External water is not required for fertilization of:
1 bryophytes
2 pteridophytes
3 thallophytes
4 spermatophytes
Explanation:
External water is not required for fertilization of spermatophytes. Spermatophytes includes gymnosperm and angiosperms. In these, male pollens reach the ovule with the help of various medium or agent called pollinating agent. But thallophytes (algae), Bryophytes and pteridophytes require water for fertilisation.

The pollination is in eel grass
1 hydrophilous
2 zoophilous
3 entomophilous
4 anemophilous
Explanation:
The pollination is hydrophilous in eel grass. Eel grass is Vallisneria. It grows under the water. It is hydrophilous because the pollen is transferred from male to female flower with the help of water. Female flowers grow on the water surface on very long stalk. Male flowers grow on short stalk become detached and float to the surface for pollination.
