An enzyme breaks down cellulose.
A scientist treated equal-sized samples of two eukaryotic tissues with the enzyme. One sample was plant tissue and the other was animal tissue.
The scientist measured the force needed to compress each tissue sample by the same distance.
| Tissue sample | Force before enzyme treatment in mN | Force after enzyme treatment in mN |
|---|---|---|
| R | 9.6 | 2.4 |
| S | 3.0 | 2.9 |
Explain which sample came from the plant tissue. Use the data in the table.
