Answer: A fern gametophyte produces eggs and sperm in archegonium portion and antheridium portion respectively
Ferns are bisexual and go under sexual reproduction. Ferns reproduce by using spores. In haploid phase each of the cells contain only one copy of each chromosome and in the multicellular diploid phase where each of the cell contained two copies of each chromosomes.
The sperms are produced in the antheridium portion and the eggs are produced in the archegonium portion
Carrying capacity refers to the population size in which an
environment can sustain, given also the resources within it. A country may have
low carrying capacity if these available resources can no longer support the
population, which can decline the survivability.
