Step-by-step solution for: Amoeba Sisters Video Recap Worksheet
Let’s go through each question one by one, step by step.
---
Question 1: Are viruses considered to be living organisms? Why or why not?
Viruses are NOT considered living organisms. Here’s why:
- Living things can reproduce on their own — but viruses cannot. They need to infect a host cell (like a human or animal cell) to make copies of themselves.
- Living things grow and develop — viruses don’t grow. They just assemble inside host cells.
- Living things use energy — viruses don’t eat or use energy like cells do.
- So, because they can’t do these basic life things without help from a host, scientists say they’re not alive.
✔ Final Answer for Q1: No, viruses are not considered to be living organisms. They cannot reproduce on their own.
---
Question 2: Are viruses considered to be cells? Would they be included in these cell theory statements?
Cell Theory says:
1. All living things are made of cells.
2. Cells come from other cells.
3. The cell is the smallest unit of life.
Viruses are NOT cells. They don’t have cell parts like membranes, organelles, or cytoplasm. They’re just genetic material (DNA or RNA) wrapped in protein.
So, since viruses aren’t cells and aren’t even considered alive, they DON’T fit into Cell Theory at all.
✔ Final Answer for Q2: No. Viruses are not cells. The cell theory statements do not apply to viruses as viruses are not cells.
---
Question 3: Compare and contrast a virus to a cell. What would be some differences? What are some similarities?
Let’s break it down:
Differences:
- Size: Viruses are MUCH smaller than cells.
- Structure: Cells have many parts (nucleus, mitochondria, etc.). Viruses are simple — just genetic material + protein coat.
- Reproduction: Cells divide on their own. Viruses need to hijack a host cell to copy themselves.
- Life status: Cells are alive. Viruses are not considered alive.
Similarities:
- Both have genetic material (DNA or RNA).
- Both can cause disease (some viruses and some bacteria/cells can make you sick).
✔ Final Answer for Q3: Viruses are much smaller than cells. Viruses have genetic material (DNA or RNA), and cells also have genetic material. But viruses can’t live or reproduce without a host, while cells can.

Now let’s look at the bottom part — the “True/False” questions with explanations.
We’ll go one by one:
---
Bottom Left Box:
1. _T_ Viruses can be treated with antibiotics.
Wait — this is FALSE! Antibiotics only work on BACTERIA, not viruses. If you have a viral infection (like flu or cold), antibiotics won’t help. Doctors might give antiviral meds instead.
✘ Correction: This should be F, not T.
Explanation: Antibiotics kill bacteria. Viruses are different — they need antivirals, not antibiotics.
---
2. _F_ Viruses are smaller than the hosts they infect.
Actually, this is TRUE! Viruses are tiny — way smaller than the cells they infect. For example, a flu virus is super small compared to your lung cells.
✔ So this should be T, not F.
Explanation: Yes, viruses are always smaller than the host cells they invade.
---
3. _T_ Viruses are prokaryotes.
NOPE — false again! Prokaryotes are types of CELLS (like bacteria). Viruses aren’t cells at all — so they can’t be prokaryotes OR eukaryotes.
✘ Should be F
Explanation: Prokaryotes are single-celled organisms without a nucleus. Viruses aren’t cells — so they don’t fit into that category.
---
4. _F_ Since viruses are not cells, therefore, they are not pathogens or harmful.
This is WRONG logic. Just because something isn’t a cell doesn’t mean it can’t hurt you. Many viruses ARE pathogens — like HIV, Ebola, flu, coronavirus — they cause serious diseases.
✘ Should be F — but the reason given is wrong. Actually, viruses CAN be harmful even though they’re not cells.
Explanation: Being non-cellular doesn’t mean harmless. Viruses are major causes of disease worldwide.
---
Bottom Right Box:
1. _T_ Some structures include biomolecules such as proteins and nucleic acids.
YES — true! Viruses are made of proteins (the outer shell) and nucleic acids (DNA or RNA inside). Even cells have those too.
✔ Correct as T
Explanation: All viruses have protein coats and genetic material — which are biomolecules.
---
2. _T_ Viruses require a host to reproduce.
ABSOLUTELY TRUE. That’s one of the biggest reasons they’re not considered alive — they can’t replicate alone.
✔ Correct as T
Explanation: Without a host cell, a virus is just sitting there — inactive. It needs the host’s machinery to make more viruses.
---
3. _F_ Viruses only target animals including humans.
FALSE! Viruses infect ALL kinds of living things — plants, fungi, bacteria (those are called bacteriophages!), and yes, animals too.
✘ Should be F — correct label, but let’s explain why.
Explanation: There are plant viruses (like tobacco mosaic virus), bacterial viruses, fungal viruses — not just animal ones.
---
4. _F_ Viruses are larger than bacteria.
NOPE — actually, viruses are usually SMALLER than bacteria. Bacteria are whole cells; viruses are tiny particles.
✘ Should be F — correct label.
Explanation: Most bacteria are visible under a regular microscope. You need an electron microscope to see most viruses — they’re that small.
---
Now let’s compile all corrected answers clearly.

Final Answers:
Top Section:
1. No, viruses are not considered to be living organisms. They cannot reproduce on their own.
2. No. Viruses are not cells. The cell theory statements do not apply to viruses as viruses are not cells.
3. Viruses are much smaller than cells. Viruses have genetic material (DNA or RNA), and cells also have genetic material.
Bottom Section (Corrected True/False):
Left Side:
1. F — Viruses cannot be treated with antibiotics. Antibiotics only work on bacteria.
2. T — Viruses are smaller than the hosts they infect.
3. F — Viruses are not prokaryotes. Prokaryotes are cells; viruses are not cells.
4. F — Viruses can still be harmful/pathogens even though they are not cells.
Right Side:
1. T — Some structures (including viruses) include biomolecules such as proteins and nucleic acids.
2. T — Viruses require a host to reproduce.
3. F — Viruses do not only target animals — they can infect plants, bacteria, fungi, etc.
4. F — Viruses are generally smaller than bacteria.
