Yes, you are correct. In biology, a cell is the fundamental structural and functional unit of life. It is the smallest, self-contained entity that can carry out all the processes necessary for life. Cells are the building blocks of all living organisms, from single-celled microorganisms to complex multicellular organisms like plants, animals, and humans.
Cells vary in size, shape, and function, but they all share certain basic features. Each cell is enclosed by a cell membrane that separates its internal components from the external environment. Within the cell, various organelles perform specific functions, such as the nucleus for storing genetic material, the mitochondria for energy production, and the endoplasmic reticulum for protein synthesis.
Cells carry out essential life processes, including metabolism, growth, reproduction, and response to environmental stimuli. They can exist independently, like in unicellular organisms, or work together to form tissues, organs, and systems in multicellular organisms. Understanding the structure and function of cells is crucial in comprehending the complexity of life and the biological processes that sustain it.
