(D)Cycas	(iv)Carpogonium (v)Multiciliated magle gamates

• A. A- (i), B- (iv), C- (iii), D- (v)
• B. A- (iv), B- (i), C- (ii), D- (v)
• C. A- (iv), B- (ii), C- (iii), D- (i)
• D. A- (iv), B- (v), C- (ii), D- (i)

Answer 1

The correct option is B A- (iv), B- (i), C- (ii), D- (v)

The stationary female gametes in Gracilaria are the corpogonium.

Ectocarpus is a genus of filamentous brown algae and reproduce asexually by biflagellate zoospores.

In Marchantia the male gametes are called anterozoids and are biflagellate in structure.

Cycas is a diecious plant that contains both the male and female on one plant. The male gametes are flagellated and ciliated. In this both foramtion of polle tube and the participation of male gamets takes place.

Hence the correct option is B.
