In many groups of fungi, karyogamy and plasmogamy are separated in time and space. One potential advantage of this arrangement is that:

A. the mycelium can grow more rapidly.
B. a diploid nucleus can form immediately.
C. mating and spore production can occur in different environments.
D. spores can be produced by meiosis instead of mitosis.
E. the fungus can easily switch between sexual and asexual reproduction.

Advantages of separated karyogamy and plasmogamy.

Explanation:

In many fungi, the time of nuclear fusion is separated from the time of cytoplasmic fusion . This arrangement benefits by allowing mating and spore formation to occur in different environment.

Karyogamy is the process of fusion of nuclei , this precedes spore formation.

Plasmogamy is the fusion of cytoplasm, this process involves mating.

Mating is succeeded by spore formation. Both the processes are favored by different environmental condition.

Explanation:

I could be very wrong, but I hope this helps.

Explanation:

They usually include bacteria and lichens (see Figure below). Along with wind and water, the pioneer species help weather the rock and form soil. Once soil begins to form, plants can move in. The first plants are usually grasses and other small plants that can grow in thin, poor soil.
