Plant cell shows distinguishing features from the animal cell which can be easily observed like:
1. Shape: Plant cell is usually rectangular while the animal cell is circular.
2. Membrane : Plant cell posses two layers- outer cell wall and inner plasma membrane while the animal cell only plasma membrane.
3. Vacuole: plant cell contains a single large vacuole whereas animal cell contains small vacuole if any.
4. Ribosomes: plant cell posses more free cytoplasmic ribosomes while animal cell contains more attached ribosomes.
On the basis of this, we can predict that James is preparing a plant cell with balloon shoeing large vacuole and marbles as ribosomes.
Thus, option B is the correct answer.
The option that describes a benefit of sustainable agriculture is ; ( D ) soil erosion is reduced
