Presentation on theme: "MONERA KINGDOM. UNICELLULAR PROKARYOTIC ORGANISMS Characteristics: O They are single-celled organisms O They DO NOT have nucleus. O They are prokaryotic."— Presentation transcript:
TYPES OF BACTERIA: O Coccus: spherical bacteria O Bacillus: Rod shaped bacteria O Vibrio: Curved bacteria O Spirillum: Bacteria with a helical or spiral shape
What type of bacteria is the letter ´ a `? O The letter `a ´is a ________
The vital functions of bacteria: NUTRITION: O Most bacteria are heterotrophic, but some of them are autotrophic. O They feed in different ways: O Saprophytes:. these live on decomposing organic remains. And they become inorganics substances. In this way they enrich the soil O Parasites: They feed on other living being, harming them and causing infectious illnesses. O Symbionts: They live in close association with another living things and this produces a mutual benefit such as those which live in our intestine.
The vital function of bacteria: REPRODUCTION: O Bacteria reproduce asexually through successive cell divisions. INTERACTION: O Some of theses organisms do not move. Some swim by means of flagella and other slide over surfaces. http://www.youtube.com/watch?v=BHx078zOeiM O They can live in all types of environments.
CYANOBACTERIA also known as blue-green algae that obtain their energy through photosynthesis. They are autotrophs.
Characteristics O They are unicellular organisms O They are heterotrophs The vital function of Protozoa: O NUTRITION: O They are heterotrophs. O They feed in different ways: O Hunters: they feed on micro-organisms O Parasites: They feed on other living things, harming them and causing illnesses such as malaria. O REPRODUCTION: They repoduce by dividing their cellular body into two daughter cells O INTERACTION: Most move using differents mechanisms: Using a flagellausing pseudopodsusing cilia TrypanosomaAmoebaParamecium
3. Two daughter ameba are produced. 2. The ameba becomes thinner in its centre. Ameba (mother) 1. The ameba grows and its components duplicates. Daughter ameba
Characteristics O They are unicellular and they usually form colonies O They can be multicellular orgnisms but they never form tissues O They are autotroph. They perfom photosynthesis O Most are aquatic from fresh water and salt water.
Classification O Brown algae O Green algae O Red algae
Characteristics O They are eukaryotic heterotrophic organisms O Some are unicellular and other are multicellular, but they never form tissues. O Their cells have cellular wall, but they are different to plant cells
Some multicellular fungi are made up of fine threads called hyphae. When hyphae are packed together, they form the mycellium
Vital function O NUTRITION: 1. Saprophytes: Feed on remains of dead organisms, like remains of plants of animals. musrhooms 2. Parasites: Feed on living things causing them illnesses. Candida Parasites: 3. Symbionts. Feed by associating with autotrophic organisms provide them with food they need. lichen
