yes according to cell theory all cells arise by division in previously existing cells.
yes. mitosis or meiosis.

Somatic cells are body cells which are important part of the body's multicellularity and function. So they should have same DNA code in order to maintain a balance in the functioning of the body. And except sex cells (gamates) all the cells of human body (i.e. somatic cells) have the same DNA code. Another reason for this is mitosis. As body cells arise from mitosis, the division is conservative and doesn't involve any process of inducing variation in the cells, hence all the cells originating from it have the same DNA code.
all cells arise from the pre existing cell and the process involved in division of cells is mitosis due to which the daughter cell are identical to their parent cells........

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.
he suggested that all cells arise from cells that already exist.
The idea that all cells must come from pre-existing cells is known as cell theory. This theory states that cells are the basic unit of life and that all living organisms are composed of cells. It also proposes that cells arise from pre-existing cells through cell division.
Biogeographic observations indeed suggest that a evolutionary process caused new species to arise, through the process we call natural selection. This is due to an animals adaptability in it's environment.
