ALGAE :
Algae are simple plant- like organisms that have cell walls and chlorophyll within the cells. They make their own food by photosynthesis. They have no roots, stems or leaves.
Algae are autotrophic and live in water and at moist places, some algae are found in snow and some in hot springs.
Algae can be unicellular or multicellular.
USES OF ALGAE :
♣ In Medicine : Antibiotics are prepared from some algae like chlorellin.
♣ In Industry : Different Commercial products are obtained from algae like agar, sodium, Pottassium and iodine.
♣ As Food : Algae are rich in nutrients so eaten as salads and soups.
♣ In Agriculture : Some Algae ( blue- green algae) help in nitrogen fixation. Some sea weeds are used as Fertilisers.
♣ In space : In recent years, algae is used as source of oxygen in spaceships and also as food.

✌️✌️hey mate here is the answer...

economic importance:
➡️photosynthesis:
• at least half of the total carbon dioxide fixation on earth is carried out by algae through photosynthesis.
•being photosynthetic they increase the level of dissolved oxygen in their immediate environment.
•it is essential for respiration of aquatic life.
➡️Primary producers :
•algae are primary producers of energy rich compounds.
•This form the basis of food cycles of all aquatic animals.
➡️food supplements:
•many species of porphyra, laminaria and sargassum are among the 70 species of marine algae used as food.
•Certain unicellular algae like chlorella and spiral inner are rich in protein and are used as food supplements even by space travellers.
➡️hydrocolloids :
•hydrocolloids are water holding substances. certain marine brown and red algae produce large amount of hydrocolloids which are used commercially.
•algin and carrageen are hydrocolloids obtained from brown and red algae, respectively.
•agar is one of the commercial products obtained from gelidium and Gracilaria and are used to grow microbes and in preparation of Ice creams and jellies.
➡️iodine :
•fucus and laminaria are rich sources of iodine.
