In a cell of plants, animals, fungi and protists, a well organised nucleus is present (1.e., such a nucleus is bounded by an envelope and has nucleolus) and membrane-bound organelles such as endoplasmic reticulum, mitochondria, chloroplasts and Golgi apparatus are present. Such cells are called eukaRead more
