Question

What is bilocular trilocular unilocular

Answer 1

The main word here is ‘-locular’ which means it is referring to a loculus, which is nothing but a cavity or a chamber, mostly used to refer to the number of chambers in the ovary of a flower.
Unilocular (uni- meaning one) means the ovary has only one chamber.
Bilocular (bi- meaning two) means the ovary has two chambers.
Multilocular (multi- meaning more than two) means the ovary has more than two chambers.
