You are observing a cell. Its cell wall is not made ofcellulose; rather, it is constructed of a long-chain polysaccharidecalled peptidoglycan. This type of cell has the ability tomake all but the simplest molecules and can make all of the 20amino acids.
a) what kind of cell is it? justify your answer
b)
- If this type of cell contained pigments capable ofphotosynthesis, what would it be called?
