CHapter4. Tour of a cell

Question 1

prokaryotic cell

Answer 1

Lacks nucleoid
no membrane enclosed organelles
smaller, simpler

Question 2

Eukaryotic (animal cells)

Answer 2

Has a nucleus
has organelles suspended in liquid cytosol
larger, more complex

Question 3

Endomembrane systems includes

Answer 3

the ER, golgi Apparatus, lysosomes, and vesicles.

Question 4

Nucleus

Answer 4

control center of the cell

Question 5

Endoplasmic Reticulum:

Answer 5

main manufacturing facilities in a cell. Produces molecules, connected to nuclear envelope. Two types: Smooth and rough ER.

Question 6

smooth ER

Answer 6

Lacks Surface ribosomes, produces lipidS, SteroidS, and helps the liver cells detoxify circulating drugs.

Question 7

Rough ER

Answer 7

Makes more membrane, ribosomes that stud outside of the membrane. ribosomes dock here. Proteins are completed inside.

Question 8

Lysosomes

Answer 8

contain digestive enzymes and break down worn-out organelles.

Question 9

Golgi apparatus

Answer 9

Located in edomembrane system. work with ER, receives, refines, stores, and distribution chemical products of cell.e. Lysosomes (Bubbles of digestive enzymes surrounded by membranes)

Question 10

Mitochondria

Answer 10

Where ATP is made

Question 11

Chloroplast

Answer 11

In plant cells, where photosynthesis occurs

Question 12

DNA is bound to proteins. forming a complex known as

Answer 12

Chromatin

Question 13

A cell has the following molecules and structures: enzymes, DNA, ribosomes, plasma membrane, and mitochondria. It could be a cell from;

Answer 13

plant or animal

Question 14

If a toxin, such as bacterial toxin, destroys ribosomes, what cellular activity will be affected first?

Answer 14

protein synthesis

Question 15

Select the cell type that is not correctly matched with the type of predominate organelle it would need to perform its unique function:

Answer 15

All of the cells above are correctly matched with the predominant type of organelle they would need to perform their unique function

Question 16

You look into a microscope and view an unknown cell. What might you see that would tell you whether the cell is prokaryotic or eukaryotic?

Answer 16

a nucleus

Question 17

If you wanted to film the movement of chromosomes during cell division, the best choice for a microscope would be a

Answer 17

light microscope, because the specimen must be kept alive.
