What are 5 main organelles and explain how each helps maintain homeostasis within a cell?

Five main organelles that help maintain homeostasis within a cell are the nucleus, mitochondria, endoplasmic reticulum (ER), Golgi apparatus, and lysosomes. The nucleus regulates gene expression and controls cellular activities, ensuring proper responses to environmental changes. Mitochondria produce ATP, providing energy for cellular processes, while the ER synthesizes proteins and lipids essential for cell structure and function. The Golgi apparatus modifies and packages proteins for transport, and lysosomes degrade waste materials and cellular debris, helping to maintain a balanced internal environment.
