a) mycelium
b) ascocarp
c) ascospore
d) zygote

Explanation:

• Question 11:
• Centrioles are involved in cell division spindle formation.
• Centrosomes are the main microtubule - organizing centers.
• The synaptonemal complex is involved in meiosis (pairing of homologous chromosomes).
• The centromere is the region where sister chromatids are attached to each other.
• Question 12:
• Mycelium is the vegetative part of a fungus (a network of hyphae).
• Ascospores are the spores produced in asci.
• A zygote is a fertilized egg cell.
• The ascocarp is the fruiting body of fungi like Sordaria that contains asci with spores and can be pear - shaped.

Answer:

• Question 11: C. centromere
• Question 12: B. ascocarp
