All living organisms are composed of cells, some have only one cell and are called unicellular and others have many cells and are known as multicellular. The cell is the smallest part of a living organism.
The cells of both animals and plants have three vital functions: nutrition, relation and reproduction. The cells parts consist of a membrane, the cytoplasm and the organelles, where the nucleus is the cell’s most important organelle. The genes are found there as well as the hereditary characteristics of all living organisms. We look so alike our parents because we receive their hereditary genes.
During this educational videos dedicated to Happy Learning children we will see that all living organisms, no matter how big or small, are made up of cells and that all of them are fundamental, imperative for our beautiful life’s balance.
