How does cell theory work

Answers

Answer 1
Answer:


The cell theory establishes the fact that cells are crucial to life and so provides a base or foundation from which further elucidation of the cell is carried out. The cell theory is composed of six tenets which are:

1.All living organisms are composed of cells.

2. The cell is the basic unit of life.

3. Cells arise from pre-existing cells.

4. Energy flow occurs within cells

5. Heredity information is passed from cell to cell.

6. All cells have the same basic chemical composition.

The  cell theory forms part of the basic principles that are the foundation for the study of life.

What would most likely happen to a unicellular organism if it was exposed to a hypotonic solution for an extended period of time?

Answers

The answer is that a unicellular organism would swell and burst.

In a hypotonic solution the water concentration of the cell's cytoplasm is lower then that of the hypotonic solution. If unicellular organism is exposed to a hypotonic solution, the water from the solution will enter the organism by the process called osmosis. The aim is to balance water concentration on the inside and outside of the organism. But, that water entering the cytoplasm of the cell will make pressure on the cell membrane. If the excess water cannot be removed from the organism, it will swell and burst.

Answer:

It would swell and then burst.
