Photosynthesis

Question 1

What is the photosynthesis equation?

Answer 1

H20+co2+soil—-light energy———C6H12O6+O2

Question 2

What is photosynthesis?

Answer 2

Is the process by which plants use sunlight water and carbon dioxide to create oxygen and energy in the form of sugar

Question 3

What is the key to photosynthesis?

Answer 3

Chlorophyll

Question 4

How does chlorophyll work in plants?

Answer 4

This large and complex molecule has electrons that become activated when light shines on it

Question 5

What are the different forms energy exists?,

Answer 5

Heat, light, electrical, chemical, and mechanical energy

Question 6

What activates the electrons in the chlorophyll?

Answer 6

The electrons in the chlorophyll are activated by light, and this electron energy is used to make organic molecules (new plant tissue)

Question 7

First law of thermodynamics?

Answer 7

The amount of energy does not change, only the forms of energy changes

Question 8

Second law of thermodynamics

Answer 8

Heat is always produced whenever one forms of energy is changed into another form

Question 9

A mother deffenition for photosynthesis?

Answer 9

Photosynthesis is the transformation of light energy into chemical energy.

Question 10

How is the energy of plants first converted?

Answer 10

Energy of sun is first converted into the chemical energy of plants.

Question 11

How many units of sun does photosynthesis require?

Answer 11

Photosynthesis requires about 100 units of sun energy to produce one unit of sugar energy.

Question 12

How do you call animals that eat plants?

Answer 12

Herbivores

Question 13

How do you call the animals that eat herbivores?

Answer 13

First carnivore

Question 14

How do you call the animal that eats first carnivore animals?

Answer 14

Second carnivore

Question 15

What is the energy conversion efficiency?

Answer 15

10%

Question 16

Where does carbon come from?

Answer 16

It comes from the air

Question 17

Where does the hydrogen and glucose come from

Answer 17

Plants make sugar by using energy from sunlight to transform carbon dioxide a gas absorbed from the air, and water taken from the ground by roots

Question 18

What do all multicellular, and unicellular plants have?

Answer 18

Chloroplast

Question 19

What does chloroplast contain?

Answer 19

Chloroplast contain chlorophyll and enzymes for the photosynthesis process

Question 20

What does chlorophyll contain?

Answer 20

The chloroplast has many specialized structures. Stacks of discs, called grana, contain the chlorophyll and act like photoelectric cells.

Question 21

What is the first stage of photosynthesis?

Answer 21

When light shines on these grana, the electrons of the chlorophyll are activated. This is the first step of photosynthesis

Question 22

What is the second step of photosynthesis?

Answer 22

Involves the building of sugar molecules from carbon dioxide and water.

Question 23

When light shines on chlorophyll, the light energy is transformed into….

Answer 23

Chemical energy

Question 24

How do scientist call the light reactions of photosynthesis?

Answer 24

Dark reactions

Question 25

How do scientist call the synthesis reactions?

Answer 25

Light-dependent reactions

Question 26

Wha kind of energy is required to run synthesis reactions?

Answer 26

Heat and light energy

Question 27

Where does that energy come from?

Answer 27

The sun

Question 28

What the name of the scale of short and long waves?

Answer 28

Electromagnetic spectrum

Question 29

How does energy exist?

Answer 29

Energy exists as waves

Question 30

Which waves have more energy

Answer 30

Short waves

Question 31

Which waves have less energy

Answer 31

Long waves

Question 32

How do you call waves shorter than violet light

Answer 32

Ultra violet

Question 33

How do you call waves longer than red lights

Answer 33

Infra red

Question 34

What is a visible light spectrum

Answer 34

Rainbows

Question 35

Which color is the short side of the rainbow?

Answer 35

Blue

Question 36

Which color is on the long side?

Answer 36

Red

Question 37

Which color is about in the middle?

Answer 37

Yellow

Question 38

Which color do you see when you look at plants?

Answer 38

Red

Question 39

Which two primary colors do you not see when looking at a plant?

Answer 39

Yellow and blue

Question 40

What takes energy

Answer 40

Electrons

Question 41

When light activates the electrons of chlorophyll, then those electrons have

Answer 41

Less energy

Question 42

What happens to chlorophyll solution when light is shined on it?

Answer 42

The chloroplast turned red

Question 43

Where are heavy large substances

Answer 43

At the bottom

Question 44

Where are light substances?

Answer 44

At the top

Question 45

What is chromotagraphy?

Answer 45

Is a very basic chemical process used to separate organic molecules from each other

Question 46

What happens during the process of chromotagraphy?

Answer 46

During this process a solvent passes through a sample that has be3n impregnated on a piece of paper
