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'm not certain of the 'some' bit.
'a gale disturbed' is the wordplay.
'disturbed' indicates an anagram.
'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" .)
