Mitochondria and chloroplasts are considered exceptions to the cell theory because they contain their own DNA and can replicate independently of the cell. This suggests they may have originated from free-living prokaryotes through endosymbiosis. Additionally, their ability to produce energy (ATP in mitochondria) and perform photosynthesis (in chloroplasts) further distinguishes them from typical cell organelles.

Exceptions of cell theory of every point of the cell theory?
Viruses
Which type of pathogens is one of the exceptions to the rule of typical cell structure?
Viruses are one of the exceptions to the rule of typical cell structure. They are not considered cells because they lack cellular structures, such as a nucleus, cytoplasm, and organelles. Instead, viruses consist of genetic material (DNA or RNA) enclosed in a protein coat.
Which organelles is considered substitute of lysosome in plant cell?

What are the 3 exceptions to cell theory?
Cell theory states that all living organisms are composed of cells, but there are notable exceptions. First, viruses, which are not considered living organisms, lack cellular structure and cannot reproduce independently. Second, the first cells, or prokaryotes, are thought to have originated from non-cellular entities, blurring the lines of the theory's definition. Lastly, the existence of multinucleate cells, such as skeletal muscle fibers and certain fungal cells, challenges the idea that a cell should contain a single nucleus.
Why cytoplasm is not considered to be a cell organelle?
Cytoplasm is not considered a cell organelle because it is a jelly-like substance that fills the cell and surrounds the organelles, providing a medium for their activities. It does not have a membrane surrounding it like organelles do, and it is present in both prokaryotic and eukaryotic cells.

Viruses
Are cell walls considered organelles in a cell's structure?
No, cell walls are not considered organelles in a cell's structure. Organelles are membrane-bound structures within a cell that have specific functions, while cell walls are rigid structures found outside the cell membrane that provide support and protection to the cell.
How are organelles and organs different?
organelles parts of a cell organ - considered of several tissues
Which type of pathogens is one of the exceptions to the rule of typical cell structure?
Viruses are one of the exceptions to the rule of typical cell structure. They are not considered cells because they lack cellular structures, such as a nucleus, cytoplasm, and organelles. Instead, viruses consist of genetic material (DNA or RNA) enclosed in a protein coat.
Is cytoplasm considered an organelle within a cell?
No, cytoplasm is not considered an organelle within a cell. It is a jelly-like substance that fills the cell and surrounds the organelles. Organelles are specialized structures within the cell that perform specific functions.
What is the basic structural and functional units of the body?
The cell. An organism can be composed of one or many cells. Cells are composed of organelles, but organelles cannot function alone (with exceptions).
what are some exceptions to the cell theory?
Presence of extra-chromosomal DNA: Mitochondria and chloroplasts
Are organelles the basic functional unit of life is this a cell theory?
No, organelles are not the basic functional unit of life according to cell theory. The cell is the basic structural and functional unit of all living organisms. Organelles are specialized structures within cells that carry out specific functions.
Does an animal cell has nucleus and organelles?
Yes, an animal cell has a nucleus which contains genetic material, and various organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes that perform specific functions within the cell.
Which organelles is considered substitute of lysosome in plant cell?
im not sure
What organelles store information and is considered the control center of the cell?
The nucleus.nucleus
