The cell wall is used to keep the shape of the cell the same.

The cell membrane of a plant cell is important because it acts as a barrier that controls the movement of substances in and out of the cell. It helps maintain the cell's internal environment, regulate cell communication, and provide structural support to the cell. Additionally, the cell membrane plays a role in cellular recognition and interactions with neighboring cells.

The nucleus in an animal cell contains the cell's genetic material in the form of DNA, which provides instructions for cellular functions. It regulates gene expression and controls the activities of the cell by directing the synthesis of proteins and coordinating cell division. Additionally, it is responsible for storing and protecting the DNA.
Cell contact. Hormones control just about every bio-thing. Yes, there are specific examples [available]. One exception is Cell size: when a Cell 'gets too big', it will be signaled to Divide. By the way, all of the above mentioned signaling occurs via the use of enzymes.
