Viruses are considered an exception to the cell theory because they lack the ability to carry out metabolic processes independently, replicate, or grow without a host cell. They are not considered living organisms because they do not meet all the criteria necessary for being classified as a cell.
Scientists could use the cell theory to determine if an object is an organism by examining its structure under a microscope for evidence of cells. If the object is composed of cells with a defined nucleus and membrane-bound organelles, it would align with the principles of the cell theory and likely be considered an organism. Additionally, observing characteristics such as growth, reproduction, and response to stimuli would further support this classification.
Viruses are not considered part of the cell theory because they are acellular entities that require a host cell to replicate.
The cell theory states that all living organisms are composed of cells, while the organism theory suggests that cells are the building blocks of living organisms. In essence, the cell theory focuses on the fundamental unit of life being the cell, whereas the organism theory looks at how cells come together to form complete organisms.
No, one cell cannot be considered a living organism. Living organisms are made up of multiple cells that work together to carry out life processes. A single cell is the basic unit of life, but it does not have all the characteristics of a living organism on its own.
only in a host cell
The bacteria and blue green algae are exception of the cell theory because they are devoid of the true nucleus or well organized nucleus.
The first cell did not come from a preexisting cell and viruses
Viruses are considered an exception to the cell theory because they lack the ability to carry out metabolic processes independently, replicate, or grow without a host cell. They are not considered living organisms because they do not meet all the criteria necessary for being classified as a cell.
cell theory is accepted today because it is a unit of living organism.

he stated that the cell is a structural unit of an organism.
Viruses are not considered part of the cell theory because they are acellular entities that require a host cell to replicate.
which statement represents an exception to the cell theory
It's a single cell.
yes!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! take your pick of any cell in the human body none of them are considered an organism, they are a layer of organization in the human body.
yes, plants have cell walls but animal cells do not.
