Question

what structures are present in all cells?
cell membrane, ribosomes, cytoplasm, dna
cell wall, cell membrane, cytoplasm, ribosomes
cell membrane, lysosomes, cytoplasm, dna
cell wall, ribosomes, cytoplasm, dna

Explanation:

All cells, whether prokaryotic (like bacteria) or eukaryotic (like plant and animal cells), have a cell membrane that controls what enters and exits the cell. Ribosomes are involved in protein synthesis. Cytoplasm is the gel - like substance within the cell where many cellular processes occur. DNA is the genetic material that contains the instructions for the cell's functions. Cell walls are not present in animal cells. Lysosomes are mainly found in animal cells and are not universal to all cell types.

Answer:

Cell membrane, ribosomes, cytoplasm, DNA
