Respiration And Photosynthesis

Question 1

What is respiration

Answer 1

• Respiration is the process in which energy is released from the molecules of food which you eat

Question 2

Where does respiration occur

Answer 2

In the mitochondria

Question 3

Aerobic respiration

Answer 3

Involves oxygen and is more efficient as the food is broken down to release energy

Question 4

What is the equation for aerobic respiration

Answer 4

Glucose + oxygen —> carbon dioxide + water

Question 5

Anaerobic respiration

Answer 5

Does not involve oxygen and releases less energy than aerobic respiration

Question 6

What is the word equation for anaerobic respiration

Answer 6

Glucose—> lactic acid (+ energy)

Question 7

What is an oxygen debt

Answer 7

When the lactic acid builds up because there is not enough oxygen present in the blood supply to break it down

Question 8

What is fermentation

Answer 8

A type of anaerobic respiration which occurs in yeast and instead of producing lactic acid Yeats produces ethanol which is a type of alchohol

Question 9

What is the word equation for fermentation

Answer 9

Glucose —> ethanol+carbon dioxide (+ energy )

Question 10

What is a mineral deficiency

Answer 10

When a plant doesn’t have enough minerals for a healthy growth

Question 11

How do nitrates phosphates potassium and magnesium help with the plant

Answer 11

nitrates - healthy growth
phosphates - healthy roots
potassium - healthy leaves and flowers
magnesium - making chlorophyll

Question 12

What is photosynthesis

Answer 12

A process that produces glucose using sunlight

Question 13

Where in a plant does photosynthesis occur

Answer 13

In the chloroplasts

Question 14

What is the word equation for photosynthesis

Answer 14

Water + carbon dioxide + sunlight —> glucose + oxygen

Question 15

What is a producer

Answer 15

Any organism that can use photosynthesis to produce its own food , these are not just limited to plants but can include other organisms such as algae

Question 16

What can the rate of photosynthesis be affected by

Answer 16

Light intensity
Carbon dioxide concentration
Temperature

Question 17

What adaptations do leaves have for photosynthesis

Answer 17

They are thin to allow the most light through
• There is a lot of chlorophyll to absorb light
• They have a large surface area to absorb as much light as possible

Question 18

What 4 things are needed for photosynthesis

Answer 18

Sunlight
Chlorophyll
Water
Carbon dioxide

Question 19

What is the stomata

Answer 19

The leaf is covered in holes allowing carbon dioxide to diffuse into the leaf

Question 20

What make chloroplasts green

Answer 20

Chlorophyll

Question 21

Where does most energy in the earth come from

Answer 21

The sun

Question 22

What is the difference between respiration and breathing?

Answer 22

The difference between breathing and respiration is that breathing is the process of taking in oxygen and releases carbon dioxide while respiration is the process where the body breaks down the oxygen so that the cells in the body can use it to create energy.

Question 23

What is the chemical formula for glucose

Answer 23

C6H12O6

Question 24

What is the chemical equation for photosynthesis

Answer 24

6CO2 + 6H2O —>C6H12O6+ 6O2
carbon water glucose oxygen
dioxide
