chapter 5

Question 1

what is the process of photosynthesis?

Answer 1

Plants use water and carbon dioxide to form glucose and oxygen

Question 2

what is cellulose

Answer 2

uses glucose(monomer) to make cellulose(polysaccharide) (cellulose is most of the cell wall)

Question 3

what are autotrophs

Answer 3

organisms that can get energy without eating other organisms

Question 4

what are photoautotrophs?

Answer 4

organisms that can make organic molecules out of light energy

Question 5

what is the chemical equation of photosynthesis?

Answer 5

6CO2 + 6H2O (sunlight->) C6H12O6 + 6O2

carbon dioxide + water -> sugar (carbohydrate) + oxygen

Question 6

what is carbon fixation?

Answer 6

when carbon turns into an organic, usable form (glucose)

Question 7

Chloroplast

Answer 7

Where photosynthesis takes place

Question 8

chlorophyll

Answer 8

light-absorbing, responsible for the green pigment and is important to photosynthesis

Question 9

Mesophyll

Answer 9

tissue in the leaf

Question 10

Stomata

Answer 10

pores that let in carbon dioxide and releases oxygen

Question 11

veins

Answer 11

is where the water is delivered to after being absorbed by the roots

Question 12

What is the dense fluid in the chloroplast called

Answer 12

Stroma

Question 13

what is the stack called?

Answer 13

grana

Question 14

what is space in between the stack called

Answer 14

thylakoid

Question 15

What is a reduction

Answer 15

the gain of electrons and hydrogen ions (h+)

Question 16

what is oxidation?

Answer 16

the loss of electrons and hydrogen ions (or the gain of oxygen)

Question 17

What is stage one of photosynthesis

Answer 17

light reaction; light energy is turned into chemical energy and O2 through the thylakoid membrane

water is split to make O2

Question 18

What is made when H ions are reduced in NADP+

Answer 18

NADPH

Question 19

What cycle is NADPH traveled to

Answer 19

The calvin cycle

Question 20

What is used to power the calvin cycle

Answer 20

Light reaction generates ATP which provides chemical energy for the calvin cycle

Question 21

What kind of energy does sunlight contain?

Answer 21

Electromagnetic energy / radiation

Question 22

What do Electromagnetic energy travel in?

Answer 22

waves

Question 23

The shorter the wave…

Answer 23

the greater the energy

Question 24

pigments…

Answer 24

are where light molecules are absorbed and are built into the thylakoid membrane

Question 25

different wave lengths could…

Answer 25

result in different color shown in the plant

Question 26

in the carbon cycle, what do photosynthesis and cellular respiration share?

Answer 26

products and reactants (formula reversed)
