What is the equation for photosynthesis

6CO2+ 6H2O----> C6H12O6+ 6 O2

1

What molecules enter the light dependent reaction

H2O-water
light

2

What molecules are produced in the light dependent reaction

NADPH
ATP
Oxygen

3

What molecules enter the light independent reactions

Carbon dioxide

4

What molecules are produced in the light independent reactions

Glucose

5

What is the name of the Cylic reaction that takes place after light reaction

Calvin cycle/ dark reaction

6

Where does the energy of food originally come from

The sun- plants use light energy to make food

7

Autotrophs are

Organisms that make their own food

8

What is an example of an autotroph

Plant

9

Heterotrophs are

Organisms that obtain energy from food they eat

10

Examples of heterotrophs are

Animals

11

What is one of the principal chemical compounds that living things used to store energy

ATP

12

How is ATP different from ADP

ATP has three phosphate groups and ADP has two phosphate groups

13

What are three factors that affect the rate at which photosynthesis occurs

Temperature – increases with temperature
Carbon dioxide – increases with increased in carbon dioxide concentration
Light energy – requires energy which is obtained from light

14

What is the ganum

Stack of thylakoids together

15

What is the Lemela

Stick like structure that connects the thylakoids together

16

Where is the site of photosynthesis

Chloroplasts

17

What is the stroma

The stroma is the liquid that sells the site of photosynthesis (chloroplast)

18

What occurs during cellular respiration

Plants break down sugars during cellular respiration for food for themselves

19

How does the overall reaction for photosynthesis compared to the overall reaction for cellular respiration

It is the reverse of the overall reaction for cellular respiration
Mirrored

20

What plant pigments are involved in photosynthesis

Chlorophyll a, chlorophyll B

21

The light reaction takes place in the

Thylakoids

22

Calvin cycle takes place in the

Stroma

23

Happens to watermelon kills in the light reactions

What are molecules are split to get electrons ions and oxygen gas

24

What to products of the light reactions are used up in the Calvin cycle

ATP and NADPH

25

What happens to carbon dioxide molecules in the Calvin cycle reactions

Carbon dioxide molecules are combined with each other and with the electrons from NADPH to form glucose

26

How can cells store sugar that is produced in photosynthesis

It is stored as starch

27

Define thylakoids

Small disc likes compartments composed of membranes that of the site of light dependent photosynthesis
