16
Q

differentiation

A

process which cell becomes more specialized , during this process some genes start to be used in function of cell; gene is expressed or unexpressed
differentiated cells- tissue- organs- organ system- multicellular organism

17
Q

prokaryotic cells

A

no nucleus no membrane, bound organelles DNA not inclosed inside nucleus but found in region called nucleoid eg bacteria, archea etc

18
Q

organelles

A

structures found inside cells perform specific functions

19
Q

organelles in a prokarayotic cell

A

pili, cell wall, plasma membrane, nucleoid containing naked dna, cytoplasm, 70s ribosomes, plasmid, flagella

20
Q

prokarayotic cell- plasma membrane

A

permeable membrane- control substances move in or out of cell

21
Q

prokarayotic cell- cell wall

A

made of peptidoglycan- maintains shape of cell prevent cell from bursting

22
Q

prokarayotic cell- pili

A

hair like structures- help bacteria adhere to eachother for transfer of DNA conjugation

23
Q

prokarayotic cell- cytoplasm

A

gel like enclosed in cell- has enzymes catalyse chemical reactions inside cell

24
Q

prokarayotic cell- flagella

A

whiplike structure- help bacteria move

25
Q

prokarayotic cell- ribosome

A

70s type- protein synthesis

26
Q

prokarayotic cell- nucleoid

A

region containing naked dna- DNA holds genetic info controls cell

27
Q

prokarayotic cell- plasmid

A

ring of dna- help bacteria adapt to unusual situations eg. antibiotic resistance

28
Q

eukarayotic cell

A

complex cells contain nucleus and membrane bound organelles dna enclosed un nucleus eg. plant animal fungi protists can be single or multi cellular organisms eg. amoeba is uni and eukarayotic
