Слайды и текст этой презентации
Слайд 2Bacteria constitute a large domain of
prokaryotic microorganisms. Typically a few micrometres in length, bacteria have
a number of shapes, ranging from spheres to rods and spirals.
Слайд 3Morphology
Bacteria display a wide diversity of shapes and sizes, called morphologies.
Bacterial cells are about one-tenth the size of eukaryotic cells
and are typically 0.5–5.0 micrometres in lengthBacteria display many cell morphologies and arrangements
Слайд 4 Bacteria often attach to surfaces and form dense aggregations called biofilms or bacterial
mats. These films can range from a few micrometers in
thickness to up to half a meter in depth, and may contain multiple species of bacteria, protists andarchaea.
The range of sizes shown by prokaryotes, relative to those of other organisms and biomolecules
Слайд 5Cellular structure
Intracellular structures
The bacterial cell is surrounded by a lipid membrane. This
membrane encloses the contents of the cell and acts as
a barrier to hold nutrients, proteins and other essential components of the cytoplasm within the cell.Structure and contents of a typical Gram positive bacterial cell
Слайд 7Antonie van Leeuwenhoek, the first microbiologist and the first person to
observe bacteria using a microscope.
Bacteria were first observed by the Dutch
microscopist Antonie van Leeuwenhoek in 1676, using a single-lens microscope of his own design
