Most distinct cell types arise from a single totipotent cell, called a zygote, that differentiates into hundreds of different cell types during the course of development. A single cell is often a complete organism in itself, such as a bacterium or yeast Other cells acquire specialized functions as they mature. A cell is the smallest structural and functional unit of an organism, typically microscopic, consisting of cytoplasm and a membrane, and in most cases containing a nucleus and organelles. Cell structures and their functions explore the structures and functions of major eukaryotic cell organelles Understand how the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, chloroplasts, and ribosomes contribute to cellular function and organization.
All cells can be sorted into one of two groups Plants and animals are made of numerous eukaryotic cells, while many microbes, such as bacteria, consist of single cells. In biology, a cell is the fundamental structural and functional unit of all living organisms Cells can vary enormously in appearance and function. Definition of cell a cell is the basic structural and functional unit of all living organisms, responsible for various life processes and containing essential biological molecules. Learn how cell function depends on a diverse group of nucleic acids, proteins, lipids, and sugars.
The cytoskeleton is a network of long fibers that make up the cell’s structural framework.
