4 haploid sperm cells are made from 1 diploid cell
The vacuoles are the membranous sacs which are filled with fluid. These spaces inside the vacuoles are free of the cytoplasm and are lined by the membrane. These vacuoles serve the purpose of storage, digestion, ingestion, and excretion. The vacuoles allow the plant cells to attain big size without the accumulation of the bulk.
The vacuoles are present in both plant and the animal cells, however, their size in plant cells is larger. No proteins or microtubules composes these vacuoles.
Hence, the blank can be filled with 'membranous sacs'.
If lots of things were changed (independent variable) then you wouldn’t know what caused the trend(s) in your results so you have to control all but one variable so you know that you are just changing the one thing so that is the only thing that could cause the trend. I hope that made sense
