What is the ploidy level of A.) Ceratopteris gametophyte? B.) its Anthareridia and Archegonia? and C.) its gametes?
Solution
Ploidy is the Set of chromosomes present in an organism. If organism contain one set of Chromosomes, then it is called Haploid. If organism contain two sets of Chromosomes, then it is called Diploid etc......
The species Ceratopteris thalictroides is a fern species belonging to the genus Ceratopteris, whose chromosome counts of 2n=156.
A. Ceratopteris gametophyte: Gametophyte is Haploid, Multi Cellular organism that produce Gametes: As it is Haploid, it contain n = 78 chromosomes
B. Antharedia: Haploid Male reproductive structurs similar to Testes in animals. They produce sperms. Archegonia: Haploid Female reproductive structurs similar to ovaries in animals. They produce eggs.
C. Gammetes are Haploids upon fusion, they give Diploid Zygote
