28) Yeast cells reproduce quickly by budding. This is a form of( asexaul ) reproduction so all the yeast cells (). < should you write a word or a sentence here ? 
anyway let me explain the answer to you ... why its asexaul reproduction ? because it doesn't involve 2 parents one parent is needed only , its  without gametes ( sex cells) , pollination , fertilisation and dispersal . 
We know if this is an asexaul reproduction if it :-involves one parent .- the characteristics of the  offspring is identical to the parent . - the offspring is identical to the parent genetically .- the reproduction rate is rapid because of the favourable conditions . 

thats it , hope you got the point . 
Pray for me . best of luck
