Organization of procaryotic and eucaryotic cell Flashcards
What kind of cells are prokaryotes?
Prokaryotes are single - called organisms that are are the earliest and most primitive forms of life on earth
Example of prokaryotes?
Bacteria and archaeans
In what environments do they trive?
In extreme environments including extreme habitats such as hydrothermal vents, hot springs, swamps, guts of animals
Organelles of procaryotic cell
1.Capsule
2.Cell wall
3.Cytoplasm
4.Fimbriae or pili
5.Cell or plasma membrane
6.Flagella
7.Ribosomes
8.Plasmids
9. Nucleiod region
Size: 1-10 nano
Capsule - P - KAPSULA
Found in some bacterial cells, this additional outer covering protects the cell when it is engulfed by other organisms, assists in retaining moisture and helps the cell adhere to surfaces and nutrients.
Cell wall - P - CELIČNA STENA
The cell wall is an outer covering that protects the bacterial cell and gives it shape
Cytoplasm - P - CITOPLAZMA
a gel-like substance composed mainly of water that also contains enzymes, salts, cell components, various organic molecules
Fimbriae or pili - P - FIMBRIJE
Hair like structure on the surface of the cell that attach to other bacterial cells. Shorter pili called FIBRIAE help bacteria attach to the surface
Cell or plasma membrane - P - CELIČNA MEMBRANA
It surrounds the cell’s cytoplasm and regulates the flow of substances in and out of the cell.
Flagella - P - BIČEK
Long, whip-like protrusion that aids in cellular locomotion
Ribosomes - P - RIBOSOMI
Cell structures responsable for proteine production
Plasmids - P - PLAZMID
Gene carrying circular DNA structures that are not involved in reproduction
Nucleoid region - P - NUKELOID
Area of the cytoplasm that contains the single bacterial DNA molecules
How do prokaryotes reproduce?
Asexually, process is called BINARY FISSION
