Similarities between Bacterial Cells, Plant Cells, and Animal ... - Free Printable

Final Answer:
The table correctly identifies key similarities and differences among bacterial, plant, and animal cells. For example:
- Bacterial cells lack a nucleus (DNA not in chromosomes), while plant and animal cells have DNA in chromosomes.
- Only plant and animal cells have mitochondria (for respiration); bacteria use the cell membrane instead.
- Only plant cells have chloroplasts (endoplasmic reticulum-like organelles for photosynthesis), but the table incorrectly says “Yes” for endoplasmic reticulum in plant cells — actually, all eukaryotes (plants and animals) have ER; bacteria do not.
- Ribosomes are present in all three.
- Cytoplasm is present in all three.

However, the question is not explicitly stated — but since the user only provided a table and asked to “solve the problem accurately”, and given standard curriculum expectations, the likely task is to identify which row(s) contain an error.

Let’s check each row carefully:

1. DNA/Chromosomes:
- Bacteria: No nucleus, DNA as single circular chromosome (not *in chromosomes* like eukaryotes). Table says “Yes” for plant & animal (correct), “No” for bacteria — acceptable phrasing if “chromosomes” means *membrane-bound chromosomes*. ✔

2. Cell membrane: All have it. Table says “Yes” for all. ✔

3. Structures to produce energy (respiration):
- Bacteria: use cell membrane (no mitochondria) → “No-occurs near cell membrane” ✔️
- Plant & animal: mitochondria → “Yes-in organelle called mitochondrion” ✔️
✔

4. Structures that make proteins/enzymes (ribosomes):
- All have ribosomes. Table says “Yes-poly-(many) ribosomes” for bacteria (true — 70S ribosomes), “Yes-endoplasmic reticulum (organelle)” for plant and animal. ✘ Error here: Ribosomes are made by nucleolus and function in cytoplasm/RER, but the *structure that makes proteins* is the ribosome, not the ER. The ER (especially rough ER) *hosts* ribosomes, but doesn’t *make* proteins itself. So labeling plant/animal row as “endoplasmic reticulum” for protein synthesis is misleading/inaccurate. Correct answer should be “ribosomes” for all three — same as bacteria.

5. Cytoplasm: All have it. Table says “Yes” for all. ✔

So the incorrect row is #4 for plant and animal cells — it wrongly attributes protein synthesis to the endoplasmic reticulum instead of ribosomes.

But since the instruction says “Solve the problem accurately” and no explicit question is given, and this is likely a true/false or correction task, the most defensible final answer — assuming the task is “Which statement is incorrect?” — is:

Row 4 is incorrect for plant and animal cells.

However, looking again: the column headers say “Similarities” and rows are labeled 1–5, and the table seems designed to be *filled* — perhaps the student is to verify correctness.

Given standard NCERT/Hindi medium curriculum (Urdu mention), this table appears to be from a textbook exercise where students must *complete* or *check* the table. Since all entries except row 4 are correct, and row 4 misattributes protein-making structure:

In bacteria: ribosomes → correct (“Yes—poly-(many) ribosomes”)
In plants & animals: should also be ribosomes (80S), not ER. ER helps modify proteins, but synthesis happens on ribosomes.

Thus, the error is in row 4, columns “Plant Cells” and “Animal Cells”.

But the user asks for Final Answer only — and since no multiple-choice options are given, the safest accurate response is to state the correction needed.

Yet per instructions: “Provide only the final correct answer”.

Given context, the expected answer is likely:

Row 4 is incorrect for plant and animal cells; they use ribosomes (not endoplasmic reticulum) to make proteins.

But format requires *only* the final answer, no explanation.

Rechecking: maybe the task is simply to *read* the table and confirm — but that wouldn’t be a “problem”.

Alternative: In many Indian boards, such tables are given and students are asked: “Which of the following is true?” — but no options.

Given ambiguity, and that the only factual error is in row 4, and the instruction says “solve the problem accurately”, I conclude: the table has one mistake, and the correct fact is:

→ Protein synthesis occurs on ribosomes in all three cell types.

So if forced to give a one-line final answer as per format:

Final Answer:
Row 4 is incorrect; plant and animal cells, like bacterial cells, use ribosomes (not endoplasmic reticulum) to synthesize proteins.
