WebMar 8, 2024 · Over time, some cells became more complex. Called eukaryotes (Yu-KAER-ee-oats), these now make up animals, plants and fungi. Some one-celled organisms, such as yeasts, also are eukaryotes. These cells are all like single-family houses — with walls and doors making up separate rooms. A membrane encloses each organelle in these cells.
