Unit 1 Test Review

An organism made of only one cell is unicellular or multicellular?

Unicellular

Name three things that ALL cells (prokaryotic and eukaryotic) have.

1. Cell membrane 2. DNA (genetic material, genetic information) 3. Cytoplasm 4. Ribosomes (non-membrane bound organelles)

What is the smallest functional unit of all living organisms?

Cell

What are all living things (organisms) composed of?

Cells

Cells that have a nucleus are called prokaryotic or eukaryotic?

Cells that have a nucleus are called EUKARYOTIC. Eu means "YOU"!!

What type of cell has membrane-bound organelles and a nucleus?

Eukaryotic Eu means "YOU" or "TRUE"!!

True or False: A prokaryotic organism can be multicellular.

FALSE!! All prokaryotic organisms are unicellular.

True or False: A prokaryotic cell does not have genetic information.

False!! Prokaryotic cells have genetic information (as well as cytoplasm and a cell membrane); prokaryotic cells DO NOT HAVE A NUCLEUS!!! Pro means "NO"!!

True or False: Water is composed of cells.

False!! Water is not living and therefore is not composed of cells.

An organism made of more than one cell is unicellular or multicellular?

Multicellular

What is the name of the structure that stores genetic information (DNA) in eukaryotic cells?

Nucleus

All cells come from what?

Pre-existing cells (cells that are already there)

What type of cell DOES NOT have a nucleus?

Prokaryotic

What type of cell has no nucleus and no membrane-bound organelles?

Prokaryotic Pro means "NO"!!

What is the main difference between prokaryotic and eukaryotic cells?

Prokaryotic cells DO NOT HAVE A NUCLEUS while eukaryotic cells do.

What type of cell, prokaryotic or eukaryotic, has DNA floating freely in the cytoplasm?

Prokaryotic cells' DNA floats freely in the cytoplasm.

What type of cell is a bacteria cell? Prokaryotic or eukaryotic?

Prokaryotic, because they do not have a nucleus. Pro means "NO"!!

True or False: Eukaryotic organisms can be unicellular or multicellular.

TRUE!! Eukaryotic organisms can be unicellular (like an amoeba) or multicellular (like you).

What do bacteria, roses, and bunny rabbits all have in common?

They are all composed of one or more cells.

True or False: All organisms are composed of at least one cell.

True!! All organisms are composed of at least one cell.

True or False: Eukaryotic cells are usually larger and more complex than prokaryotic cells.

True!! Eukaryotic cells are usually larger and more complex than prokaryotic cells.

When observing a slice of cork under a microscope, Robert Hooke saw what looked like little rooms. Based on this information, Robert Hooke can assume that the cork is most likely ... a. a type of mineral b. a type of living organism c. from only an animal d. from a man-made material

b. a type of living organism; anytime a cell is observed under a microscope, the specimen is from a living organism
