General Photosynthesis

Question 1

What is Photosynthesis?

Answer 1

Process of capturing energy from sun, and using it to make chemical energy

Question 2

What is the General Chemical Equation for Photosynthesis?

Answer 2

6CO2 + 6H2O → C6H12O2 + 6O2

Question 3

How would you say the Chemical Equation in words?

Answer 3

Carbon Dioxide + Water → Glucose + Oxygen

Question 4

What are Packets of Light Energy called?

Answer 4

Photons

Question 5

Why are Plants Green?

Answer 5

Because Chlorophyll A and B absorb Red and Blue light but reflect Green

Question 6

Why do Plants change color in the Fall?

Answer 6

Chlorophyll gets Denatured

Question 7

Absorbing light =

Answer 7

Absorbing Energy

Question 8

What does Absorbing Light do to the Chlorophyll?

Answer 8

It causes electrons to be excited

Question 9

What is the main Organ that carries on Photosynthesis?

Answer 9

The Leaf

Question 10

What is a Stoma?

Answer 10

Opening that allows air to enter and leave leaf

Question 11

Why are Stoma closed during night?

Answer 11

To prevent water loss

Question 12

What is the Organelle where Photosynthesis occurs?

Answer 12

Chloroplast

Question 13

What is a Thylakoid?

Answer 13

A membrane bound sac

Question 14

What is a Granum/Grana?

Answer 14

A stack of Thylakoids

Question 15

What is a Stroma?

Answer 15

Fluid outside Thylakoids

Question 16

What is the Thylakoid Space?

Answer 16

Space inside Thylakoid

Question 17

What is the difference between Stroma and Stoma?

Answer 17

Stroma = Thylakoid Fluid
Stoma = Hole for air

Question 18

What are the two parts of Photosynthesis?

Answer 18

Light Dependent Reaction and Light Independent Reaction

Question 19

Where do Light Dependent Reactions occur?

Answer 19

In the Thylakoid Membrane

Question 20

LIR and LDR are the two processes of…

Answer 20

Photosynthesis

Question 21

Which process comes first, LIR or LDR?

Answer 21

LDR

Question 22

What is Photorespiration?

Answer 22

It is a dysfunctional form of Photosynthesis

Question 23

What makes Photorespiration different from Photosynthesis?

Answer 23

Instead of using CO2, it uses O2, which produces only 1 PGA

Question 24

What are C3 Plants?

Answer 24

These are normal plants that convert carbon through the LIR

Question 25

What are C4 Plants?

Answer 25

These are plants that convert CO2 into 4-Cs (CCCC)

Question 26

What makes C4 Plants unique?

Answer 26

They have their stomates partially closed during the day and only lose 1/2 of water; typically these plants grow faster

Question 27

What are CAM plants?

Answer 27

Plants that close stomate during day and open during night; store things for Calvin Cycle during the night, and do the Calvin Cycle during the day; these plants grow slowly but lose less water, and hence have chunky leaves

Question 28

Sunlight is ______ energy

Answer 28

Radiant

Question 29

What are carotenoids?

Answer 29

Red and Orange colored Pigments

Question 30

What is chlorophyll?

Answer 30

Green/Blue pigments

Question 31

Why do leaves change colour in the fall?

Answer 31

Chlorophyll dies, and carotenoids take over

Question 32

What is the job of the Guard Cell?

Answer 32

To control the opening and closing of the Stomas
