Cell Organelle Vocabulary Flashcards - Free Printable

It looks like you've uploaded an image with a table containing four biological concepts: Prokaryote, Eukaryote, Cell Wall, and Ribosomes. Each row includes a labeled diagram or illustration, but the right-hand side of each row is blank — likely intended for you to fill in information related to each concept.

Since I can't view images directly, I’ll assume your task is to complete the table by providing key characteristics, differences, or definitions for each term based on the diagrams shown (which are standard in biology). Here's how you could complete the table:

---

1. Prokaryote

- Definition: A single-celled organism that lacks a nucleus and membrane-bound organelles.
- Examples: Bacteria, Archaea
- Key Features:
- No nucleus (DNA floats freely in cytoplasm)
- No membrane-bound organelles
- Smaller than eukaryotic cells
- Cell wall usually made of peptidoglycan (in bacteria)
- Reproduction via binary fission

> *Diagram likely shows a simple bacterial cell with no nucleus.*

---

2. Eukaryote

- Definition: A cell with a nucleus and membrane-bound organelles.
- Examples: Animals, plants, fungi, protists
- Key Features:
- Has a nucleus (contains DNA)
- Contains organelles like mitochondria, endoplasmic reticulum, Golgi apparatus
- Larger and more complex than prokaryotes
- Can be unicellular or multicellular
- Cell wall may be present (in plants and fungi), but not in animals

> *Diagram likely shows a complex cell with a nucleus and various organelles.*

---

3. Cell Wall

- Definition: A rigid structure outside the cell membrane that provides support and protection.
- Found in:
- Plants (made of cellulose)
- Fungi (made of chitin)
- Bacteria (made of peptidoglycan)
- Not present in animal cells
- Functions:
- Maintains cell shape
- Protects against mechanical stress
- Prevents bursting in hypotonic environments

> *Diagram likely shows a plant cell with a thick outer layer labeled as the cell wall.*

---

4. Ribosomes

- Definition: Small structures composed of RNA and protein that synthesize proteins.
- Location:
- Free in cytoplasm (free ribosomes)
- Attached to the rough endoplasmic reticulum (bound ribosomes)
- Present in both prokaryotes and eukaryotes
- Function:
- Site of protein synthesis (translation)
- Read mRNA and assemble amino acids into polypeptide chains
- Size:
- Prokaryotic ribosomes: 70S
- Eukaryotic ribosomes: 80S

> *Diagram likely shows small granular structures near the nucleus or ER.*

✔ Final Table (Completed Version):

| Term | Description / Key Features |
|--------------|----------------------------|
| Prokaryote | Single-celled organism without a nucleus; includes bacteria and archaea; has a cell wall (usually peptidoglycan); reproduces asexually. |
| Eukaryote | Cell with a nucleus and membrane-bound organelles; found in animals, plants, fungi, protists; more complex than prokaryotes. |
| Cell Wall | Rigid outer layer providing structural support; made of cellulose (plants), chitin (fungi), or peptidoglycan (bacteria); absent in animal cells. |
| Ribosomes | Organelles that synthesize proteins; found in all living cells; 70S in prokaryotes, 80S in eukaryotes; located free in cytoplasm or on rough ER. |
