In the given case, even after boiling hay infusion for one hour, growth was observed in the flask after one day. It can be due to certain factors like the hay infusion may have been comprising some endospore, which is resistant to heat or may comprise some kinds of bacteria that can withstand high temperatures.  

Because of which, even after heating the infusion for one hour, it did not get influenced by the heat and got the chance to grow when it got optimum temperature again at the time when the sample was left as such.

Actin filaments: - are flexible double strands of the protein actin . They lead the intracellular movement of organelles  and molecules  and stabilize mechanically the plasma membrane .

Microtubule: - are rigid hollow cylinders of the proteins α- & β-tubulin

They are responsible for the position and stability of ER and  Golgi-Apparatus , help to divide & move chromosomes during mitosis  and organize the growth of the cell wall .

Intermediate filaments: - are robe like fibres of different proteins which give

mechanical support
