1) Primitive atmosphere of the earth |
1) Nitrogen 2) Carbon dioxide 3) Ethane 4) Ammonia 5) Hydrogen 6) Hydrogen Sulfide (no oxygen) |
|
|
2) Oparin and Haldane Hypothesis |
1)Erth early atmosphere was reducing environment 2) Energy for organic synthesis was from lightning and UV radiation. Life appeared from early ocean "primitive Soup" |
|
|
Sources of energy for life on earth |
1)The Sun Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates |

Bacteria can be classified into two groups based upon the cell wall: |
1)Gram (+): Large amount of peptidoglycan and have a membrane |
|
|
2) Gram(-): -less peptidoglycan, more complex with an outer membrane containing lipopolysaccharides. And are more threatening because the wall are toxic and are resistant to antibiotic -Extract membrane( Lipopolysaccharide and protein, peptidoglycan, membrane) |
Gram (+) : stain purple, because they have a thick cell wall without an outer membrane. Gram(-): (stain,red/pink, because they have a thin cell wall with an outer membrane. |
|
|
Three basic shapes of bacteria 1) Coccus- cell are round/spherical shaped 2) Bacillus- Cell are rod-shaped 3) Spirillum- cell are spiral shape |
1) coccus
|
|
|
2) Bacillus
|
3) Spirillum
|
|
|
|
coccus is gram (+)
|
|
|
Cell can be variations of the above shapes coccus- group acording to arrangements: 3 basic shapes of bacteria(monphology) -Diplo-( two bolita) -Staphylo-( mucha bolita juntas,comunidad) -Strepto(muchas bolitas en linias) |
Arrangement of bacterial : coccus ( una bolita redonda una sola) -Bacillus ( como un candy largo retangulo) -spirillum(una snaked) |
|
|
streptococcus-pneumonia |
|
|
|
staphylococcus aureus |

|
|
|
Streptobacillus - Bacillus cereus |
special things it have a eyes on it |
|
|
Bacillus Anthracis (Anthrax) |
|
|
|
Anabaena: |
the hole is called heterocyst |
|
|
They are known for nitrogen-fixing abilities, and they form symbiotic relationships with certain plants, such as the mosquito fern. |
Cyanobacteria-Autotrophic bacterial - photosynthetic -Phycocyanin- bluish pigment to capture light -chlorophyll a - Blue, red or pink bacteria ( oscillatoria, Anabaena, Gloecapsa) |
|
|
Gloeocapsa |
cookis |
|
|
vorticella- it have the shape of a flower and have a myoneme that its function is to help the vorticella to get shorter or bigger |
|
|
|
|
Unikont= Amoeba proteus (special thing) it have a pseudopods and its fuction it work as a arm to grap food for the amoeba. |
|
|
|
|
|
|
Archaeplastida (green plants, green algae) volvox ( special) it has daughter colonies that split up and daughter colony go out. |
|
|
|
|
|
|
|
Excavata: Trypanosoma cruzi (Chagas disease) it come out at night, eat blodd cells, it come from bugs, or tramplants (blood, orgams) (mexico) |
|
|
|
|
|
|
|
Euglena gracilis- special it have a eyespot, and flagellum, and it turn green when light appear. |
|
|
|
Chromalveolates: Peridinium( have a flagella in groove, thecal plates |
|
|
|
Rhizaria: Foraminifera it have a test(shell)it have calcium carbonate which make it brownish color |
|
|
|
Radiolaria :it have a test(shell) it made of silicon compound |
|
|
|
paramecium bursaria it have zoochlorella is agreen dots that producen extract sugar to be able to live inside the paramecium. As well when the paramecium dont get light it eats the zoochlorella and when it come to light it eat new zoochlorella. |
|
|
|
|
|
|
|
stentor coeruleus: it move slow moving or stagnant fresh water, sticky substance on narrow end cilia-motility and creates a whirlpool-like disorder in the wwater to gests the prey into the gullet corkscrew structure on outside of stentor.`1 |
