Question

which principle of cell theory best supports the idea that new cell will replace damaged cells in a scraped knee?

A.)All living things are made of one of more cells

B.) Cells are the basic unit of life

C.) All cells come from other cells

D.) The nucleus of cells in animals reproduces when exposed to air

Answer 1

Answer:

B) Cells are the basic unit of life

Explanation:

Cell theory states that cells are the basic morphological and functional units for the maintenance of life, that is, all living beings must be formed by cells, so it is impossible for a living being without at least one cell in its constitution. . This concept explains our body's need to replace the cells that we lost for some reason.

In that case, we can say that cell theory states that cells are the basic unit of life and this supports the idea that a new cell will replace damaged cells in a scratched knee.

Answer 2

The principle of the cell theory that best supports the idea that new cells will replace damaged cells in a scraped knee would be the one that says all cells come from other cells. C would, thus, be the right option.

Recall the 3 major principles of the cell theory:

1. Cell is the basic unit of life
2. All living organisms are composed of cells
3. Cells arose from preexisting cells

The third principles relies on the capacity of cells to divide and produce daughter cells. Cells can divide in two ways depending on whether they are vegetative or sex cells.

• Vegetative cells divide by mitosis and produce 2 daughter cells each
• Sex cells divide by meiosis and produce 4 daughter cells each

In the case of damages to cells due to scraped knee, the healthy cells around the bruised region would divide by mitosis and produce new cells that will replace the damaged cells. Once the damaged cells have been replaced, the bruised region heals.
