multiple choices

Item(s) that are typically described as "diploid"

a. bacterial plasmids carrying resistance genes

b.moss sporophytes

c.thermophilic Archaea, living in a hot spring

d.cells in the stalk of a typical mushroom

e.plant and animal zygotes

f.female gametophytes, in most land plants

g.fern leaves

h.pollen

Answer 1

a. bacterial plasmids carrying resistance genes - polyploid...
becuase the number may occurs in large number.

b.moss sporophytes - Diploid.

c.thermophilic Archaea, living in a hot spring - Haploid
Archeaea are haploid because they have only one set of chrmosomes.

d.cells in the stalk of a typical mushroom - Diploid'
As the meiosis occurs in the mushroom cap or mushroom umberealla, the stalk is purely diploid.

e.plant and animal zygotes - Diploid
As the zygotes are the resuls of fusion of haploid gametes, it is diploid.

f.female gametophytes, in most land plants - Haploid
As the female and male gametyophytes are result of meiosis, those are haploid.

g.fern leaves - Diploid
As the fern plant is diploid, the leaves, roots somatic body part are in diploid.

h.pollen - Haploid
As the pollen is result of meiosis, it is haploid.
