Question

Which of the following is not the
part of modern cell theory?
a) All living things are made up of
one or more cells
b) The cell is a functional and
structural unit of life
c) Energy flow takes place within the
cell
d) All cells do not have the same
chemical composition​

Answer 1

Answer:

All cells arise from pre-existing cells.

Explanation:

Cell theory is the historic scientific theory which is universally accepted. It was given by Schleiden and Schwann in 1838. it explained that living organisms are made up of cells, that are the basic structural unit of all organisms and that all cells come from pre-existing cells.

So the correct answer is 'All cells arise from pre-existing cells'.

Answer 2

Answer:

The correct option is (d) All cells do not have the same chemical composition.

Cell theory was given by  Theodor Schwann and Matthias Jakob Schleiden.

Its major points are

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

2. The cell is the most basic unit of life.

3.  In the year 1855, Rudolf Virchow stated  Omnis cellula e cellula which means that all cells arise only from pre-existing cells.

Explanation:

Living beings are made up of cells and their products. Cells are the basic fundamental in the body. Cells are units of function in living organisms, that is, the activities of an organism are the sum total of the activities of its cells.

The accepted parts of modern cell theory are as follows.

1. All the known living things in the world are made up of one or more cells.
2. All living cells arise from pre-existing cells by cellular division.
3. The cell is considered the fundamental unit of structure and function in all living organisms.
4. The activity of a living organism depends on the total activity of independent cells in the body.
5. Energy flow occurs within the cells of living beings.
6. Cells contain DNA the nucleic element found specifically in the chromosome of the cell nucleus and RNA which is also found in the cell nucleus and cytoplasm.
7. All cells are basically the same in chemical composition in organisms of similar species.
