Cell membrane: The cell membrane controls the movement of substances in and out of the cell, maintaining the internal environment and allowing essential nutrients to enter while waste products exit.
Cytoplasm: The cytoplasm is the gel-like substance inside the cell that surrounds the organelles, providing a medium for chemical reactions and holding the cell’s structures in place.
Nucleus: The nucleus is the control center of the cell, containing genetic material that regulates cell activities and facilitates growth and reproduction.
Mitochondria: Mitochondria are the site of aerobic respiration, producing ATP, which supplies energy for various cellular activities.
Ribosomes: Ribosomes are responsible for protein synthesis within the cell, assembling amino acids into proteins based on genetic instructions.
