Chapter 5

Question 1

A series of reactions triggered by the closing of the stomata to prevent water loss however decreases photosynthetic output

Answer 1

photrespiration

Question 2

How is the US CO2 output?

Answer 2

4% population, 25% output

Question 3

What is the equation for photosynthesis?

Answer 3

6CO2 + 6H20 + Sunlight ——–Glucose and O2

Question 4

what happens to the hydrogen bonds in water when it heats and cools?

Answer 4

Bonds break as heat is absorbed and reform when heat is released.

Question 5

What is the retention of heat in the atmosphere by CO2 and other gasses?

Answer 5

The greenhouse effect.

Question 6

Where do light reactions occur?

Answer 6

Thylakoids.

Question 7

What happens in the stroma?

Answer 7

Calvin Cycle

Question 8

WHat occurs in light reactions?

Answer 8

Lights hits pigments and splits WATER to make ATP and oxygen and NADPH

Question 9

What are the Spatial plants known as and what are examples?

Answer 9

C4 Corn and legumes

Question 10

WHere does the Calvin Cycle occur?

Answer 10

The stroma

Question 11

What process of the Calvin Cycle?

Answer 11

Carbon fixation (binds CO2 to RuBP to make 3PGA) Reduction (addign electron from NADPH - converts 3pga to g3p) Regeneration of RUBP to start overs. one of the G3Ps is broken off to make sugar

Question 12

What carries Hydrogen to the Calvin cycle?

Answer 12

NADPH

Question 13

WHat is the movement of water from the roots to the leaves of a plant powered by ecaporation of water at the leaves and the cohesive and adhesive properties of water?

Answer 13

Transpiration.

Question 14

What are the adaptations that help prevent photorespiration?

Answer 14

Spatial and temporal

Question 15

What are the stages of photosynthesis?

Answer 15

Light reactions, and the Calvin Cycle

Question 16

What happens in the Thylakoids?

Answer 16

Light reactions.

Question 17

How do bodies of water help the enviroment?

Answer 17

help maintain stable temperatures by ABSORBING heat,

Question 18

What are the most common type of plants

Answer 18

C3

Question 19

What are the function of pigments?

Answer 19

trap light energy to generate ATP

Question 20

What are the temporal plants knwon as?

Answer 20

CAM

Question 21

What plants have a really high photorespiration and what do they do when temps get high?

Answer 21

C3 Plants / close off their stomatas to allow oxygen buildup but shuts off photosynthesis.

Question 22

How is light measured?

Answer 22

Photon waves

Question 23

Where does photosynthesis occur?

Answer 23

The chloroplast

Question 24

What is the biogeochemical cycle?

Answer 24

the flow of chemicals throughout the ecosystem.
