Phylum Protozoa or Filum protozoa are single-celled animals that accept abandoned one corpuscle abandoned alias celled diminutive admeasurement can abandoned be apparent with a microscope. Protozoa can alive in baptize or in the active anatomy or added bacilli as parasites. Her activity can be abandoned or aloof or a assemblage or a colony. Examples: amoeba / amoeba. Allocation is the analysis of the kinds of active beings into groups ample and baby in a assertive order.
Taxonomy is a law or aphorism that divides the assorted groups of active creatures on the base of assertive criteria.
Nomenclature is the allotment procedures on active breed / groups that active things are organized in the classification.
In total, there are bristles kingdoms of active things in the world, namely:
a. Kingdom Monera; are unicellular / colonial and prokaryotic.
b. Kingdom Protista; are unicellular / colonial and eukaryotic.
c. Kingdom Plantae; are multicellular, eukaryotic, accept corpuscle walls.
d. Kingdom Fungi; are eukaryotic and no barrier amid cells.
e. Kingdom Animalia; are multicellular and eukaryotic.
Kingdom Animalia is disconnected afresh into three branches (branch), which is Parazoa, Mesozoa and Eumetazoa. Eumetazoa annex consists of analysis and the analysis Bilateria radiata based on anatomy appearance of organisms.
• prokaryotic> do not accept the corpuscle nucleus.
• Eukaryotic> accept a corpuscle nucleus.
Phylum Protozoa
Protozoa are bacilli that about renik single-celled, accept a anchored form, but some breed accept the anatomy appearance changes according to age or environment.
Tues protozoa of anatomy which is covered by corpuscle membrane. Anatomy itself consists of a base (cell nucleus) and cytoplasm (cell fluid). Cytoplasm is disconnected into cloth and ektoplasma. Cloth about added blurred blush because it contains the corpuscle organelles, while ektoplasma was afterpiece to the corpuscle film and added clear.
Protozoa accept no absolute organs and move with the motion instruments of flagel (fur whip), cilia (hairs vibrating), pseudopodia (false feet), or with the body's own cells. Tool motion identification base Phylum Protozoa.
Based on the motion devices, Protozoa subphylum is disconnected into three, namely Sarcomastigophora, Sporozoa and Ciliophora.
Based protoplasm, pseudopodia abide of four types, namely Lobopodia, filopodia, retikulopodia, and aksopodia. Based on the area and structure, cilia are disconnected into three kinds, namely bouncing membrane, membranella and cirrus.
Protozoan respiration action gas by circulation amid the corpuscle and its environment. Some breed accept a shell, analytical or spores that serves as the body's aegis adjoin ecology altitude are beneath conducive. Aegis accessories is about added endemic by the freshwater protozoan protozoans than sea water.
Mechanism of abdominal protozoa is not complicated. First, the aliment went through the cytostome (the aperture that served as the mouth). Then taken to cytopharink. Further digested aliment in the aliment vacuole. Digestion after-effects are appear from beef through cytopyge (cytoproct) (hole acting / abiding that serves as the anus).
Based on how to eat and the types of food, protozoa are disconnected into bristles types, namely holozoik (heterotrof), holofilik (autotrof), saprozoik (consuming aqueous substances), saprofitik (eating solid substances ahead ashen with aqueous from the protozoan cells), and mixotrofik ( alloyed type).
Protozoan reproduction with asexual and animal means. Protozoa can asexually carbon by fission into two individuals (binary fission), agreeable into abounding individuals (multiple fission) and pertunasan (budding) alien and internal. Sexually breeding protozoa with the abutment of two gami and alliance (for Ciliata).
Ecologically, protozoa can alive advisedly in nature, activity komensal, mutualistik life, as the aerial predators, and sessile (settled). In addition, abounding abject protozoa, both of plants, animals and humans.
