Who said that cells come from cells?
Rudolf Virchow said that all cells come from existing cells.
Who said that all cells arise from division of existing cells?
virchow
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 cells come only from other cells?
ME
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.
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.
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.
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.
Gametes are said to be?
sex cells, like sperm or eggs in humans. They are normally haploid.
How do you write said in a syllable form?
Said only has one syllable. This means the whole word is the syllable.
Genes carried only x-chromosomes are said to be?
female cells
What did Schwann and Schleiden say on cells?
Schleiden and Schwann came up with what is known as "The Theory of Cells" or "Cell Theory." The main principles of "Cell Theory" are: 1. All living things are made up of cells. 2. Cells are the smallest units of living things 3. Cells only rise from existing cells. Schleiden said that All plants are made up of many different kinds of cells. Schwann added to that and said that All animal are made up of many different kinds of cells. Schwann also said that growth and development is due to the division of cells.
