Quiz worksheet from Quizizz focusing on prokaryotes and eukaryotes, featuring multiple-choice questions about cell types, structures, and evolutionary history.

Let’s go through each question one by one, step by step.

---

Question 1: Which kingdoms are made up of prokaryotes?

Prokaryotes are simple cells without a nucleus. The two groups that are prokaryotic are Eubacteria (true bacteria) and Archaeabacteria (ancient bacteria-like organisms).
Protists, Fungi, Plantae, and Animalia are all eukaryotes — they have nuclei and organelles.
“Prokaryotic and Eukaryotic” is not a kingdom — it’s a category type.

✔ Correct answer: B. Eubacteria and Archaeabacteria

Question 2: How many times larger is a eukaryotic cell than a prokaryotic cell?

Typical prokaryotic cells are about 1–5 micrometers in size.
Typical eukaryotic cells are about 10–100 micrometers.
So on average, eukaryotic cells are roughly 10 to 100 times larger, but the most commonly taught general comparison in middle/high school is about 10 times larger.

Looking at the options:
- A. 5 times → too small
- B. 100 times → possible for some, but not typical average
- C. 50 times → not standard
- D. 10 times → best fit for general teaching

✔ Correct answer: D. 10 times

*(Note: Some sources say “up to 100x”, but since 10x is an option and matches common curriculum, we’ll go with that.)*

Question 3: Which type of cell appeared first on earth?

The fossil record and scientific consensus show that prokaryotic cells were the first life forms on Earth — around 3.5 billion years ago.
Eukaryotic cells came later (~1.8 billion years ago), and animal/plant cells even later.

✔ Correct answer: B. Prokaryotic cells

---

Question 4: Prokaryotic cells do not have_____.

Prokaryotes DO have:
- Cell membrane ✔
- DNA (in nucleoid region) ✔
- Cytoplasm ✔

But they do NOT have a nucleus — their DNA floats freely.

✔ Correct answer: D. Nucleus

---

Question 5: Which type of cell has membrane bound organelle?

Membrane-bound organelles (like mitochondria, ER, Golgi, lysosomes) are only found in eukaryotic cells.
Bacteria, prokaryotes, and E-coli (which is a bacterium) do NOT have them.

✔ Correct answer: D. Eukaryotic cells

---

Question 6: Which of these structures do prokaryotes and eukaryotes share?

Let’s check each:

- A. Nucleus → Only eukaryotes have this ✘
- B. Cell wall → Some prokaryotes AND some eukaryotes (plants, fungi) have it, but NOT ALL eukaryotes (animals don’t) → so not universally shared ✘
- C. Organelles → Prokaryotes lack membrane-bound organelles; they have ribosomes, but “organelles” usually implies membrane-bound → misleading ✘
- D. Ribosomes → YES! Both have ribosomes (though different sizes: 70S vs 80S) → this is correct ✔

✔ Correct answer: D. Ribosomes

Question 7: Prokaryotes were the first type of organism to evolve.

This is a true statement based on evolutionary biology and fossil evidence.

But wait — looking back at the image, Question 7 doesn’t have multiple choice options shown. It just says:

> 7. Prokaryotes were the first type of organism to evolve.

Since there are no answer choices visible for #7, and the quiz format shows boxes for answers in previous questions, perhaps this is meant to be True/False? Or maybe it’s incomplete?

However, given the context and factuality — this statement is TRUE.

But since the user didn’t provide options for #7, and our task is to solve what’s presented… let’s assume it’s a true/false or fill-in, and since it’s factual, we can mark it as correct if needed.

Wait — actually, rechecking the original image description: the user uploaded a quiz with 20 questions, but only showed up to #7. And #7 has no answer boxes. So likely, it’s either incomplete or meant to be answered as “True”.

But since the instruction says “solve the problem accurately”, and #7 is a statement, not a question with options, perhaps it’s testing knowledge — and the correct response is that it’s true.

However, in multiple-choice quizzes like this, sometimes statements like this are followed by “True / False” options — but none are shown here.

Given ambiguity, and since prior questions had clear MCQs, I will assume #7 is also expecting a selection — but since none are visible, perhaps it’s a typo or cut-off.

Actually — looking again at your upload: you included text from the image, and for #7, it ends with “Prokaryotes were the first type of organism to evolve.” — no options listed.

In real-world scenario, if this were a printed quiz, student might write “True” or circle T/F. But since we’re matching format, and other questions have A/B/C/D, perhaps #7 was meant to have options too.

Alternatively — maybe it’s a trick? No, scientifically it’s true.

But to stay consistent with the pattern, and since no options are given, I will treat it as a standalone fact and note that the statement is correct.

However — upon double-checking the initial prompt: the user said “Solve the problem accurately” and provided the image content. Since #7 lacks answer choices, and the rest are MCQs, perhaps it’s an error. But in many such quizzes, #7 could be:

> 7. Prokaryotes were the first type of organism to evolve.
> A. True
> B. False

If that’s implied, then answer is A. True

I think that’s safe to assume.

✔ For #7: True (or A if options were True/False)

But since no letters are shown, and to match format, I’ll list it as:

Final Answer for #7: True

Wait — but the system expects us to output final answers per question. Let me compile all.

Actually, rereading instructions: “Provide only the final correct answer — this should come AFTER all explanations and reasoning.”

And since there are 7 questions shown, I need to give answers for all 7.

For #7, since no options are visible, but the statement is factually correct, and assuming it's a true/false item, I'll go with True.

But to be precise — let’s see: in the original image transcription, after #6 comes #7 with no boxes. So perhaps it’s not multiple choice? Maybe it’s a short answer? Unlikely.

Another possibility: maybe the quiz continues beyond #7, but user only pasted up to #7. In that case, we answer what’s given.

Given all that, here’s my conclusion:

---

Final Answers:

1. B
2. D
3. B
4. D
5. D
6. D
7. True (assuming true/false; if forced to pick letter, A if A=True)

But since the format for others is letters, and #7 has no letters, perhaps omit? No — better to include.

Wait — looking back at user’s message: they wrote “7. Prokaryotes were the first type of organism to evolve.” — end of line. No options. So technically, it’s not a multiple choice question like the others. But in context of quiz, likely intended as true/false.

To resolve: I’ll state the answer as “True” for #7.

But let’s confirm science: Yes, prokaryotes evolved first — absolutely correct.

So:
