Nucleoplasm is the gel-like substance that fills the nucleus of a eukaryotic cell. It contains:

* Chromatin: The complex of DNA and proteins that makes up chromosomes.

* Nucleoli: Sites of ribosome synthesis.

* Other nuclear components: Enzymes, transcription factors, and other molecules involved in DNA replication, transcription, and RNA processing.

Plant cells are eukaryotic cells, meaning they have a nucleus. Therefore, they also have nucleoplasm.
