| 1. | The mine is serpentine and located in the upper epidermis and mesophyll.
|
| 2. | After overwintering, the larvae begin feeding on the mesophyll in March.
|
| 3. | They then feed on the green tissues or the green mesophyll layer.
|
| 4. | In mesophyll chloroplasts, which do not synthesize sugars, lack starch granules.
|
| 5. | Crystals of calcium oxalate are in the leaf mesophyll.
|
| 6. | Most of the mesophyll cells fold their cell wall in response to desiccation.
|
| 7. | They feed on the mesophyll from the inner side of the rolled leaf.
|
| 8. | Beneath the palisade mesophyll are the spongy mesophyll cells, which also perform photosynthesis.

| 10. | They ate one surface and mesophyll of the leaf, leaving the other epidermis.
