Iron, copper, phosphorus, selenium and zinc are the first ones that come to mind.
calcium
No, cells are the most basic living structural units.
To support a living organism
these elements are macronutrients.
Carbon, Hydrogen, and Oxygen
Most definately. An entire world of living cells. Very possibly an unlimited amount.
carbon, oxygen, hydrogen, nitrogenAlthough all of these elements are found in living cells, the most abundant are carbon, hydrogen and oxygen (for carbohydrates and lipids) and nitrogen (for proteins and nucleic acids).
Calcium is made of atoms, not cells, as calcium by itself is a non-living element whereas cells are made up of thousands and thousands of elements that work in unison to produce a living cell.
Life threating to all forms of living cells, and to the elements of life.
All known living things have cells. There are many non-living things that do not have cells.
Cells are indeed considered the basic structural and functional units of living organisms, carrying out essential processes for life such as metabolism and reproduction. On the other hand, elements are the basic units of matter that make up non-living things, such as rocks, water, and air. However, elements can also be essential for living organisms as they are the building blocks of molecules like proteins and DNA.
1. All living things are made up of one or more cells. 2. Cells are the basic living units within organisms. The chemical reactions of life take place within the cells. 3. All cells arise from pre-existing cells through the process of cell division.
