The nucleus in both plant and animal cells “specializes” the cells so they can do different things- for example, a liver cell or a muscle cell do different things.  Thinking about plants or trees, what special functions might different cells in a tree or plant do?

Plant cells are the basic unit of life in organisms of the kingdom Plantae. They are eukaryotic cells, which have a true nucleus along with specialized structures called organelles that carry out different functions. Plant cells have special organelles called chloroplasts, which create sugars via photosynthesis. They also have a cell wall that provides structural support

The answer is reflection.
