Question

a student was given four specimens and was asked to describe each. the student made the table below. according to the information, which specimen is prokaryotic? specimen 1 is prokaryotic because it contains a nucleus. specimen 2 is prokaryotic because it lacks a nucleus. specimen 3 is prokaryotic because it contains chloroplasts. specimen 4 is prokaryotic because it lacks chloroplasts.

Explanation:

Step1: Recall prokaryotic cell features

Prokaryotic cells are single - celled, have circular DNA, and lack a nucleus.

Step2: Analyze each specimen

• Specimen 1: Multicellular, sexual reproduction, has a nucleus (not prokaryotic).
• Specimen 2: Single - celled, asexual reproduction, circular DNA, no nucleus (matches prokaryotic features).
• Specimen 3: Multicellular, sexual reproduction, has a nucleus (not prokaryotic).
• Specimen 4: Multicellular, has a nucleus (not prokaryotic).

Answer:

Specimen 2 is prokaryotic because it lacks a nucleus.
