I think an issue here is that taxonomic and colloquial definitions don't always agree.
Spiders are colloquially bugs, but they're not taxonomically "true bugs" (which is itself a colloquialism for Hemiptera). Tomatos are colloquially vegetables but taxonomically fruits...but afaik vegetable is a purely colloquial term anyway.
And as someone else in the thread mentioned, colloquial berries are not always taxonomic berries.
So...colloquially, "plants" sorta means, "macroscopic multicellular living non-animal thing," but taxonomically it's something else.
And environment
DISPLAY
andPATH
in particular.
