Cards

Term
What does "eukaryote" mean literally
Definition
"true nucleus"  Becuase it has a true, membrane-bound nucleus with chromosomes.
Term
Name some eukaryotes
Definition
Animals, plants, fungi, protists
Term
What type of membrane do eukaryotes have?
Definition

Plasma membranes.

 

*note: prokaryotes also have plasma membranes.

 

Eukaryotic membranes have sterols in them to stabilize them.

 

 

Term
Can a eukaryote have a cell wall?
Definition

Yes, if it is a fungi, plant, or protist.

 

Note, however, that these cell walls may differ from one another AND from prokaryotic cell walls.

Term

Do eukaryotes have organelles?

 

What are organelles?

Definition

Yes. 

 

Organelles are sub-cellular structures which perform the cell's basic functions.

Term
What is the function of the nucleus?
Definition

Stores cell's genome

 

(blueprint)

Term
What are the ribosomes consist of and what do they do?
Definition

Consist of proteins and RNA.

 

Synthesizes proteins on the ribosomes.

 

(Machines for production of protein)

 

 

Term

What does the smooth and rough endoplasmic reticulum do?

 

Why is rough endoplasmic reticulum rough?

Definition

Smooth ER produces lipids. Rough produces proteins.

 

Rough ER is studded with ribosomes.

 

 

 

(Production line)

Term
What does the Golgi Apparatus do?
Definition

Packages the products of the endoplasmic reticulum for export to rest of cell.

 

(Mail room)

Term

What happens at the mitochondria?

 

Do mitochondria have their own DNA?

Definition

Catabolism.

 

Yes.

 

(Energy source)

Term
What happens at the chloroplasts?
Definition

photosynthesis

 

(energy source)

Term

What are lysosomes?

 

Do they have their own DNA?

Definition

Membrane bags of digestive enzymes.

 

Yes.

 

(custodian/security guard)
Term

What are flagella used for?

 

Are eukaryotic and prokaryotic flagella the same?

Definition

Movement.

 

No.  They look the same but differ in composition.

 

Term
What are cilia used for?
Definition
Movement, or to move a substance over the cell surface.
Term
What is the purpose of capsules and what are they made of?
Definition

Capsules are used for:

  • adherence
  • protection from phagocytosis

 

Capsules are made of carbohydrates.
