Cells

Cells are the basic building blocks of all living organisms. They are tiny units that carry out essential functions necessary for life, such as producing energy, growing, and reproducing. Each cell has a membrane that controls what enters and exits, a nucleus that contains genetic information, and various structures called organelles that perform specific tasks. Think of cells as the smallest functional units that work together to form tissues, organs, and entire organisms, allowing life to exist and thrive in diverse forms.
