Question

what is the main function of cytoplasm in a plant cell?
to make proteins
to produce steroid hormones
to fill the space between the cell membrane and the nucleus
to break down sugar and release energy that the cell can use

Explanation:

The cytoplasm is the jelly - like substance that fills the space between the cell membrane and the nucleus in a plant cell. Protein synthesis occurs on ribosomes, steroid hormone production is not a main function of plant cell cytoplasm, and sugar breakdown for energy mainly occurs in mitochondria (though glycolysis starts in cytoplasm but not the main function of cytoplasm).

Answer:

to fill the space between the cell membrane and the nucleus
