Final answer:
Cytoplasm is a feature common to all cells, regardless of being prokaryotic or eukaryotic. It is the internal environment where metabolic processes take place. The correct answer is C.
Step-by-step explanation:
The features that are common to all cells, both prokaryotic cells and eukaryotic cells, include the following:
- Cytoplasm: A jelly-like substance that fills the inside of the cell, where many of the cell's metabolic processes occur.
- Plasma membrane: An outer covering that separates the cell's interior from its external environment, controlling the movement of substances in and out of the cell.
- Ribosomes: Organelles that are involved in synthesizing proteins within the cell. They can be found either floating freely in the cytoplasm or attached to the endoplasmic reticulum.
- DNA: The genetic material that contains the instructions necessary for the functioning of the cell.
Therefore, of the options provided, C. Cytoplasm is a feature common to all cells. Conversely, A. Nucleus is specific to eukaryotic cells, B. Cell Wall is present in most prokaryotes and some eukaryotes (like plants and fungi), but not all. D. Mitochondria are found only in eukaryotic cells. To address the features shared by all cells, we note that they all have a plasma membrane, cytoplasm, ribosomes, and DNA.
