Bill Nye Cells - ESL worksheet by gmelero - Free Printable

Here is the completed Bill Nye – Cells video worksheet with correct answers based on standard biology content and typical Bill Nye episodes. The answers are matched to the word bank provided.

✔ Questions Section:

1. F. cells
→ *All plants and animals are made of cells.* (Basic cell theory)

2. A. we are made of animal cells
→ *Humans are more like animals such as rabbits than plants because we are made of animal cells.*

3. R. 100 trillion
→ *Humans are made of 100 trillion cells.* (Approximate number in adult human body)

4. M. jobs
→ *Organisms like rabbits have many different kinds of cells to do different jobs.*

5. P. like, different, alive
→ *Cells are like bricks because they are piled up to make something, but they are different because cells are alive and bricks are not.*

6. I. growth
→ *Growth is when more cells are made than die.*

✔ Alive or Not? (Write A for Alive, N for Not Alive)

*(Note: This section doesn’t use the word bank — it’s a separate thinking exercise.)*

Part 1
- N family → Family is a social group, not a living organism.
- N sponge cake → Baked good, not alive.
- N volcano → Geological feature, not alive.
- A sea sponge → Actually a simple multicellular animal (alive).

Part 2
- A potato → Plant organ; contains living cells.
- N potato chips → Processed food, dead cells.
- N gym socks → Fabric item, not alive.

> 💡 *Note: “Sea sponge” is biologically alive (it’s an animal). “Potato” is alive (plant tissue), while “potato chips” are cooked/dead cells.*

✔ Consider the Following: How is a cell like a room in a house?

7. L. cell wall, cell membrane
→ *A room’s wall is like a cell wall or cell membrane because it surrounds the cell.*

8. H. mitochondria
→ *A table in a room is like a mitochondria because it provides energy.*
*(Actually, mitochondria are the “powerhouse” — better analogy for fireplace. Table might be misleading. But based on word bank and context, this is likely intended.)*

9. T. mitosis
→ *Mitosis is the process of one cell becoming two cells.*

10. K. DNA
→ *DNA are the road map for cells and tell the cells what to do.*

11. S. white blood cells
→ *White blood cells are our body’s fastest growing organ because we shed millions of these cells every day.*
*(Technically, white blood cells are cells, not organs — but this is common simplification in educational videos.)*

12. J. egg
→ *Genes are made of DNA.*
*(Wait — this should be K. DNA. Let’s fix mismatches below.)*

> ⚠️ Correction Needed:
Question 12 says “Genes are made of ______” → Correct answer is K. DNA
Question 13 says “Humans have ______ pairs of chromosomes (46 total)” → G. 23

Let’s reassign correctly:

✔ Revised & Corrected Answers for “Consider the Following”:

7. L. cell wall, cell membrane
8. H. mitochondria *(Fireplace = energy → mitochondria)*
9. T. mitosis
10. K. DNA
11. S. white blood cells
12. K. DNA *(Genes are made of DNA)*
13. G. 23 *(Humans have 23 pairs = 46 total chromosomes)*
14. O. genes *(Name one large single cell that is very easy to see → J. egg — human egg cell is visible to naked eye)*

> ❗ Question 14: “Name one large single cell that is very easy to see” → J. egg

15. E. iron, oxygen
→ *Red blood cells are red because the iron in the cell mixes with the oxygen we breathe in.*

16. S. white blood cells
→ *White blood cells attack viruses to keep us from getting sick.*

17. C. osmosis
→ *Osmosis is how cells exchange chemicals with the environment and other cells.*
*(Note: Osmosis is specifically water movement; diffusion is general chemical exchange. But in Bill Nye’s simplified terms, osmosis is often used broadly.)*

18. N. nerve cell
→ *The only type of human cell that is never replaced is nerve cell.*
*(Neurons in CNS generally don’t regenerate.)*

19. D. alive
→ *One of the characteristics of being alive is being made of cells.*

✍️ Write a GIST for this video:

> GIST: All living things — plants and animals — are made of cells. Cells are like tiny building blocks that do different jobs. Humans have about 100 trillion cells. Cells are alive — unlike bricks — and can grow, divide (mitosis), and respond to their environment. Different parts of the cell have special functions: the nucleus holds DNA (the cell’s instructions), mitochondria make energy, and the cell membrane controls what enters and leaves. Some cells, like nerve cells, last a lifetime, while others, like skin or white blood cells, are constantly replaced. Being made of cells is one key characteristic of life.
