B) spirilla are found in chains of cells whereas spirochetes exist as individual cells.
Where Are Cell Walls Found. The secondary cell wall is a structure found in many plant cells, located between the primary cell wall and the plasma membrane. Plants, animals, fungi, and algae have cell walls.

A cell wall is a fairly rigid layer surrounding a cell located outside of the plasma membrane that provides additional support and protection. Animals and most other protists have cell membranes without surrounding cell walls. Cell organelle is a specialized entity present inside a particular type of cell that the critical function of the cell wall is protecting and maintaining the shape of the cell.

How do some bacteria fly under the radar of antibiotics and our immune system? From the outermost layer of the cell wall, these layers are identified as the middle lamella. Fungal cell walls are largely made of chitin, which is the same substance in insect exoskeletons. Using biochemical and cell biology experiments, his research group was able to show that pi4p, a membrane building block, plays two roles during cell division:
