BIOXII02: SEXUAL REPRODUCTION IN FLOWERING PLANTS

341683 In monoecious plants having unisexual flowers means

341684 Statement A :
Some examples of water pollinated plants are
Vallisneria
and
Hydrilla
which grow in marine water and several fresh water species such as
Zostera
.
Statement B :
The synergids have special cellular thickenings at the chalazal tip called filiform apparatus, which play an important role in guiding the pollen tubes into the synergid

2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
