What is a Cell?
A cell is a basic and fundamental unit of life. Therefore, if we were to break an organism apart to the cellular level, the smallest independent component - which would be found can be the cell.
A Cell is the basic and smallest life’s unit which is responsible for all the life’s processes.
Cells are the functional, structural, and biological units of all living beings. A cell can also be independently replicated. Thus, the cells are called the building blocks of life.
Each cell contains a fluid known as cytoplasm, enclosed by a membrane. And also presents in the cytoplasm are several biomolecules such as nucleic acids, proteins, and lipids. Furthermore, the cellular structures known as cell organelles are suspended in the cytoplasm.
A cell structure is comprised of the individual components with specific functions important to carry out the processes of life. These components include cell membrane, cell wall, cytoplasm, nucleus, and also cell organelles.
There are many multiple choice questions on cell structure and function. Let us go through a few cell structures and function MCQs.
Importance of MCQs
In general, the Multiple Choice Questions (MCQs) are recognized as the most useful and widely applicable type of objective test elements. They could be used to measure the most important educational outcomes, such as understanding, knowledge, judgment, and problem solving.
By preparing these MCQs once after completing every topic, we can able to attempt the competitive exams like NEET easily and effectively.
Let us look at the MCQ on cell structure and function, including the cell structure and function MCQ with answers.
1. In the Given List, Which is the Simplest Amino Acid?
Glycine is the simplest amino acid. It contains a single hydrogen atom as its side chain. It is also a proteinogenic amino acid.
2. Animal Cells are Interconnected by _______
Desmosomes are the structure by which adjacent cells are attached and formed from the protein plagues in cell membranes linked by the filaments.
3. Polythene Chromosomes are Found because of _____?
Endomitosis is the replication or duplication of the chromosome in the absence of nuclear division or cell, resulting in numerous copies within each cell, which occurs in the Drosophila’s salivary glands.
4. The rRNA is Synthesized by _________
A nucleolus is the small dense spherical structure in the cell nucleus. So, the r-RNA is synthesized by Nucleolus.
5. Which of the Following is Known as Mitoplast?
