Plant Cell Nucleus
The plant cell nucleus is a membrane-bound organelle found within plant cells that contains the cell's genetic material in the form of DNA. It is responsible for controlling the cell's activities, including growth, metabolism, and reproduction. The nucleus is typically spherical in shape and contains a dense structure called the nucleolus, where ribosomal RNA is produced. The nucleus is essential for the regulation of gene expression and the transmission of genetic information to offspring during cell division.
