Question

record the letter of an option in each box in the table to show whether the characteristic describes a eukaryotic cell, a prokaryotic cell, or both types of cell. the options may be used once, more than once, or not at all.

1. prokaryotic
2. eukaryotic
3. both

Explanation:

• Has ribosomes: Both prokaryotic and eukaryotic cells have ribosomes as they are essential for protein synthesis.
• Has a cell membrane: Both prokaryotic and eukaryotic cells are surrounded by a cell membrane that controls the movement of substances in and out of the cell.
• Has DNA in the cytoplasm: Prokaryotic cells have their DNA in the cytoplasm (nucleoid region) as they lack a membrane - bound nucleus.
• Has membrane - bound organelles: Eukaryotic cells have membrane - bound organelles like mitochondria, endoplasmic reticulum etc., which prokaryotic cells lack.

Answer:

• has ribosomes: 3. both
• has a cell membrane: 3. both
• has DNA in the cytoplasm: 1. prokaryotic
• has membrane - bound organelles: 2. eukaryotic
