What 3 statement describe the cell theory?

Answer 1

The three statements that define cell theory are:

• All living things are composed of one or more cells.
• Cells are the basic life structure of a living thing or organism.
• All cells come from pre-existing cells through reproduction*

*at the present time - at some point there must have been one or more events that created the first cells, and they would have to have been created from inorganic materials.

Answer 2

1) All living organisms are composed of one or more cells

2) Cells are the basic units of structure and function in an organism

3) Cells only come from the reproduction of existing cells.

Answer 3

The three statements that make up the cell theory are that cells are the building block of life, all living things are composed of cells and that all cells come from pre existing cells. These were discovered by three different scientists.

Answer 4

According to 'Cell Theory' the cell is the unit of structure in all organisms.

Answer 5

1) All living organisms are composed of one or more cells

2) Cells are the basic units of structure and function in an organism

3) Cells only come from the reproduction of existing cells.

this answer is from a advanced 9th grade Biology book.

Answer 6

Cell theory has three specific tenets. These tenets are, word for word, as follows. All living organisms are composed of one or more cells. The cell is the most basic unit of life. All cells arise from preexisting, living cells.

Answer 7

The generally accepted parts of modern cell theory include:

1. The cell is the fundamental unit of structure and function in living things.
2. All cells come from pre-existing cells by division.
3. Energy flow (metabolism and biochemistry) occurs within cells.
4. Cells contain hereditary information (DNA) which is passed from cell to cell during cell division
5. All cells are basically the same in chemical composition.
6. All known living things are made up of cells.
7. Some organisms are unicellular, i.e., made up of only one cell.
8. Others are multicellular, composed of a number of cells.
9. The activity of an organism depends on the total activity of independent cells.

Answer 8

1. All organisms are made of one or more cells

2. The cell is the basic unit of all living things

3. All cells come from existing cells

the fist two were stated by Theodor Schwann and the last one was stated by Rudulf Virchow.

Answer 9

1) all living things are composed of cells.

2) cells are the basic units of structure and function in living things.

3) new cells are produced from existing cells.
