Answer:
The correct statements are:
Eukaryotes is a term used for all the organisms whose cells contain a well-defined nucleus in them.
Their cells also contain other membrane-bound organelles like mitochondria, Golgi apparatus, chloroplast, et cetera.
These cells generally have a larger size as compared to the cells of prokaryotes.
Eukaryotes can be unicellular (such as euglena, paramecium, diatoms, chlorophyta, candida et cetera) as well as multi-cellular (such as plants, animals, humans et cetera)
