Question 1

Photosynthesis

Answer 1

process by which cell captures energy in sunlight and uses it to make food

Question 2

What is the difference between an autotroph and heterotroph?

Answer 2

Autroph: an organism that makes its own food
Heterotroph: can’t make their own food

Question 3

What happens in the two stages of photosynthesis?

Answer 3

1st stage- captures suns energy through chloroplasts
2nd stage- uses energy to make its own food

Question 4

What is the photosynthesis equation?

Answer 4

Carbon dioxide + water = a sugar + oxygen

Question 5

What are the raw materials and products?

Answer 5

Raw - carbon dioxide, water
Products - oxygen, sugar

Question 6

Where does all the energy come from?

Answer 6

The sun

Question 7

What happens to the sugar in photosynthesis?

Answer 7

Plants use sugar to make food
Break down sugar molecules to release energy to carry out plant’s functions
It isStored

Question 8

Pigment

Answer 8

colored chemical compounds that absorb light

Question 9

Chlorophyll

Answer 9

pigments in chloroplasts

Question 10

Stomata

Answer 10

small opening on the underside of leaves

Question 11

What is respiration?

Answer 11

the process by which cells obtain energy from glucose

Question 12

What is the respiration equation?

Answer 12

Sugar + Oxygen = Carbon Dioxide + Water + energy

Question 13

What are the raw materials and products in cellular respiration

Answer 13

Raw - Sugar, Oxygen
Products - Carbon dioxide, water, energy

Question 14

What happens in each stage of respiration?

Answer 14

1st Stage
Sugar is broken down into smaller molecules
Oxygen is not involved
Small amount of energy is released
2nd Stage
Small molecules are broken down into smaller molecules
Oxygen is required
Large amount of oxygen is released

Question 15

Where does each stage take place?

Answer 15

1st Stage - Cytoplasm
2nd Stage - Mitochondria

Question 16

What is the opposite of respiration? Why?

Answer 16

Photosynthesis because the raw materials and products are switched to begin and to end

Question 17

What is fermentation

Answer 17

Oxygen not nescassary

Question 18

What happens on Earth if all the plants die?

Answer 18

We would die

Question 19

Where does water and carbon dioxide come from?

Answer 19

Water-roots when it rains
Carbon dioxide- Us when we breathe

Question 20

Name two things sugar is used for?

Answer 20

Food, and to release energy
