The Fungi Kingdom is made up of a variety of different fungi. For many years, it was believed that fungi were plants. Today we know that fungi are different from plants in some very important ways. First, unlike plants, fungi cannot make their own food. They must rely on other food sources to support them. There are also differences in the basic makeup and chemistry of their cells.

FUNGI KINGDOM Some fungi such as yeasts. Which are used to

make bread and beer, are micro-organisms and can only been under the microscope. Other fungi start from microscopic filaments which grow bigger and bigger until we can see them with our eyes..

Mushrooms and toadstools are the reproductive part of the fungus, or fruiting body. They produce millions of spores which, when dispersed, grow to make a new fungus, a bit like seeds in the

apple.

Monera Kingdom consists of unicellular life forms. Unicellular means that they only have one cell. Monera are classified into two phyla, or groups, Autotrophs and Heterotrophs. Autotrophs are able to create their own food, similar to plants. Heterotrophs cannot create their own food, and so must rely on autotrophs as their food source.

Bacteria is in the group of Monera Kingdom.

Bacteria are the simplest of creatures that are considered alive. They are very simple cells that fall under the heading prokaryotic. That word means they do not have an organized nucleus. Bacteria are small single cells whose whole purpose in life is to replicate.  Some bacteria help plants absorb nitrogen (N) from the soil. Some cause diseases like botulism. Some bacteria even live inside the stomachs of cows to help them break down cellulose.

The Protista Kingdom consists of unicellular life forms (life forms with only one cell) who have a nucleus. Many protists appear to be both plant and animal. Like plants, they are green, and can create their own food. However, like animals, they have moving body parts and are able to move around their environments.

Protozoa is in the Protocista Kingdom.

PROTOCISTA KINGDOM

 The protozoa (proto = first, zoa = animals). Protozoa are the oldest known group of heterotrophic life that consume and transform complex food particles into energy. Although protozoans are only made up of a single cell, these organisms manage to perform all the basic tasks of life.  The protozoa are divided into four major groups: the ciliates, the flagellates and the amoebas.

Amoebas: These protozoans are constantly changing shape; they look and move much like balloons half filled with water.They can create extensions of their body wall called pseudopodia that help them locomote or capture prey or simply churn up their insides to distribute nutrients.

Flagellate: Similarly complex single-celled organisms, flagellates have whip-like appendages called flagella sticking out of their cells. The flagella are used for locomotion and to direct food particles or cells into the organism’s mouth-like opening. Flagellates dine on bacteria, algae, and other protozoa.

Ciliates : Ciliates are generally considered the most evolved and complex of protozoans. Ciliates are single-celled organisms that, at some stage in their life cycle, possess cilia, short hair like organelles used for locomotion and food gathering.
