thinner
thicker
stronger
more rigid

Explanation:

Gram - negative bacteria have a cell wall structure where the peptidoglycan layer is much thinner compared to Gram - positive bacteria. Gram - positive bacteria have a thick peptidoglycan layer, while Gram - negative bacteria have a thin peptidoglycan layer between the outer membrane and the cell membrane. The options "thicker", "stronger", and "more rigid" are characteristics more associated with the peptidoglycan layer of Gram - positive bacteria.
