Prokaryotic cell
bacteria
Virus
a cellular, non-living structure which contains nucleic acid and is enclosed in a protective protein (capsid)
Plasmid
Possesses genes that may aid the survival of bacterial cells in adverse conditions(only in certain species)
Murein/pepridoglycan
Makes up the cell wall of bacterial cells
Mucilaginous
Protects bacteria cells
Flagellum
used for locomotion and there may be more than one (Only in certain species)
Structure of prokaryote
• no true nucleus, only a single circular DNA • DNA not associated with proteins • some DNA may be found in the form of circular strands called plasmids • No membrane bound organelles -Ribosomes are smaller (70s)
What size are ribosomes in a prokaryote
70s
Give two structures found in both prokaryotic cells and eukaryotic cells
-Ribosomes - Cell membrane -cytoplasm -DNA
Name an organelle found in both a chloroplast and a prokaryotic cell
-ribosomes
Name the main biological molecule in the cell membrane of a prokaryotic cell
Phospholipids
Name the main biological molecule in the cell wall of a prokaryotic cell
Murein
Name the process by which prokaryotic cells divide
Binary fission
Flagellum
used for locomotion and there may be more than one (Only in certain species)
