Lesson 7

Question 1

What are the three parts of the cell theory?

Answer 1

1. All living things are composed of cells.
2. Cells are the basic units of structure and function in all living things.
3. All cells come from preexisting cells.

Question 2

How would you be able to recognize a prokaryotic cell under a microscope?

Answer 2

They are simpler, smaller, and do not enclose their DNA in a nucleus.

Question 3

What cells enclose their DNA in a nucleus

Answer 3

Eukaryote

Question 4

What do all cells have in common

Answer 4

All cells have a membrane

Question 5

What kind of organisms are all considered prokaryotes

Answer 5

Bateria

Question 6

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

Answer 6

Eukaryotic cell

Question 7

What does a nucleus do

Answer 7

assembles and produces ribosomes.

Question 8

What is the relationship between the nucleus and cytoplasm?

Answer 8

The nucleus is contained 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

Vacuole

Question 12

What structure makes proteins and where are these made?

Answer 12

The structure is the Ribosomes and the Nucleus are where they are made.

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

Chloroplast and Mitochondria

Question 16

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

Answer 16

Chloroplast

Question 17

What is the function of the cell wall?

Answer 17

Support and protect the cell

Question 18

How is the cell wall different than the cell membrane?

Answer 18

Cell walls let water, oxygen, carbon dioxide, and other substance easily pass through them but cell membranes regulate what comes through

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

to regulate what enters and leaves and to protect and support the cell

Question 21

How do prokaryotes and eukaryotes differ? 2 main reasons. Compare and contrast.

Answer 21

Prokaryotes differ from Eukaryotes because they do not enclose their DNA information in nuclei and Prokaryotes do not have as many specialized cells. Prokaryotes and Eukaryotes are similar because both of the cells can contain ribosome, cell membranes, cell walls, and cytoplasm.

Question 22

What surrounds all prokaryotic and eukaryotic cells

Answer 22

Cell membrane

Question 23

Where are ribosomes made of

Answer 23

Nucleolus

Question 24

What makes rough ER easy to identify

Answer 24

they are covered in ribosomes

Question 25

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

Answer 25

Ribosomes

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

Vacuoles

Question 29

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

Answer 29

ribosomes
