Week 4 INFO

Question 1

What is the study of how bodies work?

Answer 1

Physiology

Question 2

What is transpiration?

Answer 2

The loss of water through leaves due to evaporation

Question 3

What happens when stomata are open?

Answer 3

Gas exchange occurs (to get CO2) and transpiration.

Question 4

What is water cohesion and adhesion?

Answer 4

Cohesion: Water bonds to itself (or other water molecules)
Adhesion: Water bonds to other molecules

Question 5

What is the Transpiration-Cohesion Theory?

Answer 5

Water (and nutrients) are pulled from the roots to the xylem to get to the stomata in the leaves.

Question 6

What is the Pressure-Flow Hypothesis?

Answer 6

-Sugar actively loaded into the phloem
-Water passively flows in by osmosis
-Pressure builds, forcing sugar to flow to the sink
-Sugar actively unleaded at sink location

Question 7

What crops are valued for their sucrose?

Answer 7

Sugar beets and Sugar cane

Question 8

What are hydroponics?

Answer 8

A form of agriculture where plants are grown without soil and instead placed in water supplied with nutrients

Question 9

What are aeroponics?

Answer 9

A form of agriculture where plants are grown without soil and instead hung up and sprayed with water supplied with nutrients

Question 10

What do energy carrier molecules do?

Answer 10

They carry energy from one molecule to another

Question 11

What is the first law of thermodynamics?

Answer 11

Energy cannot be created or destroyed but it can change forms

Question 12

What is the most important energy molecule in the cell?

Answer 12

ATP (Adenosine Triphosphate)

Question 13

_______ ______ in energy
_______ ______ others energy

Answer 13

ADP, takes
ATP, gives

Question 14

What is the formula for photosynthesis?

Answer 14

CO2 + H2O –sunlight–> O2 + C6H12O6

Question 15

What occurs in the Thylakoid membrane?

Answer 15

chlorophyll molecules exist and sunlight is absorbed

Question 15

Where do the two stages of photosynthesis occur?

Answer 15

Light Reactions: Thylakoid Membranes
Calvin Cycle: Stroma

Question 16

What occurs during the light reaction phase?

Answer 16

Converts solar energy to chemical energy (ATP and NADPH)

Question 17

What are the properties of light?

Answer 17

Light can be absorbed, reflected, and transmitted

Question 18

What colors can be absorbed by plants?

Answer 18

Red and Blue wave lengths

Question 19

What is created as a waste product during the light reaction phase?

Answer 19

Oxygen

Question 20

What occurs during the Calvin Cycle?

Answer 20

The use of CO2 to build glucose molecules

Question 21

What is the formula for Cellular Respiration?

Answer 21

O2 + C6H12O6 —-> CO2 + H2O + ATP

Question 22

What occurs during cellular respiration?

Answer 22

The breakdown of glucose to produce ATP (energy)
