Flashcards in Chapter 5 Deck (24):
1

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

photrespiration

2

How is the US CO2 output?

4% population, 25% output

3

What is the equation for photosynthesis?

6CO2 + 6H20 + Sunlight --------Glucose and O2

4

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

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

5

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

The greenhouse effect.

6

Where do light reactions occur?

Thylakoids.

7

What happens in the stroma?

Calvin Cycle

8

WHat occurs in light reactions?

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

9

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

C4 Corn and legumes

10

WHere does the Calvin Cycle occur?

The stroma

11

What process of the Calvin Cycle?

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

12

What carries Hydrogen to the Calvin cycle?

NADPH

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?

Transpiration.

14

What are the adaptations that help prevent photorespiration?

Spatial and temporal

15

What are the stages of photosynthesis?

Light reactions, and the Calvin Cycle

16

What happens in the Thylakoids?

Light reactions.

17

How do bodies of water help the enviroment?

help maintain stable temperatures by ABSORBING heat,

18

What are the most common type of plants

C3

19

What are the function of pigments?

trap light energy to generate ATP

20

What are the temporal plants knwon as?

CAM

21

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

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

22

How is light measured?

Photon waves

23

Where does photosynthesis occur?

The chloroplast

24

What is the biogeochemical cycle?

the flow of chemicals throughout the ecosystem.
