WHAT ARE THE MONERA, FUNGI AND PROTISTA KINGDOMS LIKE?

What are the characteristics of fungi?
Mushrooms, mould and yeast are all fungi. They have several characteristics in common.
Fungi bodies: Most fungi are multicellular organisms, but some are unicellular, like yeast and mould. Many multicellular fungi consist of a cap, a stem and a networkof hyphae, long tubular structures.
Reproduction: Fungi produce spores that are carried by the wind.
Nutrition: Fungi produce a substance which breaks down plant and animal matter. This enables the fungus to absorb the nutrients from the decaying matter.

What are the characteristics of monerans?
Monerans  are microscopic, but not all share the same characteristics.
Moneran shapes: Monerans are simple unicellular organisms; they don´t have bodies. The shape of the cell varies according to the type of organism.
Extremities: Some monerans have a tail that helps them to move around. Others don't move, they stay in one place.
Nutrition: Some monerans produce a substance that breaks down plant or animal matter: they are heterotrophs. This helps them to absorb nutrients. Other monerans make their own food, they are autotrophs.
Reproduction: Most monerans reproduce by dividing. That is, one cell becomes two separate cells.

What is the Protista kingdom like?

Algae and protozoa belong to this Kingdom. There is a wide variety of protists. Each type has specific characteristics.
Protists shapes: Protists can be unicellular or multicellular.
Reproduction: Protists reproduce in two ways. Some produce spores; algae cells divide into two.
Nutrition: Some algae contain chlorophyll and carry out photosynthesis to produce food. They are autotrophs. Others are heterotrophs.
Movement: Some, such as protozoa, don't move. Others move in different ways. Amoebas, for example, move with pseudopods, or false feet, but paramecium move using cilia.
