Morphology
The phrase is a straightforward adjective–noun combination: 'planktonic' (drifting in water) modifies 'algae' (plant-like organisms), so the overall meaning is directly derived from the constituents. This compositional pattern is predictable and cross-linguistically common, so a learner who knows both words can infer the MWE's meaning.
Etymology
Planktonic algae paints a clear picture: planktonic means drifting or floating in the water and algae are tiny plant-like living things. So planktonic algae means 'tiny algae that float freely in the water as part of the plankton'.
