Question

Select ALL of the following that occur during spermiogenesis:

Group of answer choices

Microtubules form a flagellum

Proteolytic (digestive) enzymes are bundled in an acrosomal cap

The nucleus condenses

  Excess cytoplasm is shed

Answer 1

Answer- all the options are correct.

a) Microtubules form a flagellum

b) Proteolytic (digestive) enzymes are bundled in an acrosomal cap

c) The nucleus condenses

d) Excess cytoplasm is shed

Reason- Spermiogenesis occurs in the following phases:-

Golgi phase:- in this, the spermatid DNA undergoes packaging and becomes highly condensed.

Acrosome phase:- in this phase, golgi apparatus surrounds the condensed nucleus, forming the acrosomal cap. these golgi apparatus creates the enzymes which helps in acrosome formation.

Formation of tail:- The centrioles of the cell elongates to form the tail of the sperm. Centrioles are made up of microtubules.

Maturation phase:- wherein the excess cytoplasm is phagocytised by the surrounding Sertoli cells.
