What else can I help you with?
Who first said that all cells were made from cells?
Rudolf Virchow first stated the principle "omnis cellula e cellula," which means that all cells arise from pre-existing cells. This observation was made in 1855 during his studies on cell division and growth.
Do cells come from pre existing cells?
yes; if a cell is said to be present, then it was originated by the division of it's mother cell.
Who said that cells come from cells?
Rudolf Virchow said that all cells come from existing cells.
Who said that new cells form only from existing cells?

Who said that all cellls come from other cells?
Rudolf Virchow, a German scientist, is credited with the statement "Omnis cellula e cellula" which means "every cell originates from another existing cell." This concept is a fundamental principle in cell theory and highlights the idea that all cells arise from pre-existing cells through cell division.
Who said cells only come from preexisting cells?
Matthias Schleiden, Theodor Schwan, and Rudolph Virchow all stated that cells must come from existing cells. This is known as the cell theory.
What was Rudolf virchow's contribution to the cell theory?
In 1838, Theodor Schwann and Matthias Schleiden were enjoying after-dinner coffee and talking about their studies on cells. It has been suggested that when Schwann heard Schleiden describe plant cells with nuclei, he was struck by the similarity of these plant cells to cells he had observed in animal tissues. The two scientists went immediately to Schwann's lab to look at his slides. Schwann published his book on animal and plant cells (Schwann 1839) the next year, a treatise devoid of acknowledgments of anyone else's contribution, including that of Schleiden (1838). He summarized his observations into three conclusions about cells:The cell is the unit of structure, physiology, and organization in living things.The cell retains a dual existence as a distinct entity and a building block in the construction of organisms.Cells form by free-cell formation, similar to the formation of crystals (spontaneous generation).We know today that the first two tenets are correct, but the third is clearly wrong. The correct interpretation of cell formation by division was finally promoted by others and formally enunciated in Rudolph Virchow's powerful dictum, Omnis cellula e cellula...: "All cells only arise from pre-existing cells".The modern tenets of the Cell Theory include:All known living things are made up of cells.The cell is structural & functional unit of all living things.All cells come from pre-existing cells by division. (Spontaneous Generation does not occur).Cells contains hereditary information which is passed from cell to cell during cell division.All cells are basically the same in chemical composition.All energy flow (metabolism & biochemistry) of life occurs within cells.
Do all new cells come from preexisting cells?
yes; if a cell is said to be present, then it was originated by the division of it's mother cell.
Do cells come from preexisting cells according to the cell theory?
YES! One of 3 main parts of the Cell Theory.1. Cells are the basic unit of structure and function in living things.2. All living things are made of cells.3. ALL CELLS COME FROM OTHER (CELLS)Cells divide through Mitosis. (If you need to know more about cell division, search "mitosis")
During cell division the number of cells increase by?
Each cell splits into two halves. Therefore, each cell division increases by two - or is said to double each time.
Enumerate different scientists and their contributions to cell theory?
Matthias Schleiden: Co-founded cell theory with Theodor Schwann, proposing that all plants are composed of cells. Theodor Schwann: Co-founder of cell theory; proposed that all animals are also composed of cells. Rudolf Virchow: Established the concept of "omnis cellula e cellula," asserting that cells arise only from pre-existing cells.
Explain the three concepts that make up the cell theory?
1) all life is composed of cells2) cells are the smallest living unit3) all cells come from pre-existing cellsThree statements which create Cell Theory are-All living organisms are made from cells either multicellular or unicellular.The cell is the basic unit of life.All cells exist from pre-existing cell.The modern version of the cell theory include the ideas thatEnergy flow occur within the cell.Hereditary information (DNA) is passed through one cell to other.All cells have the same basic chemical composition.
