Mitochondria

Question 4

What structure/organelle makes proteins?

Answer 4

Ribosomes

Question 5

What structure/organelle supports and protects a plant cell?

Answer 5

Cell wall

Question 6

What structure/organelle traps light energy for a plant(photosynthesis)?

Answer 6

Chloroplasts

Question 7

What structure/organelle is a gel-like substance inside the cell membrane?

Answer 7

Cytoplsm/cytosol

Question 8

What structure/organelle packages substances in cell?

Answer 8

Golgi body

Question 9

What structure/organelle stores food, water, or waste?

Answer 9

Vacuole

Question 10

What structure/organelle is larger in plant cells?

Answer 10

Vacuole

Question 11

These are found only in plant cells?

Answer 11

Cell wall and chloroplasts

Question 12

What structure/organelle is used to transport materials in the cell?

Answer 12

Endoplasmic reticulum(ER)

Question 13

What structure/organelle controls the passage of materials into and out of a cell?

Answer 13

Cell membrane

Question 14

Network of internal protein filaments that help maintain the internal organization and general shape of the cell. They also help move materials in the cell and for some cells the cell itself.

Answer 14

Cytoskeleton

Question 15

How many parts are there to the cell theory?

Answer 15

3

Question 16

What are the three parts of the cell theory?

Answer 16

1. Cells form from other cells
2. Cell is the basic unit of life
3. Cells are the function and organization in all living organisms

Question 17

Do most animal cells have the same basic structures?

Answer 17

Yes

Question 18

Do most plant cells have the same basic structures?

Answer 18

Yes

Question 19

What is used to support a plant cell?

Answer 19

Cell wall and large central vacuole.

Question 20

What organelle would muscle cells have more of to supply needed energy?

Answer 20

Mitochondria

Question 21

How is the labeling done by golgi bodies?

Answer 21

Marker proteins

Question 22

Name all the structures of a plant cell.

Answer 22

Cell membrane, cell wall, vacuole, golgi bodies, mitochondria, chloroplast, cytoskeleton, smooth endoplasmic reticulum, nucleus, rough endoplasmic reticulum, ribosomes.

Question 23

Name all the structures of a animal cell.

Answer 23

Cell membrane, nucleus, rough endoplasmic reticulum, ribosomes, smooth endoplasmic reticulum, cytoskeleton, mitochondria, vacuole, golgi bodies, lysosomes, centrioles, cilia.

Question 24

What organelles are found in animal cells but not in plant cells?

Answer 24

Lysosomes, centrioles, and cilia.

Question 25

What organelle would animals need to harness energy directly from the sun?

Answer 25

Chloroplasts

Question 26

Who is responsible for giving the cell its name? What was he looking at?

Answer 26

Robert Hooke, he was looking at cork.

Question 27

What is the cell membrane made out of?

Answer 27

Carbohydrates, glycoproteins, cholesterol, and proteins.

Question 28

Why is the cell membrane often referred to as a fluid mosaic model?

Answer 28

Because like the cell membrane letting things in and out of the cell a mosaic lets light in and out both ways too.

Question 29

What features make the membrane selectively permeable? Why is this feature important?

Answer 29

Passive and active transport. It is important because passive transport doesn't require the cell's energy, while active transport does.
