Plants which produce characteristic pneumatophores and show vivipary belong to:
Options
- AMesophytes
- BHalophytes
- CPsammophytes
- DHydrophytes
Correct answer
B. Halophytes
Step-by-step solution
This is a salt-tolerant plant group that grows in soil or waters of high salinity, coming into contact with saline water through its roots or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs and seashores.
Halophytes growing in saline soils or near the delta of a river, show:
- Vivipary which is in-situ seed germination. The seeds, while remaining attached in the mother plant, germinate and then shaded off.
- Pneumatophores or the breathing roots are for gaseous exchange.
