Body Structure: Eubacteria are single-celled organisms with a cell wall outside of the cell to protect them.
Food: Eubacteria are both auto- and heterotrophic which means they can be either autotrophic, they use both chemical synthesis and photosynthesis.
Animals lack the cell wall, planate are autotrophic and protists are eukaryotic organisms so the correct answer is eubacteria.

Gram-positive and Gram-negative are different in their resistance to antibiotics. It is because of their different structure of cell wall. Gram-positive bacteria have a thick peptidoglycan cell wall and dyes purple in the Gram test (for categorization of bacteria). Gram-negative bacteria have thin peptidoglycan layer and do not turn purple. Gram-positive bacteria are easier to kill because their thick peptidoglycan layer absorbs antibiotics.
