f. sites of protein synthesis
g. is composed of lipids and proteins, and serves as a selective barrier h. is composed of lipid A, which is an endotoxin
i. maintains cell shape
j. external protein structures for adherence

Answer 1

a)cell wall : maintain cell shape

b) capsule: Polysaccharides attached to cell wall that resist phagocytosis

c) flagella : filamentous appendages for movement

d)plasma membrane : it is composed of lipid and protein serves as selective barrier

e) ribosomes : site of protein synthesis

f) fimbrae : external protein structure for adherence

g) LPS : it is composed of lipid A , which is endotoxin

h) inclusion bodies : energy reserve in cell

I) nucleoid : contain cells DNA

j) cytoplasm : substance inside the cell that contains enzymes and cell structure
