Question

. Which of the following has haploid type of nucleus?
(1) Cycas
(2) Salvinia
(3) Funeria
(4) Fucus​

Answer 1

Answer:

Funaria

Explanation:

• Funaria is a Bryophyte with predominant gametophytic stage. Hence, cheifly, it's cells have haploid nucleus.
• Cycas is gymnosperm with diplontic life cycle.
• Salvinia is pteridophyte with Diplo-haplontic life cycle.
• Fucus is a diploid brown algae.

Answer 2

Solution:

Funaria has the haploid type of nucleus.

Explanation:

• Funaria is a moss species belonging to the brypophyte.
• They show alternation of generation means the gametophytic stage is alternated with the sporophytic stage.
• Gametophytic is predominant hence its cell has a haploid nucleus.
• hence option 3 is correct that is funeria.
