Which of these has a cell wall composed of cellulose
Asked by admin @ in Biology viewed by 232 People
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.
