Question

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

Explanation:

• Ribosomes: Both prokaryotic and eukaryotic cells need to synthesize proteins. Ribosomes are the sites of protein synthesis, so they are present in both cell types.
• Nucleus: Prokaryotic cells lack a membrane - bound nucleus. Their DNA is in the nucleoid region. Eukaryotic cells have a true, membrane - bound nucleus.
• Rough endoplasmic reticulum (RER): RER is associated with ribosomes and is involved in protein synthesis and modification. Prokaryotic cells lack membrane - bound organelles like the RER. Eukaryotic cells have the RER.
• DNA: Both prokaryotic and eukaryotic cells contain DNA. In prokaryotes, it is usually a single, circular chromosome in the nucleoid. In eukaryotes, DNA is organized into multiple linear chromosomes within the nucleus (and also in mitochondria and chloroplasts in some eukaryotes).

Answer:

	Prokaryotic cells	Eukaryotic cells
Nucleus	❌	✔️
