Question 5

What kind of organisms are all considered prokaryotes?

Answer 5

Bacteria

Question 6

If you look at a cell and it has a large membranous structure with a very dense dark spot in it, what do you know about this cell?

Answer 6

That it is a eukaryotic cell with DNA stored in the nucleus

Question 7

What does the nucleus do?

Answer 7

Contains and stores the DNA

Question 8

What is the relationship between the nucleus and the cytoplasm?

Answer 8

The nucleus is suspended in the cytoplasm

Question 9

The nucleus is the site for what production?

Answer 9

Ribosomes

Question 10

What organelle breaks down other organelles and other cells?

Answer 10

Lysosomes

Question 11

What organelle stores salts and water?

Answer 11

vacuoles

Question 12

What structure makes proteins and where are these made?

Answer 12

Ribosomes; they are made in the nucleolus

Question 13

What organelle modifies and sorts proteins?

Answer 13

Golgi apparatus

Question 14

What organelle converts chemical energy in food to compounds that the cell can use to make energy?

Answer 14

Mitochondria

Question 15

Which two organelles are involved in energy conversion?

Answer 15

Mitochondria and chloroplasts

Question 16

What organelle is specific to plant cells but never animal cells?

Answer 16

Chloroplasts

Question 17

What is the function of the cell wall?

Answer 17

They support and protect the cell and allow for needed substances to pass through easily

Question 18

How is the cell wall different than the cell membrane?

Question 19

What never has a cell wall?

Answer 19

Animal cells

Question 20

What is the primary function of the cell membrane?

Answer 20

It regulates what enters and leaves the cell and supports and protects the cell

Question 21

What are the pumps and channels of the cell membrane made of?

Answer 21

Globular proteins

Question 22

What surrounds all prokaryotic and eukaryotic cells?

Answer 22

Cell membrane

Question 23

Where are the ribosomes made?

Answer 23

Nucleolus

Question 24

What makes the rough ER easy to identify?

Answer 24

Flattened sacs and elongated canals

Question 25

Where are protein synthesizers made and where are most of them located?

Answer 25

ribosomes and most of them are located in muscle tissue

Question 26

What is the most dense area of the cell?

Answer 26

Nucleolus

Question 27

Where is the cell’s genetic information found?

Answer 27

Chromatin

Question 28

What is the largest structure in a plant cell?

Answer 28

Central Vacuole

Question 29

If a cell needs a lot of protein molecules what do they need a lot of?

Answer 29

Ribosomes

Question 30

How do Prokaryotes and Eukaryotes differ. 2 main reasons. Compare and contrast.

Answer 30

Prokaryotes do not enclose their DNA information in a nuclei whereas eukaryotes enclose their DNA information in a nuclei. Prokaryotes are generally smaller and simpler whereas eukaryotes are generally larger and more complex.
