What is a Plant Cell?Plant cells are eukaryotic cells that vary in several fundamental factors from other eukaryotic organisms. Both plant and animal cells contain a nucleus along with similar organelles. One of the distinctive aspects of a plant cell is the presence of a cell wall outside the cell membraneIn general, animal cells are smaller than plant cells. Its uneven form is another distinguishing feature. This results from the lack of a cell wall. However, because both plant and animal cells descended from eukaryotic cells, they share some cellular organelles.NucleusThe nucleus is an organelle that houses a number of different sub-organelles, including chromatins, nucleoli, and nucleosomes. DNA and other genetic materials are also present.Nuclear MembraneAround the nucleus lies a double-membrane structure. The nuclear envelope is another name for it.NucleusThe nucleus is an organelle that houses a number of different sub-organelles, including chromatins, nucleoli, and nucleosomes.
