Prokaryotic cell Flashcards
(12 cards)
What is the basic structure of a prokaryotic cell?
Prokaryotic cells have a plasma membrane that separates the inside from the outside . Many also have a rigid cell wall made of peptidoglycan
What does the cytoplasm of a prokaryotic cell contain?
The interior of the cell, called the cytoplasm, contains a jelly-like fluid called cytosol where cellular components float
Where is the genetic information located in a prokaryotic cell?
Prokaryotic cells have a nucleoid region where their genetic information (a chromosome or set of chromosomes) is located
What are ribosomes responsible for in prokaryotic cells?
Ribosomes are responsible for building proteins based on instructions from genes
What is the typical size of a prokaryotic cell?
The size of prokaryotic cells is around a hundredth of a millimeter in diameter
What type of organisms are made up of prokaryotic cells?
Prokaryotic cells are unicellular organisms, like bacteria and archaea
How do prokaryotic cells compare to eukaryotic cells?
Eukaryotic cells make up multicellular organisms like humans
How do prokaryotic cells typically reproduce?
Through a process called binary fission.
What is the primary function of the prokaryotic cell wall?
To provide structural support and protection to the cell.
What are some common shapes of prokaryotic cells?
Cocci (spherical), bacilli (rod-shaped), and spirilla (spiral-shaped)
Can prokaryotic cells have flagella? If so, what is their purpose?
Yes, some prokaryotic cells have flagella for motility.
What are plasmids, and where are they found in prokaryotic cells?
Plasmids are small, circular DNA molecules found in the cytoplasm, separate from the main chromosome.
