They transform chemical energy from food into an energy form the cell can use. Mitosis is the process of division in the nucleus of a cell in which two identical daughter nuclei are produced, each containing two sets of chromosomes. Nucleus is the structure in a eukaryotic cell that contains the cell's hereditary material. Organelles are structures inside the cell that have a specific function. They include the endoplasmic reticulum, mitochondria, nucleus, and ribosomes.
Proteins are substances made up of amino acids.
A cell's structures are built chiefly of proteins. Proteins called enzymes speed up chemical reactions in a cell. Ribosomes are tiny bodies in a cell that are involved in protein production. It carries out DNA's instructions for making specific proteins. Somatic cells are all the cells in a multicellular organism except the sex cells.
