgo
- Conifers
- Cotyledon dons
- Dicotyledons
- Gymnosperms Angiosperms Seed Plants
what are the main types of algae that exist
Algae are plant like living organisms they live the seas
fresh water or damp land areas they range from tiny single celled organisms
which can be seen only under a microscopes to larger plant like plankton used
the food by blue whales or flamingos large leaf like algae known as seaweed
grow extensively in shallow waters to form dense underwater forests.
Why should liches be protected
If your step on them you may destroy in seconds a plant that
look hundred of years to grow since lichens are very sensitive to air pollution
they are often used as pollution indicated the cleaner the air the more lichen
will grow.
Many lichens grow in inhospitable terrain for instance in
the rocky highland and cold arctic they also grow on the walls of the house in
big cities the growth rate are bacteria and viruses animals or plant
They belongs neither to the animals which are multi cellular
organisms nor to the plant which always have cell nucleus while most viruses
make humans animals and plants sick many bacteria are good.

What are the main types of algae that exist |
Bacteria are single cell organisms without the cell nucleus
viruses are only nucleic acid molecules in a protein coat For example bacteria
in the gastrointestinal track help in digestion whereas others like salmonella
cause disease.
Why do deciduous trees shed their in autumn but conifers do
not shed their needles if the leaves are not shed before winter the water will
continue to evaporate and the plant will dry up moreover the leaves can becomes
brittle with frost and crack therefore the deciduous trees shed their leaves as
a precautionary measure in contrast the needles of the conifers are leathery
and small and there is very little evaporation through them the needles are
also frost proof and stop their growth in winter.
Deciduous trees lose a lot of water through evaporation form
problem since the roots soak in enough water form the soil but in winter this
is not possible because the soil id frozen Why Are Flowering Plants The Most Successful Land Plant.
How are annual rings formed in trees
By autumn they becomes darker and thicker so the trees
becomes stable and resistant to frost in the winter rest period the process
this process forms a bright ring and a dark ring around the heartwood every
year if you count the dark rings of a horizontal cross section of the tree
trunk you can find out the age of the tree in the tropics.
When trees grow they accumulate wooden fibers around their
heartwood these fibers are brihg and porous in spring so that a lot water can
reach the fresh leaves through them.
Higher plant or the seed plants with male and female sexual
organs have stamens with pollen and the stigma the on to the egg cell in the
ovary a fertilized egg ripens to become a fruits which contains the seeds.
Plants reproduce in a variety of ways many species build
side shoots for which new plant grow plants like mosses and ferns reproduce
with the help of spores which are distributed by the wind and grow to become.
How do roots help plants
The roots also anchor the plant firmly in the soil to
safeguard against uprooting due to wind and bad weather roots changes shape and
adapt depending on their environment shallow rooted plants such as pine trees
whose tap root grows deep in the ground are found at place great depths inside.

Roots absorb water and the dissolved nutrient salts form the
soil they also store the nutrients as a reserve that the plant can survive on
when the soil dries up.
The clownish enjoy the protection of the poisonous nettle
fibers of the sea anemone and the sea survives to the left over food of the fish the liches that live in
associated with a fungus and an alga are also good example of symbiotic
relationship through the close interaction between its symbiotic partners the
lichens are able to grow in places where they could never have existed alone.
