Cell Structure and Function

Cells fall into two broad categories based on

• Size of cell, small vs. large

• Shape of cell, circular or square

• Where genetic information is

• Color of cell

Which of the following statements about the two categories of cells is correct

• Eukaryotic cells do not have a nucleus and are large

• Prokaryotic cells do not have a nucleus and are larger

• Prokaryotic cells are small but more complex with organelles

• Eukaryotic cells are larger and more complex with organelles

Bacteria are ______ cells

• Prokaryotic

• Eukaryotic

When bacteria get information from the environment it is called

• Transduction

• Transformation

• Conjugation

• None of the above

When bacteria get information from the a virus it is called

• Transduction

• Transformation

• Conjugation

• None of the above

When bacteria get information from the another bacteria it is called

• Transduction

• Transformation

• Conjugation

• None of the above

A ___ is an extra piece of genetic material found in bacterial cells that can be passed during conjugation

• Plasmid

• Chloroplast

• Ribosome

• Nucleoid

Which of the following best summarizes the endosymbiotic theory?

• A larger prokaryotic cells was engulfed by a smaller prokaryotic cell

• A smaller prokaryotic cell became stuck to another small prokaryotic cell

• A larger prokaryotic cell engulfed smaller prokaryotic cells that functioned inside the larger cell

• A series of smaller prokaryotic cells broke down larger prokaryotic cells and functioned inside

What evidence supports the endosymbiotic theory?

• Mitochondria and chloroplast have their own DNA

• Mitochondria and chloroplast can divide on their own

• Mitochondria and chloroplast have a double membrane system
