Question

Which of the following is the best explanation for why cells are considered the smallest units of living things.Cells have the ability to reproduce identical copies of themselves in a process called mitosis.Cells are highly ordered and complex.Cells cannot be seen with the naked eye and are considered microscopic.Cells are the simplest structure to fit all of the characteristics necessary to be considered alive.

Answer 1

Answer:

The answer is: Cells are the simplest structures to fit all of the characteristics necessary to be considered alive

Explanation:

The explanation is that the cell is the smallest unit, characterized by being independent of a certain organism. In human anatomy, all its internal structures are made up of cells, with different functions, sizes and characteristics, and all human physiology is carried out by cells or are started by them, making clear the importance of cells.

Answer 2

Answer:

Cells are the simplest structure to fit all of the characteristics necessary to be considered alive.

Explanation:

The cell (from the Latin cellula, diminutive of cella, ‘hollow’) 1 is the morphological and functional unit of every living being. In fact, the cell is the smallest element that can be considered alive.2 In this way, living organisms can be classified according to the number of cells they possess: if they only have one, they are called unicellular (such as protozoa or bacteria, microscopic organisms); If they have more, they are called multicellular. In the latter the number of cells is variable: from a few hundred, as in some nematodes, to hundreds of billions (1014), as in the case of the human being. The cells usually have a size of 10 µm and a mass of 1 ng, although there are much larger cells.
