Biology worksheet featuring a blank Venn diagram for students to categorize cell organelles like chloroplasts and cell walls.

To complete this Venn diagram, we need to sort the list of words into three categories: things found only in plant cells, things found only in animal cells, and things found in both.

Here is the step-by-step sorting process:

1. Cell membrane: All cells (plant and animal) have a cell membrane to hold them together. -> Both
2. Nucleus: Both plant and animal cells are eukaryotic, meaning they both have a nucleus. -> Both
3. Ribosome: Ribosomes make proteins and are found in all cells. -> Both
4. Large vacuole: Plants typically have one large central vacuole for water storage. Animals usually don't. -> Plant
5. Mitochondria: Both plants and animals need energy, so they both have mitochondria. -> Both
6. Chloroplast: This is where photosynthesis happens. Only plants do this. -> Plant
7. Cytoplasm: The jelly-like substance inside cells is found in both. -> Both
8. Cell wall: Plants have rigid walls for support; animals do not. -> Plant
9. Small vacuole or none: Animal cells might have tiny vacuoles, but not the big ones plants have. -> Animal
10. Rectangular shape: Plant cells are often boxy or rectangular because of their cell walls. -> Plant
11. Round or irregular shape: Animal cells are softer and rounder. -> Animal

Now we can fill in the sections:

* Plant Only: Cell wall, Chloroplast, Large vacuole, Rectangular
* Animal Only: Small vacuole or none, Round or irregular shape
* Both: Cell membrane, Nucleus, Ribosome, Mitochondria, Cytoplasm

Final Answer:
Plant Circle: Cell wall, chloroplast, large vacuole, rectangular
Animal Circle: Small vacuole or none, round or irregular shape
Middle (Both): Cell membrane, nucleus, ribosome, mitochondria, cytoplasm
