Answer:
Cells do not generally allow such materials to go in because they are having a cell membrane outside. The cell membrane only allows the materials which are required for the growth of the cell such as water and minerals.

The correct answer is :
Some substances but not other can cross the (blank ) membrane of a cell. The blank is to be filled with either cell or plasma. Cell membrane or plasma membrane is the living boundary of a cell which is made of phospholipid. It is a semi-permeable or differentially permeable membrane. It only allows small and non-polar molecules to pass through it. It prevents polar ions or molecules to pass through it
S phase is the DNA synthesis phase. During this portion of the cell cycle, the cell replicates its entire complement of DNA. It also forms the centrosome, which is the microtubule-organizing center that will eventually help the cell pull apart the DNA that will be divided between daughter cells.
