Question

which structures are found in each cell type? complete the table. prokaryotic cells eukaryotic cells dna ribosomes mitochondria nucleus

Explanation:

• DNA: Both prokaryotic and eukaryotic cells have DNA. In prokaryotes, it is usually in a circular form in the nucleoid region, while in eukaryotes, it is linear and enclosed within the nucleus.
• Ribosomes: Both cell types have ribosomes as they are essential for protein synthesis.
• Mitochondria: Only eukaryotic cells have mitochondria. These are the power - houses of the cell, generating ATP through cellular respiration. Prokaryotes do not have membrane - bound organelles like mitochondria.
• Nucleus: Only eukaryotic cells have a nucleus. The nucleus houses the DNA in a membrane - bound structure. Prokaryotes lack a true nucleus; their DNA is in the nucleoid region.
