Mammalian cells

Mammalian cells are the basic building blocks of mammals, including humans. They are tiny, specialized structures that carry out essential functions like energy production, growth, and repair. Each cell has a nucleus that holds genetic information, surrounded by a flexible membrane that controls what enters and exits. Inside, various components called organelles work together to perform tasks such as making proteins and generating energy. These cells group together to form tissues and organs, enabling complex life processes. Despite their size, mammalian cells are sophisticated systems essential for health and survival.
