FUNGI

CHARACTERISTICS OF FUNGI:

-EUKARYOTIC
-SINGLE-CELLED OR MULTICELLULAR
-HETEROTROPHS (they can't make their own food because they don't have chlorophyll for photosynthesis)
-THEY HAVE A CELL WALL MADE OF CHITIN
-THEY GROW IN WET PLACES (they need humidity to grow)

TYPES OF FUNGI:

SINGLE-CELLED: YEASTS

Yeast are important because they cause fermentation  and are used to make various products such as bread, beer or wine

MULTICELLULAR: MOULDS AND MUSHROOMS

Their cells are grouped into filaments called hyphae. Moulds are very important in ecosistems because they are decomposers.
Mushrooms can be toxic or edible, some of them are a great source of nutrients and have excellent flavours like Boletus edulis or Amanita caesarea. Others are very poisonous and they can kill people like Amanita phalloides.

DIFFERENT TYPES OF BACTERIA

These are Cocci, they are spherical in shape. Cocci cause many bacterial infections in humans, such as strep throat, pneumonia, food poisoning, otitis media, various skin diseases, meningitis and severe types of septic shock.




These are bacillus, they are cylindrical in shape. Some are pathogens and cause diseases such as but others are beneficial and used to make yoghourt and other products.

Numerous enzymes, antibiotics and other metabolites have medical, agricultural, pharmaceutical and other industrial applications. Examples of antibiotics formed by Bacillus spp include bacitracin.

They form spores which are a method of surviving unfavourable conditions.



Spirilla are spiral shaped as you can see, they cause diseases like siphilis .




Finally vibrios are comma shaped bacteria, some of them, for example Vibrio vulnificus can cause serious illness when you eat seafood.
