| 1. | Sporangia are borne in the axil or on the adaxial surface of the sporophyll.
|
| 2. | The sepals have bristles on the adaxial surface.
|
| 3. | Dark green on the adaxial side, while abaxially they tend to be much paler.
|
| 4. | At the same time, condensation occurs in thin film on the adaxial face of the spore.
|
| 5. | Pupation takes place in a cocoon, usually made on the adaxial leaf surface of adjacent leaves.
|
| 6. | There are also four interradial tentacles that are small and solid . these have adaxial nematocyst clusters.
|
| 7. | The xylem typically lies on the adaxial side of the vascular bundle and the phloem typically lies on the abaxial side.
|
| 8. | They mine the adaxial ( toward the center ) epidermis of the leaf, forming a narrow, long serpentine mine.
|
| 9. | Lycophytes, in contrast, bear their sporangia on the adaxial surface ( the upper side ) of leaves or laterally on stems.
|
| 10. | The adaxial and abaxial surface of the leaf is covered with yellowish or purplish spines that grow from purple wart-like structures.
