The function of the nucleus in the plant cell is to store the plant's DNA and control the activity of the cell through protein synthesis. The nucleus is enclosed by the nuclear membrane, which has pores for the passage of RNA and proteins. The nucleus contains the nucleolus and chromatin.
The nucleolus produces ribosomal RNA while chromatin is a combination of DNA, protein and RNA. Other organelles found in a plant cell outside the nucleus are the vacuole, Golgi apparatus, cytoplasm, mitochondria, smooth endoplasmic reticulum and free ribosomes. Unlike animal cells, plant cells contain chloroplasts, which are disc-shaped and contain chlorophyll, an important substance for photosynthesis.
