In a bacterial cell, plasma membrane with all things present within it is called:

Explanation

The correct answer is 'Protoplasm'. In the context of bacteria, the protoplasm is the term used to describe all the living contents within the plasma membrane, which includes both the cytoplasm and the genetic material. The 'Cytoplasmic matrix' refers only to the fluid part of the cytoplasm, excluding organelles and other inclusions. 'Cytoplasm' typically refers to the contents within the cell membrane excluding the nucleus, which is not wholly applicable to prokaryotes as they lack a defined nucleus. 'Cell Structure' is a non-specific term that does not precisely address the composition within the plasma membrane.
