PLEASE,elaborate John Dalton's statement,"all living things are made up of cells".
You have posted this several times, I guess it is time to challenge you. Do you have a reference for that statement from John Dalton? I don't believe he said it at all. In fact, I think you mean his written statement " All matter is made of atoms." included in his Atomic Theory. This is quite different from cellular theory, of which, Dalton did not work on.
Did your teacher tell you this?
Yes,our teacher told us.Our teacher also told us to list cell organelles of plant cell and animal cell.I hope you can help me.I don't know how to elaborate this statement.

Elaborating on the statement "all matter is made up of cells", which was not made by John Dalton.
Is all matter made up of cells? if not, then how does the characteristic of life...that all organisms are made up of cells...also work for nonliving things?
All matter is made up of atoms. Most living matter is made of atoms arranged in living cells. Non-living matter is made of just atoms.
All organisms are made of cells.
However, water, air, and other nonliving [and never living before] types of matter are all made up of elements and compounds. Bodies which are living or had lived typically are made of carbon, oxygen, and hydrogen.
Cell theory was eventually formulated in 1839. This is usually credited to Matthias Schleiden and Theodor Schwann. However, many other scientists like Rudolf Virchow contributed to the theory. It was an important step in the movement away from spontaneous generation.
The three tenets to the cell theory are as described below:
All living organisms are composed of one or more cells.
The cell is the basic unit of structure and organization in organisms.
Cells arise from pre-existing cells.
But John Dalton had nothing to do with this, nor ever said it according to my extensive readings.
Thank you very much!!
John Dalton did not actually make the statement "all living things are made up of cells." This statement is commonly attributed to Theodor Schwann and Matthias Schleiden, who, in the 19th century, proposed the Cell Theory, which states that all living organisms are composed of cells. However, I can explain the Cell Theory and how it was developed.
The Cell Theory is a fundamental concept in biology that describes the basic unit of life. It consists of three main principles:
1. All living organisms are composed of one or more cells: This means that every living thing, from the simplest unicellular organisms to complex multicellular organisms like humans, is made up of cells.
2. The cell is the basic unit of structure and function in living organisms: Cells are the smallest structural and functional units of living organisms. Each cell has specific structures and performs specific functions necessary for the organism's survival.
3. Cells arise only from pre-existing cells: New cells are generated through cell division, where existing cells divide and give rise to daughter cells. This principle suggests that life does not arise spontaneously but through reproduction of existing cells.
The Cell Theory emerged from the work of several scientists. In the early 19th century, Matthias Schleiden and Theodor Schwann independently studied plant and animal tissues, respectively. Schleiden concluded that plants are composed of cells, while Schwann proposed that animals are also made up of cells. Their combined research laid the foundation for the Cell Theory.
Later, the contributions of Rudolf Virchow solidified the third principle of the Cell Theory. Virchow stated that cells can only arise from pre-existing cells, contradicting the previously accepted theory of spontaneous generation.
In summary, John Dalton, a chemist and physicist, did not specifically make the statement "all living things are made up of cells." Instead, this fundamental concept was developed based on the work of various scientists, primarily Matthias Schleiden, Theodor Schwann, and Rudolf Virchow.
