1. The term cell was given by _________.
A. Robert Hooke
B. Tatum
C. Schwann
D. De Bary
ANSWER: A.Robert Hooke
SOLUTION :The term cell was coined by Robert Hooke. Robert Hooke observed a honeycomb-like structure under the microscope while cutting a thin section of cork, hence he named the structure as a cell.
2. The membrane around the vacuole is known as _______.
A. Tonoplast
B. Elaioplast
C. Cytoplast
D. Amyloplast
ANSWER:A.Tonoplast
SOLUTION:The vacuoles are surrounded by a membrane called tonoplast and filled with cell sap. Also called the vacuolar membrane, the tonoplast is the cytoplasmic membrane surrounding a vacuole, separating the vacuolar contents from the cell’s cytoplasm.
3. Which one is a functional unit of a body?
A. Mitochondria
B. Cytoplasm
C. Spleen
D. Cell
ANSWER :D.Cell
SOLUTION:Cells are the basic structural and functional unit of all life. Examples include red blood cells and nerve cells.
4. Which one is used by cells to interact with other cells?
A. Cell tubules
B. Cell junctions
C. Cell adhesions
D. Cell detectors
ANSWER: B.Cell junctions
SOLUTION: The three main ways for cells to connect with each other are: gap junctions, tight junctions, and desmosomes. These types of junctions have different purposes, and are found in different places.
5. In which of the following type of cells Sarcoplasmic reticulum is found?
A. Muscle cells
B. Liver cells
C. Kidney cells
D. Neurons
ANSWER:A.Muscle cells
SOLUTION:The sarcoplasmic reticulum (SR) is a specialized form of the endoplasmic reticulum of muscle cells, dedicated to calcium ion (Ca2+) handling, necessary for muscle contraction and relaxation.
6. Which one is known as the powerhouse of a cell?
A. Mitochondria
B. Cytoplasm
C. Lysosome
D. Nuclei
ANSWER: A.Mitochondria
SOLUTION:Mitochondria are known as the powerhouse of cells. It is because the mitochondrion is the site of cellular respiration where energy in the form of ATP (Adenosine triphosphate) is generated as a result of oxidation of food constituents.
7. Which of the following is known as the suicide bag of a cell?
A. Mitochondria
B. Golgi Complex
C. Lysosome
D. Nuclei
ANSWER:C.Lysosome
SOLUTION : Lysosomes are called “suicide bags” of the cell because they have hydrolytic enzymes stored in them. These enzymes are used to digest complex molecules in a cell.
8. Lysosomes are produced by which cell organelles?
A. Mitochondria
B. Endosplasmic Reticulun
C. Golgi Complex
D. DNA
ANSWER: C.Golgi Complex
SOLUTION:Therefore, lysosomes are synthesized by Golgi bodies present in the cell.
9. Which cell doesn’t contain a cell wall?
A. Plant Cell
B. Bacteria
C. Fungi
D. Animal cell
ANSWER:D.Animal cell
SOLUTION: Animal cells lack cell walls. The cell wall is present in plant cells, bacteria, and fungi. In plants, the cell wall is the outermost part of the cell and is mainly involved in providing structural support, and rigidity and also protects the plant cell from the external environment.
10. DNA is stored in which of the following cell organelle?
A. Cell wall
B. Cell Membrane
C. Nucleus
D. Cytoplasm
ANSWER: C.Nucleus
SOLUTION:
Nucleus. Known as the cell’s “command center,” the nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid).
