Pretend you are a teacher preparing a quiz for the text I will provide. 
            Each quiz question should follow the format below. 
            Ensure that you carefully recheck the questions and answers for accuracy. 
            The output should be a ready-to-use list of dictionaries for the Python eval function:

            [

                    "question": "WRITE THE QUESTION HERE",
                    "options": ["A) OPTION_1", "B) OPTION_2", "C) OPTION_3", "D) OPTION_4"],
                    "answer": INDEX_OF_CORRECT_ANSWER_IN_OPTIONS_LIST,
                    "explanation": "EXPLAIN WHY THE ANSWER IS CORRECT"

examining the cellular components of these organisms in terms of their chemical 
structures, locations, and biological functions. Additionally, it involves studying 
the various biological reactions that occur within these living cells, including 
biosynthesis and creation, as well as catabolism and energy production. 
Cell 
  The cells of the human cheek have an outer membrane as the delimiting 
structure of the cell. Inside each cell is a dense membrane-bound structure called 
a nucleus. This nucleus contains the chromosomes, which in turn contain the 
genetic material, DNA.  
A cell is the smallest unit that is capable of performing life functions. 
All cells have a cell membrane, and membrane functions control what enters and 
exits the cell to maintain an internal balance called homeostasis. It provides 
protection and support for the cell.  
 
 
Cells differ greatly in size, shape, and activity. For example, Mycoplasmas, 
the smallest cells, are only 0.3 µm in length, while bacteria could be 3 to 5 µm. 
The largest isolated single cell is the egg of an ostrich. Among multicellular 
organisms, human red blood cells are about 7.0µm in diameter. Nerve cells are 
some of the longest cells. Cells also vary greatly in their shape. They may be disc-
like, polygonal, columnar, cuboid, thread like, or even irregular. The shape of the 
cell may vary with the function they performs. 
 
 
 
 
 
 
A eukaryotic cell contains a membrane separating the nucleus from the rest of 
the cell components. 
A prokaryotic cell does not have a membrane that separates the nucleus from the 
rest of the cell components. 
❖ Eukaryotic cells are of two types: animal cells and plant cells. 
 
 
 
 
 
 
 
 
 
 
An animal cell contains: 
1. Cell membrane 
It protects the cell and is a selectively permeable membrane. It consists of 40% 
lipids, 60% proteins, and some specialized enzymes. It binds to specific 
components, such as enzymes, as it contains receptors for each on its surface. 
2. Nucleus 
The nucleus is the information center of the cell, containing DNA and proteins 
such as histones and protamines. It houses more than 95% of the cell's nucleic 
acids and contains a small structure called the nucleolus. The nucleolus is made 
up of large complexes of RNA molecules, including mRNA, which carries 
genetic information and plays a key role in protein synthesis. 
3. cytoplasm 
It contains RNA, glucose, and metabolites such as urea, uric acid, creatinine, 
enzymes, etc. The following components are found in the cytoplasm: 
A. Mitochondria 
Mitochondria are the energy-producing centers of the cell, as they are capable 
of synthesizing ATP molecules. They are also involved in oxidation-reduction 
reactions, as well as the oxidation of fatty acids, proteins, and other substances. 
B. The endoplasmic reticulum (ER) consists of the following: 
The smooth ER (SER) is involved in the synthesis of steroids, fats, and 
complex glycoproteins. It can also be used to detoxify
