Bio Exam 2 Flashcards
(24 cards)
What is the main difference between prokaryotes and eukaryotes?
The main difference is that eukaryotes have a nucleus and membrane-bound organelles, while prokaryotes do not.
True or False: Prokaryotes are typically smaller and simpler in structure compared to eukaryotes.
True
Fill in the blank: Prokaryotes lack a __________.
Nucleus
Which domain do prokaryotes belong to?
Bacteria and Archaea
What are examples of eukaryotic organisms?
Plants, animals, fungi, and protists
True or False: Eukaryotic cells are generally larger and more complex than prokaryotic cells.
True
What is the function of the nucleus in eukaryotic cells?
It houses the cell’s DNA and controls gene expression.
Which type of cells have membrane-bound organelles like mitochondria and endoplasmic reticulum?
Eukaryotic cells
Fill in the blank: Eukaryotic cells have a __________ that separates the genetic material from the rest of the cell.
Nucleus
What are the two main types of prokaryotes?
Bacteria and Archaea
True or False: Prokaryotic cells lack membrane-bound organelles.
True
What is the function of ribosomes in both prokaryotic and eukaryotic cells?
They are responsible for protein synthesis.
Fill in the blank: Prokaryotes have a __________ that contains the genetic material.
Nucleoid
True or False: Prokaryotic cells have a cell wall made of peptidoglycan.
True
What is the role of the cell wall in prokaryotic cells?
It provides structural support and protection.
Fill in the blank: Eukaryotic cells have __________ that perform specific functions within the cell.
Organelles
True or False: Eukaryotic cells can be unicellular or multicellular.
True
What is the cytoskeleton responsible for in eukaryotic cells?
It helps maintain cell shape, facilitates cell movement, and aids in cell division.
Fill in the blank: Prokaryotic cells lack a __________ to compartmentalize cellular processes.
Nucleus
True or False: Eukaryotic cells have a more complex internal structure due to the presence of membrane-bound organelles.
True
What is the endosymbiotic theory in evolutionary biology?
It proposes that eukaryotic cells evolved from symbiotic relationships between prokaryotic cells.
Fill in the blank: Eukaryotic cells have a __________ that regulates the movement of substances into and out of the cell.
Cell membrane
True or False: Eukaryotic cells have a more complex process of cell division compared to prokaryotic cells.
True
What are examples of prokaryotic organisms?
Bacteria and Archaea
