A cell is composed primarily of the elements hydrogen, carbon, oxygen and nitrogen. These molecules make up the organic molecules like carbohydrates, proteins, fats, and nucleic acid that compose the different parts of the cell. These different parts of the cell are the plasma membrane, nucleus,...
Humans are composed of what cells? What are killer T-cells made of? Where do all cells come from? What do amacrine cells do? What do oxyphil cells do? What cells are formed by replicating B cells? What is an organism made up of many cells called?
What are genes composed of? Genes DNA (short for deoxyribonucleic acid) is often referred to as the blueprint of the cell. Note that chromosomes, are comprised of DNA, which contains the code for protein synthesis and in turn traits, such like eye color and height. ...
1. All Living Organisms Are Composed Of Cells The first postulate of cell theory states something that we all find pretty obvious today—all living organisms are made of cells. However, if you look back a few hundred years ago, researchers had a hard time explaining this simple concept to t...

But they discovered a great deal, including the cells composing animal and plant tissues, microscopic organisms, and some of the structures within cells. By the mid-1800s, these discoveries led to the cell theory, which states that all living things are composed of cells and that all cells ...
