Question

175. Assertion : Presence of pneumatophores is a
special adaptation of hydrophytes.
Reason: Pneumatophores are positively
geotropic shoots that have lenticels and help
in gaseous exchange.​

Answer 1

Answer:

Both assertion and reason are false.

Explanation:

Presence of pneumatophores is a special adaptation of halophytes

Halophytes live mostly in saline and brackish waters but completely submerged or partially submerged.

Due to these conditions they develop a special adaptation like pneumatophores.

And pneumatophores are negatively geographic.

pneumatophores-They bear breathing pores (lenticels) and emerge out of the soil for gaseous exchange. Hence, they are negatively geotropic.
