This power point presentation will enhance your knowledge about different types of algae,their occurrence and habitat. It is very useful for school projects and assignments. really excellent for curious biologists. Hope you all like it

1. Algae are --
Simple plant like organisms.
Have cell wall can photosynthesize.
Have holdfasts instead of roots.
Can grow anywhere.
Algae fossil date back 400million years.

2. Sewage can be treated with algae,
Algae are used for making jellies ,puddings and ice-
creams.
Algae can be used to make Biodiesel
Algae are used to capture fertilizer in runoff from farm
They help in pollution control.

3. ALGAE SHAPES
The life cycle of a species, are:
 Colonial: small, regular groups of motile cells
 Capsoid: individual non-motile cells
 Coccoid: individual non-motile cells with cell walls
 Palmelloid: non-motile cells embedded in mucilage
 Filamentous: a string of non-motile cells connected
together, sometimes branching

4.  There are many
different types of
algae .Some of
them are :
 Green algae
 Blue green algae
 red algae
Lokesh

5.  Green algae is
green in color
Great variety
forms-one celled,
simple or well
organized
colonies,simple or
branched
filament moving
or motile form
have flagella.

6. Blue-green algae are actually
bacteria. They are present in
soil ,water and
hotsprings.They produce
oxygen They can fix
nitrogen. They can flourish
in any environment. they
have phycobolin.Don,t have
flagella and reproduce by
binary fission.

7. Red algae are reddish or
purplish in color. There
are about 6,000 species of
red algae . Red algae are
simple one-celled
organisms to complex,
multi-celled, plant-like
organisms. Their cells lack
flagella.

8.  Green Algae live close to the
surface of sponge The alga
is thus protected from
predators; the sponge is
provided with oxygen and
sugars.
 The fungus of lichens have
a symbiotic relationship
with algae. The fungi
provide protection and
moisture to the algae, and
the algae feed the fungi
with photosynthetic
nutrients
