A gale disturbed some plants (5)
I believe the answer is:
algae
'some plants' is the definition.
'algae' can be an answer for 'plants' (I've seen this before). I am unsure of the 'some' bit.
'a gale disturbed' is the wordplay.
'disturbed' indicates an anagram (the order of letters is disturbed).
'gale' is an anagram of 'lgae'.
'a'+'lgae'='ALGAE'
Can you help me to learn more?
(Other definitions for algae that I've seen before include "Simple organisms, e.g. seaweeds" , "'Simple plants, such as seaweed (5)'" , "Marine growths" , "Stemless water plants found in a gale" , "Water plants with no true stems or leaves" .)
