Las células: fundamentos de la vida en plantas y animales

Cells are the fundamental units of life, visible only under a microscope. They are diverse, performing various functions. Animal and plant cells share key structures like the cell membrane, cytoplasm, nucleus, ribosomes, and mitochondria. Plant cells also have a cell wall, chloroplasts, and a vacuole. These components enable the incredible diversity of life.
