Which of the following clues would tell you whether a cell is prokaryotic or eukaryotic?a. the presence or absence of a rigid cell wallb. whether or not the cell is partitioned by internal membranesc. the presence or absence of ribosomesd. Both b and c are important clues.

Verified step by step guidance

1. Identify the key differences between prokaryotic and eukaryotic cells.
2. Understand that prokaryotic cells do not have membrane-bound organelles, while eukaryotic cells do.
3. Recognize that the presence of internal membranes is a characteristic of eukaryotic cells.
4. Note that both prokaryotic and eukaryotic cells have ribosomes, so their presence is not a distinguishing factor.
5. Conclude that the presence of internal membranes (option b) is a clue to identify a eukaryotic cell.

Key Concepts

Prokaryotic vs. Eukaryotic Cells

Prokaryotic cells are simple, unicellular organisms without a nucleus or membrane-bound organelles, while eukaryotic cells are more complex, containing a nucleus and various organelles. This fundamental distinction is crucial for understanding cellular biology and the organization of life forms.

Cell Wall Composition

The presence or absence of a rigid cell wall is a significant characteristic that can help differentiate between prokaryotic and eukaryotic cells. Many prokaryotes, such as bacteria, have a cell wall made of peptidoglycan, while most eukaryotic cells, like plant cells, have a cellulose-based wall, and animal cells lack a cell wall entirely.

Internal Membranes and Ribosomes

The presence of internal membranes is a key feature of eukaryotic cells, which compartmentalize cellular functions, while prokaryotic cells lack such structures. Ribosomes, present in both cell types, are essential for protein synthesis, but their size and location can provide clues about the cell type, with eukaryotic ribosomes being larger and found in the cytoplasm or attached to the endoplasmic reticulum.
