Final answer:
The organism that has a cell wall among the options provided is fungi (C). Fungal cell walls are composed of chitin and other polysaccharides, providing structural support and protection.
Step-by-step explanation:
The student's question relates to which organisms have a cell wall. Not all cells have cell walls; this feature is more commonly associated with certain eukaryotic cells and prokaryotic cells. In terms of the options provided:
- Animal cells (A) do not have a cell wall.
- L forms (B) are bacteria that can sometimes lose their cell wall but typically have one.
- Fungi (C) have cell walls made of chitin and other polysaccharides.
- Mycoplasmas (D) are a group of bacteria that characteristically do not have a cell wall.
- Protoplasts (E) are plant, fungal, or bacterial cells that had their cell wall removed.
Based on this information, the organism that has a cell wall is the fungi (C). Fungal cell walls provide structural stability and protection, featuring complex polysaccharides such as chitin. This is different from animal cells, which do not have a cell wall and instead have a flexible cell membrane to protect and enclose the cell's internal components.
