Question 2

 

Some fungi, such as the pin mould, can reproduce asexually by producing spores. These spores are not the product of fertilization. Pin mould can be grown on a special jelly called agar. This is done by inoculating the jelly with the mould.

Fungus sporangia

Answer the following questions:

(a) Describe the method which is used to inoculate a dish of agar jelly with pin mould.

(b) The diagram above shows a part of the pin mould growing over its food. Identify the labels A, B, C, D and E.

(c) Describe how the mould feeds, grows and reproduces.

(d) When the mould releases its spores not all of them will germinate and grow into a new mould. Can you explain why?
