Morphology
The meaning is directly derivable from combining 'cell' (a microscopic living unit) with 'nucleus' (the cell compartment containing DNA/RNA); together they denote that specific part of a cell. Although scientific in register, the composition is straightforward and cross-linguistically common, so a B1 learner who knows both constituents will understand it.
Etymology
Cell nucleus comes from the words cell and nucleus, where nucleus means 'little kernel' or 'small center'. Imagine a tiny seed in the middle of the cell that holds the instructions and controls growth and the making of new cells, so the name means the cell's control center.
