Ribosomes create protein.

Question 10

What substance is inside the vacuole?

Answer 10

Vacuoles contain a cell sap, containing salts and sugar.

Question 11

What is the purpose of the cell wall?

Answer 11

The cell wall gives a plant shape and structure.

Question 12

What are bacterial cells called?

Answer 12

Prokaryotic.

Question 13

What are inside bacteria cells?

Answer 13

Bacteria cells contain, a cell membrane, cell wall, cytoplasm, and plasmids.

Question 14

Since a bacterial cell has no ‘true’ nucleus., where does it keep it’s genetic material?

Answer 14

Inside the cytoplasm, in the form of plasmids, which are used in binary fission.

Question 15

What does the term turgid mean in reference to plant cells?

Answer 15

It means that the cell is has a high water content.

Question 16

What does the term flaccid mean in reference to plant cells?

Answer 16

It means the cell has a lower water content.

Question 17

What occurs in chloroplasts?

Answer 17

Photosynthesis.

Question 18

What kind of cells do the term ‘eukaryotic’ refer to?

Answer 18

Animal/Plant cells.

Not bacterial.

What substance do chloroplasts contain?

Answer 19

Chlorophyll.

Question 20

Name two places where stem cells are found.

Answer 20

Bone marrow and embryos.

Question 21

How can stem cells be used to help sick patients?

Answer 21

Stem cells can be used to create new nerve cells for paralyzed patients, and create insulin-producing cells for people with diabetes.

Question 22

What does the term ‘Active transport’ refer to?

Answer 22

Active transport refers to how sometimes substances are absorbed against a concentration gradient.

Question 23

Name a cell that take in substances through active transport.

Answer 23

A root hair cell.

Question 24

What is Osmosis?

Answer 24

How water moves across cells - from an area of high concentration to low concentration.
