The correct answers are
used to engulf food- pseudopodia
Pseudopodia are the structures found in amoeba and similar organisms that allow them to take in food. The pseudopodia are formed by changes in the shape of the cell. The amoeba posses a highly elastic cell membrane that allows their cell to change shape into pseudopodia that surround the food particle and engulfs it trough endophagocytosis.
incapable of surviving with oxygen- anaerobes
Anaerobes are microbes that are unable to survive in environments that contain oxygen.
Oxygen, although very important for cell processes is highly toxic and can form radicals that can damage various cell structures and even the cell's genetic material-the DNA. The cells that are unable to protect themselves from the effects of oxygen must live in an anaerobic environment, an environment without oxygen.
present in bacterial cell wall-peptidoglycan
Bacterial cells are prokaryotic cells that possess an outer layer of protection, a cell wall that surrounds the cell membrane.
The cell wall is not a unique characteristic of the bacteria since the plants and fungal cells both possess one. Although they have similar roles, their structure is different and the bacterial cell wall is made out of peptidoglycan, lipids, and proteins.
present in fungi cell wall-chitin
Fungal cells are eukaryotic cells that have an outer protective layer. This sets them apart from other heterotrophic organisms in the Eukarya domain (animals for example).
The fungal cell wall is different in structure from the plant and bacterial cell walls and its composed out of various proteins, the most prominent one being chitin.
