Answer: (A)

Verified step by step guidance

1. Understand the question: The problem is asking for the term that describes all material in a tissue that is not cellular. This means we are looking for components outside of the cells themselves.
2. Review the options: The options provided are 'Extracellular matrix,' 'Nucleus,' 'Plasma membrane,' and 'Cytoplasm.' Each term needs to be evaluated based on its definition and relevance to the question.
3. Define the terms: (1) Extracellular matrix refers to the network of proteins, polysaccharides, and other molecules located outside of cells that provide structural and biochemical support to surrounding cells. (2) Nucleus is the organelle within a cell that contains genetic material. (3) Plasma membrane is the lipid bilayer that encloses the cell, separating its interior from the external environment. (4) Cytoplasm is the gel-like substance inside the cell, excluding the nucleus, where organelles are suspended.
4. Eliminate incorrect options: (1) Nucleus, plasma membrane, and cytoplasm are all components of the cell itself, so they do not describe material outside of the cell. (2) The extracellular matrix, however, is specifically located outside of cells and fits the description of non-cellular material in a tissue.
5. Conclude the correct answer: Based on the definitions and elimination process, the term that best describes all material in a tissue that is not cellular is 'Extracellular matrix.'
