1.KINGDOM MONERA
Kingdom monera consist of microorganisms which have no nucleus membrane (prokaryote) so the nucleus material is spread in the cytoplasm. Monera has nucleus acid (DNA), cytoplasm, and cell membrane. Monera consist of bacteria and blue algae.
a.Bacteria
Bacteria are procaryotic organism and small size which can only be observed by strong magnification using a strong microscope. The characteristic of bacteria are as follows.
1)Consist of one cell (unicellular)
2)The size is 4-8 micron
3)When they group (form colony), bacteria can be seen
4)Have no chlorophyll
5)Can live in various environment
6)Breed asexually by dividing itself and sexually by conjugation
7)If environment condition is bad, bacteria form spores which are called endospores. On the contrary, in suitable environment, bacteria will breed (divide themselves) fast.

b)Fungi reproduction
Fungi reproduce sexually and asexually. Asexually reproduction is by producing spores which begins with the formation of spore producing body, examples sporangium,ascus, basidium, or conidiophores. Sexual repropoduction is carried out by means of white, fine threads, which are able to make interthreads sexual union because their kinds are different.
c)Classification of Fungi
Based of their reproduction method, fungi are distinguished into 4 subdivisions as follows
1)Subdivision Zygomycota
An example of Zygomycota fungi is tempe fungus (Rhizopus) which has unpartitioned hypha. Another example is mycorhiza.
2)Subdivision Ascomycota
These fungi make spores in a bag (bowl)-shaped structure, so they are also called bag fungi. Some of these fungi are beneficial and some harmful. The beneficial fungi are used to make food, for example Neurospore is used to make ‘oncom’ and Saccharomyces cerevisiae ia used to make bread, ‘tape’, and sake (beer). The harmful fungi in ascomycetes are those which cause a disease in humans, animals, and plants. Some types of Ascomycetes also make symbiosis (associate) with algae to form lichens. Other examples of it are Panicillium and Aspergillus.
3) Subdivision Basidiomycota
The characteristic of fungi which are included into the subdivision of Basidiomycota are as follows
a)Have macroscope size
b)The hypha has a cross partition
c)Consist of a collection of mycelium threads which group to form a fungus bbody that is a fruit body
d)The shape is like an umbrella (cover)
e)Spores ae apread by the wind and if they fall to right place they will grow to be new hyphae
4)Subdivision Deuteromycota
Deuteromycota is a special group of fungus of which the sexual reproduction. The classification of fungi into this subdivision is temporally,because further research is being done. So a fungus which was formerly included into Deuteromycote then if it was found out to able to produce spores from the union process of its hyphas, the classification will change.
