Carolus Linnaeus (1707—1778),
seorang dokter dan penyelidik alam
berkebangsaan Swedia yang sangat
tertarik pada ilmu tumbuh-tumbuhan.
Beliau mengembangkan suatu metode
binomial nomenclatur atau sistem tata
nama ganda. Metode ini digunakan
untuk tata cara pemberian nama
makhluk hidup. Dasar yang digunakan
adalah persamaan struktur tubuh,
(struktur tubuh luar maupun dalam)
khususnya struktur alat reproduksinya.
Karena jasanya tersebut, Linnaeus
dijuluki sebagai Bapak Taksonomi.

Berdasarkan bentuknya bakteri dibedakan
menjadi 3 macam yaitu:

II. Blue Algae
Ganggang biru (Chyanophyta).
a)Characteristics of Blue Algae
 Often called Cyanobacteria
 The simplest algae
 The body is monocellular or multicellular and some live in colonies
 Have chlorophly so they can make photosynthesis process
b) Kinds of blue algae :
 Polycystis is a blue alga which lives in colonies
 Chroococus and gleocapsa are monocellularblue algae
 Oscillatoria rivularia and nostoc are blue algae which are thread shaped
(filament).

All organism which are included into the kingdom protista have eukaryotic
cells. Besides, they commonly have properties between plants and animal.
Kingdom protista is devided into 3 groups, namely :
 Plant like Protists
Example : Ganggang bersel satu soliter, contohnya Chlorella, ganggang
bersel satu koloni contohnya Volvox, dan Ganggang bersel banyak ada yang
berbentuk benang misalnya Spirogyra.
 Animal like Protists
Example : Rizhopoda (contoh: Amoeba), Cilliata (contoh: Paramaecium),
Flagellata (contoh: Euglena), dan Sporozoa (contoh: Plasmodium,
penyebab malaria)
 Fungus like Protists
Example : golongan jamur lendir (Myxomycota).

Plant like protists are known as algae. They are like plants because
they have cholorophyl so they can photosynthesize.
A. The characteristics of algae are as follows :
 They are monocellular or multicellular organism that are filament
shaped and same are like higher level plant with body organs
almost like roots and leaves
 Algae have no root, steam, and leaf so they are not included in
plant
 Commonly live in water,whether in sea water or fresh water. Some
live on land and usually in humid places, for example on a wall,
tree skin, or on the roof.
 Algae are used by humans as a nutrition source, fertilizer source,
various valuable commodities, for dishes, and hand cream

B. Algae are distinguished into several phylum
as follows :
 Phylum Chrysophyta ( Golden Algae )
 Phylum Chlorophyta ( Green Algae )
 Phylum Phaeophyta ( Brown Algae )
 Phylum Rhodophyta ( Red Algae )
 Phylum Euglenophyta

Animal like protists are know as protozoa. Protozoa are
usually found in ditches, rivers, or sea water, and some
live inside another organism. They reproduce asexually
by dividing it self or forming spores, and sexually by
conjugation.
Based on their movement method, protozoa are
grouped into four phylum as follows :
 Phylum Rhizopoda
 Phylum Flagellata
 Phylum Ciliata
 Phylum Sporozoa

14. Jenna Hellack Fall 2000
Contents
Organisms which are included into this group
are characteristics by a moving phase like
Amoeba, the reproduction method which is
almost like fungus, and the absence of
cholorophyll. The example are :
Mucus fungus ( Myxomycetes)
Water fungus ( Oomycetes)

A. Characteristics Of Fungi
 Have a nucleus and cell wall (eucaryotic).
 Have Spores
 Have no chlorophyll so they are heterotrophic.
 They are in the form of a cell or branched thread.
 The cell wall is of cellulose or chitin or both
 Bread sexually and asexually
 Live in rubbish, rotten wood, or rotten food with enought
humidity.

B. Fungi terdiri atas 4 divisio yaitu: Zygomycota, Ascomycota,
Basidiomycota dan Deuteromycota.
a. Zygomycota, contoh Rhizhopus oryzae, digunakan untuk
pembuatan tempe.
b. Ascomycota, contoh Saccaromyces cerreviceae, digunakan dalam
pembuatan minuman beralkohol. Contoh lain adalah Penicillium
notatum jamur penghasil zat antibiotik yang dikenal dengan
penisilin, dan Penicillium camemberti (bahan pembuat keju)
c. Basidiomycota, contoh Volvariella volvacea sering dikenal dengan
jamur merang, dan Auricularia polytrica (jamur kuping)
d. Deuteromycota, contohnya Rhyzoctonia solani, menyebabkan
penyakit pada Solanum sp (kentang).

C. The role of fungi in everyday life
Fungus which are beneficial are as follows :
 As agent (materials) in food making
 As antibiotic producer
 As decomposer in the ecosystem
Fungi which are harmful are as follows :
 Amanita phalloides causes distrubance in the kidney,
skin, and heart.
 Pneumonia cariini causes lung disease
 Epidermophyton causes skin fungus on humans.
