Cell Theory Quiz

Who is credited with the discovery of cells?

• Isaac Newton

• Marie Curie

• Robert Hooke

• Galileo Galilei

What is the basic unit of life according to cell theory?

• organism

• molecule

• cell

• atom

What are the three main principles of cell theory?

• All living organisms are composed of one or more cells, the cell is the basic unit of structure and organization in organisms, and cells arise from pre-existing cells.

• Cells are only found in animals, cells can spontaneously generate from non-living matter, cells do not have genetic material

What is the function of the cell membrane?

• Controls the movement of substances in and out of the cell.

• Regulates cell division

• Stores genetic information

• Provides structural support to the cell

What is the role of the nucleus in a cell?

• Storage of nutrients in the cell

• Control center of the cell, containing DNA and regulating gene expression.

• Production of energy through photosynthesis

• Regulation of cell shape and movement

What is the function of mitochondria in a cell?

• Stores genetic material

• Regulates cell division

• Synthesizes proteins

• Produces energy (ATP) through cellular respiration

What is the endosymbiotic theory?

• The endosymbiotic theory suggests that eukaryotic cells evolved from viruses.

• The endosymbiotic theory proposes that eukaryotic cells evolved from symbiotic relationships between different types of prokaryotic cells.

• The endosymbiotic theory claims that prokaryotic cells evolved from eukaryotic cells.

• The endosymbiotic theory proposes that all cells originated from a single primordial cell.

What is the difference between prokaryotic and eukaryotic cells?

• Number of chromosomes

• Presence of a cell wall

• Nucleus and membrane-bound organelles

• Size of the cell

What is the importance of cell theory in biology?

• Cell theory is important in biology because it explains the basic structure and function of living organisms.

• Cell theory is important in biology because it studies the weather patterns of living organisms.

• Cell theory is important in biology because it explains the behavior of subatomic particles.

• Cell theory is important in biology because it predicts the stock market trends.

How has our understanding of cells evolved since the discovery of cell theory?

• The understanding of cells has remained stagnant since the discovery of cell theory

• Cell theory has been disproven, leading to confusion about cell structure and function

• Advancements in technology have hindered our understanding of cells rather than enhancing it

• Advancements in technology such as microscopy, biochemistry, and molecular biology have allowed us to gain more knowledge about cell structure, function, and interactions with other cells.
