A student claims that, according to cell theory, the cell is the basic unit of life, and all cells are created spontaneously. Is this student correct?
No, the student is not correct because the basic unit of life is within a cell.
Yes, the student is correct because all cells are created spontaneously.
Yes, the student is correct because the basic unit of life is the cell.
No, the student is not correct because all cells come from preexisting cells.
No, the student is not correct because all cells come from preexisting cells.
Which organelle is found in animal cells?
plasma membrane
cell wall
central vacuole
chloroplast
The organelle found in animal cells is the plasma membrane.
Which organelle functions as the control center of the cell?
mitochondrion
Golgi apparatus
nucleus
endoplasmic reticulum
The nucleus functions as the control center of the cell.
The correct answer is: No, the student is not correct because all cells come from preexisting cells.
The correct answer is:
No, the student is not correct because all cells come from preexisting cells.
To explain why, we need to understand the principles of the cell theory. The cell theory states that all living organisms consist of one or more cells, cells are the basic units of structure and function in living organisms, and cells come from preexisting cells.
According to the cell theory, cells are not created spontaneously. Instead, new cells arise through cell division, where an existing cell divides into two or more daughter cells. This process is known as cell reproduction.
The idea that cells can arise spontaneously was a popular belief during the 18th and early 19th centuries, known as spontaneous generation. It was believed that living organisms could arise spontaneously from non-living matter. However, this concept was disproven through experiments by scientists such as Louis Pasteur, who demonstrated that cells can only come from preexisting cells.
Therefore, the student's claim that cells are created spontaneously is incorrect according to the cell theory. The basic unit of life is the cell, but cells are not spontaneously created; they come from preexisting cells through the process of cell division.
