Plant cell walls are composed of cellulose, while fungal cell walls are composed of chitin. a group of scientists hypothesize that this difference means the cell wall has largely different functions in plant cells and fungal cells. alternatively, another group of scientists hypothesize that despite their biochemical differences, plant and fungal cell walls serve similar functions.
which of the following observations would best support the alternative hypothesis described above?
a. plant cell walls are found just outside the plasma membrane, while fungal cell walls are found just beneath the plasma membrane.
b. in both plant cells and fungal cells, the cell wall surrounds the outside of the cell membrane.
c. some plant cells have secondary cell walls that confer additional rigidity, while fungal cells do not.
d. photosynthesis occurs in plant cells, but it does not occur in fungal cells.

Explain the cellular functions that occur when antibiotics attack a bacteria cell. a. antibiotics target the cell wall, cell membrane, and the processes of protein and nucleic acids production in bacteria to rupture the cell. b. antibiotics create dormant resistant endospores to preserve the genetic material and rupture the cell. c. antibiotics target the cell wall and form a bridge-like connection to form conjugation. d. antibiotics use binary fission to grow twice its size, replications its dna, and split into two cells.
