Question

which structures are found in each cell type? complete the table. prokaryotic cells eukaryotic cells rough endoplasmic reticulum ribosomes dna nucleus submit

Explanation:

• Rough endoplasmic reticulum: Present in eukaryotic cells (has ribosomes attached, involved in protein synthesis for secretion/insertion into membranes). Prokaryotic cells lack membrane - bound organelles like this.
• Ribosomes: Both prokaryotic and eukaryotic cells have ribosomes. In prokaryotes, they are 70S (smaller), in eukaryotes, 80S (larger, but still a ribosome structure for protein synthesis).
• DNA: Both have DNA. Prokaryotic DNA is usually circular and in the nucleoid region. Eukaryotic DNA is linear and in the nucleus (also some in mitochondria/chloroplasts).
• Nucleus: Membrane - bound nucleus is a feature of eukaryotic cells. Prokaryotic cells have no nucleus (nucleoid instead).
