Identify the features common to all cells. Select all that apply. A. Cell membrane B. Nucleus C. Ribosomes D. Cytoplasm E. Cell wall F. DNA.

All cells share some fundamental features that make them the basic units of life. Every cell is surrounded by a cell membrane (A) that controls what enters and exits the cell. In addition, ribosomes (C) are present in all cells, responsible for protein synthesis, and cytoplasm (D) is the jelly-like substance where these processes occur. Lastly, all cells contain DNA (F), the genetic material that carries instructions for life. While a nucleus (B) is present in eukaryotic cells, it is absent in prokaryotic cells like bacteria. Likewise, a cell wall (E) is found in plant cells and certain prokaryotes but not in animal cells. So, the key common features are A, C, D, and F!
