Q1
Easy
Who is credited with the formulation of the cell theory?
A.
Schleiden and Schwann
B.
Virchow and Hooke
C.
Pasteur and Watson
D.
Darwin and Lamarck
Show Answer & Explanation
Correct Answer: A
Schleiden and Schwann are known for formulating the cell theory, which states that all living things are made of cells and that the cell is the basic unit of life.
Q2
Easy
Which statement is NOT part of the cell theory?
A.
All living organisms are composed of cells.
B.
Cells arise from pre-existing cells.
C.
Viruses are made of cells.
D.
The cell is the basic unit of life.
Show Answer & Explanation
Correct Answer: C
Viruses are not composed of cells; they are acellular and do not fit into the cell theory.
Q3
Easy
What did Rudolf Virchow contribute to cell theory?
A.
All living organisms are composed of cells.
B.
Cells are the basic unit of life.
C.
All cells come from pre-existing cells.
D.
Cells have various shapes and sizes.
Show Answer & Explanation
Correct Answer: C
Rudolf Virchow stated that all cells arise from pre-existing cells, which is a crucial part of cell theory.
Q4
Medium
Which of the following statements is NOT part of the cell theory?
A.
All living organisms are composed of one or more cells.
B.
Cells are the basic unit of life.
C.
All cells arise from pre-existing cells.
D.
Cells can arise from non-cellular matter.
Show Answer & Explanation
Correct Answer: D
The cell theory states that all living organisms are made of cells, and cells come from existing cells. The statement that 'cells can arise from non-cellular matter' contradicts this theory.
Q5
Medium
Which of the following scientists is credited for coining the term 'cell'?
A.
Robert Hooke
B.
Matthias Schleiden
C.
Theodor Schwann
D.
Louis Pasteur
Show Answer & Explanation
Correct Answer: A
Robert Hooke is known for first using the term 'cell' when he observed cork slices under a microscope, describing the small compartments he saw.
Q6
Medium
In which year did Schleiden and Schwann propose the cell theory?
A.
1838
B.
1850
C.
1801
D.
1865
Show Answer & Explanation
Correct Answer: A
The cell theory was proposed by Schleiden and Schwann in 1838, which established the foundation for modern biology.
Q7
Medium
Which of the following observations supports the cell theory?
A.
Viruses can replicate outside a host cell.
B.
All cells contain DNA.
C.
Bacteria can survive without any cells.
D.
Living organisms are not made of cells.
Show Answer & Explanation
Correct Answer: B
The observation that 'all cells contain DNA' supports the cell theory, as it emphasizes that all living organisms are made of cells and share fundamental molecular components.
Q8
Hard
Which of the following statements is NOT a part of the modern cell theory?
A.
All living organisms are composed of cells.
B.
Cells arise only from pre-existing cells.
C.
Cells are the basic unit of life.
D.
Cells can spontaneously generate from non-living matter.
Show Answer & Explanation
Correct Answer: D
The modern cell theory states that cells arise only from pre-existing cells, not from non-living matter. This refutes the concept of spontaneous generation.
Q9
Hard
The concept of 'Omnis cellula e cellula' emphasizes which aspect of cell theory?
A.
The importance of cell structure.
B.
The continuity of life through cell division.
C.
The similarity between plant and animal cells.
D.
The functions of organelles within cells.
Show Answer & Explanation
Correct Answer: B
'Omnis cellula e cellula' translates to 'all cells arise from cells,' emphasizing that new cells are formed through the division of existing cells, highlighting continuity in life.
Q10
Hard
How did the work of Schleiden and Schwann contribute to the development of cell theory?
A.
They discovered the nucleus in cells.
B.
They proposed that all plants and animals are made of cells.
C.
They formulated the concept of spontaneous generation.
D.
They identified the role of mitochondria in cells.
Show Answer & Explanation
Correct Answer: B
Schleiden and Schwann are credited with proposing that all living organisms, both plants and animals, are composed of cells, which is a foundational aspect of cell theory.
