Question 1

Answer 1

A zygote is 2n..

Question 2

What is plasmogamy?

Answer 2

Plasmogamy is when

Question 3

What is Karyogamy?

Answer 3

Karyogamy is when

Question 4

What is the heterokaryotic stage?

Answer 4

The heterokaryotic stage is when

Question 5

The process of Karyogamy produces a d______ (2n) z_____

Answer 5

Diploid

Zygote

Question 6

What is a haploid cell?

Answer 6

ONE copy of each chromosome. Non-homologous chromosome. 1n (n).

A cell with a normal amount of genetic information.

Question 7

What’s a diploid cell?

Answer 7

TWO copies of a each chromosome. Pair of homologous chromosomes (2n) (of maternal and paternal origin)

Twice the normal amount of genetic information.

Question 8

In terms of N in sexual reproduction, what happens?

Answer 8

• TWO haploid cells (1n and 1n) fuse to form heterokaryotic cell (plasmogamy).
• Pronuclei then fuse to produce diploid 2n zygote (Karyogamy) - this stage doesn’t happen in mushrooms
• zygote splits and Haploid 1n cells produced via meiosis

1n then 2n split then 1n

Question 9

Answer 9

Zygomycota

Microsporidia

Ascomycota

Basidiomycota

Question 10

What is a opportunistic pathogen? What is an example of something they might take advantage of?

Answer 10

A pathogen that causes disease when they have the opportunity e.g. take advantage of a host with an immunocompromised system
