The document discusses bacteria, including their characteristics, shapes, and roles in causing common human diseases and providing benefits. It describes the three main shapes of bacteria - cocci, bacilli, and spirilla - and examples like streptococci and staphylococci. Major diseases caused by bacteria mentioned include acne from Propionibacterium acnes, tuberculosis from Mycobacterium tuberculosis, leptospirosis from Leptospira interrogans, and anthrax from Bacillus anthracis. The document also notes benefits of some bacteria, like Streptomycin used as an antibiotic and Lactobacillus bulgaricus in producing yogurt.
Cyanobacteria as a Biofertilizer (BY- Ayushi).pptxAyushiKardam
Cyanobacteria, also known as “blue-green algae”.
They are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see.
They are the most abundant group of organisms on the earth. They are autotrophic and found in a diverse environment, especially in the marine and freshwater.

Background
Biologists have long organized living things into large groups called kingdoms.
There are six of them:
Archaebacteria
Eubacteria
Protista
Fungi
Plantae
Animalia
Some recent findings…
In 1996, scientists decided to split Monera into two groups of bacteria:
Archaebacteria and Eubacteria
Because these two groups of bacteria were different in many ways scientists created a new level of classification called a DOMAIN.
Now we have 3 domains
Bacteria
Archaea
Eukarya
KingdomArchaebacteria
Any of a large group of primitive bacteria having unusual cell walls, membrane lipids, ribosomes, and RNA sequences, and having the ability to produce methane and to live in anaerobic, extremely hot, salty, or acidic conditions
The Domain Archaea
“ancient” bacteria
Some of the first archaebacteria were discovered in Yellowstone National Park’s hot springs
Prokaryotes are structurally simple, but biochemically complex
Basic Facts
They live in extreme environments (like hot springs or salty lakes) and normal environments (like soil and ocean water).
All are unicellular (each individual is only one cell).
No peptidoglycan in their cell wall.
Some have a flagella that aids in their locomotion.
Most don’t need oxygen to survive
They can produce ATP (energy) from sunlight
They can survive enormous temperature extremes
They can survive under rocks and in ocean floor vents deep below the ocean’s surface
They can tolerate huge pressure differences
STRUCTURE
Size
Archaea are slightly less than 1 micron long.
A micron is 1/1,000 of a millimeter.
In order to see their cellular features, scientists use powerful electron microscopes.
Shape
Shapes can be spherical or ball shaped and are called coccus.
Others are rod shaped, long and thin, and labeled bacillus.
Variations of cells have been discovered in square and triangular shapes.
STRUCTURE
Locomotion
Some archaea have flagella, hair-like structures that assist in movement.
There can be one or many attached to the cell's outer membrane. Protein networks can also be found on the cell membrane, which allow cells to attach themselves in groups.
Cell Features
Within the cell membrane, the archaea cell contains cytoplasm and DNA, which are in single-looped forms called plasmids.
Most archaeal cells also have a semi-rigid cell wall that helps it to maintain its shape and chemical balance.
This protects the cytoplasm, which is the semi-liquid gel that fills the cell and enables the various parts to function.
STRUCTURE
Phospholipids
The molecules that make up cell membranes are called phospholipids, which act as building blocks for the cell.
In archaea, these molecules are made of glycerol-ether lipids.
Ether Bonding
The ether bonding makes it possible for archaea to survive in environments that are extremely acidic or al

Cyanobacteria are photosynthetic group of bacteria that can fix atmospheric nitrogen essential for aminoacid biosynthesis. Earlier they were called as blue green algae. Now that name is not used because they are not belongs to the algae.

Eubacteria are the most commonly found organisms in the world. They are also known as true bacteria, and are present on almost all surfaces. They are prokaryotic cells, and hence do not have a nucleus. The eubacteria kingdom is one of the six kingdoms in which the entire living world is classified.
Students, digital devices and success - Andreas Schleicher - 27 May 2024..pptxEduSkills OECD
Andreas Schleicher presents at the OECD webinar ‘Digital devices in schools: detrimental distraction or secret to success?’ on 27 May 2024. The presentation was based on findings from PISA 2022 results and the webinar helped launch the PISA in Focus ‘Managing screen time: How to protect and equip students against distraction’ https://www.oecd-ilibrary.org/education/managing-screen-time_7c225af4-en and the OECD Education Policy Perspective ‘Students, digital devices and success’ can be found here - https://oe.cd/il/5yV
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

4. Eubateria characteristics
1.Cell wall
2.True bacteria
3.Cannot survive in extreme environment
Cell wall are made of
1.Peptidoglycan- is responsible for
the rigidity of bacteria
2. Carbohydrate – they only on the
extracellular side of cell wall
16. • This bacteria are present in
the urine and tissues of cattle pigs,
horses, dogs, rats and wild animals
• Larges number of leptospira bacteria
are in the urine of rats
20. Used as antibiotic (Streptomycin) is an antibiotic drug,
the first of class of drug, and it was the first
effective treatment for tuberculosis
21. E. Coli or Escherichia Coli naturally found in the large
intestine of humans. These bacteria meanwhile
provide the much needed vitamin B12
22. Lactobacillus bulgaricus and Streptobacillus thermophilus
Theses are specially involved in making sour milk or
Yogurt. Lactase in the bacteria changes the milk sugar into
Lactic acid, which gives yogurt its semi-liquid texture.
