How does Macronucleus help the organism in its day to day life?

The macronucleus is a vital organelle in certain protozoans, particularly ciliates, and it plays a crucial role in regulating everyday cellular functions. It is responsible for controlling gene expression, metabolism, and the synthesis of proteins, which are essential for growth and reproduction. By managing these processes, the macronucleus enables the organism to respond effectively to environmental changes and maintain homeostasis. Overall, it supports the organism's survival and adaptability in diverse habitats.
