Algae have a thin,
Cell wall solid cell mem-
brane and a com-
plex nucleus. The
chlorophyll is pro-
Mitochondrion tected with a spe-
Nucleus cial membrane that
carries out the

life. Algae also clean
the water they live in.
Some have constructive
properties that actually
change the form and nature of
the shore and sea beds. Providing
food and nutrients for living things, they constitute the basis of the
food chain in the oceans.
Some algae use light and CO as their basic fuels. Others feed

by producing complex organic substances from simple ones. For ex-
ample, the energy from the Sun reaching the surface of the Atlantic
Ocean on a summer day is around 2 billion calories. Some 99.5% of
this energy is reflected and scattered. Only 1.67 million grams
(0.5%) is used by single-celled algae to produce food. Algae absorb
32% carbon dioxide and dissolve and expel the remaining 8% in the
70
form of organic substances. That level of 8% is needed by the plan- HARUN YAHYA
et as organic matter, which is transmitted to other living things.
Algae are used by industry in many ways—directly in the
manufacture of foodstuffs, drugs and other industrial products,
and also play a significant role in the manufacture of other goods. (ADNAN OKTAR)
These products are in turn used to manufacture various foods,
