12 Questions
What is a cell?
The basic unit of life and the simplest collection of matter that can live.
Give an example of a unicellular organism.
Bacteria
What is the difference between unicellular and multicellular organisms?
Unicellular organisms consist of a single cell, while multicellular organisms are made up of many specialized cells.
How do cells strengthen emergent properties?
By helping in the correlation between structure and function of a living organism.
What do cells sense and respond to?
Environmental fluctuations.
What are the two main evolutionary branches in Prokaryotes?
Bacteria and Archaea
What are the basic common features shared by all cells?
All cells are bounded by a membrane, have cytosol, contain chromosomes with DNA, and have ribosomes.
What is the main difference in how DNA is contained in Eukaryotic and Prokaryotic cells?
In Eukaryotic cells, DNA is enclosed by a membrane in the nucleus, while in Prokaryotic cells, DNA is centered in the nucleoid without a membrane.
Explain the origin of the terms Prokaryotes and Eukaryotes.
Prokaryotes come from 'Pro' meaning before, and 'Karyon' referring to the nucleus. Eukaryotes come from 'Eu' meaning true, and 'Karyon' also referring to the nucleus.
Describe the cytoplasm in Eukaryotic cells compared to Prokaryotic cells.
In Eukaryotic cells, the cytoplasm contains various membrane-bound organelles, while in Prokaryotic cells, the cytoplasm does not have membrane-bound organelles.
What is the typical size difference between bacterial cells and eukaryotic cells?
Bacterial cells are usually 1-10 µm in diameter, while eukaryotic cells range from 10-100 µm in diameter.
Which type of cell, Prokaryotic or Eukaryotic, has a true nucleus bounded by a membranous nuclear envelope?
Eukaryotic cells have a true nucleus bounded by a membranous nuclear envelope.
This quiz covers the basic concept of cells, the classification of organisms based on cell structure, and the importance of cells in living organisms. Learn about the structure-function correlation and emergent properties of cells.
