Respiration

Question 1

What do plants need energy for?

Answer 1

Plants need energy to grow, repair tissues, reproduce and to absorb nutrients

Question 2

What is the difference between respiration in plants and respiration and respiration in animals?

Answer 2

Animals use glucose from the food they eat in respiration but plants make glucose by a process called photosynthesis

Question 3

What is a reactant when it comes to respiration?

Answer 3

Glucose and oxygen reacting together to create an outcome

Question 4

How could you get evidence to see if water is released out of animals?

Answer 4

You could breathe onto a cold surface such as a mirror or a window and you will see misting or droplets of water

Question 5

How could you get evidence to see if water is released out of plants?

Answer 5

You could put a plastic bag on a plant

Question 6

What is the equation for aerobic photosynthesis?

Answer 6

Carbon dioxide+water~~light energy~~glucose+oxygen

Question 7

What is the equation for respiration?

Answer 7

Glucose+oxygen~~~~carbon dioxide+water(+energy)

Question 8

Why is respiration and photosynthesis dependent on each other?

Answer 8

They both give each other what they need and produce what’s needed for the other etc.

Question 9

What happens if not enough oxygen is supplied to the working muscles?

Answer 9

Then glucose cannot be broken down completely

Question 10

What is the equation for anaerobic respiration?

Answer 10

Glucose~~~~lactic acid(+energy)

Question 11

What are the organisms the anaerobically respire?

Answer 11

Human muscles, different types of bacteria, yeast and fungi

Question 12

What is the equation for when plants and yeast anaerobically respire?

Answer 12

Glucose~~~~ethanol+carbon dioxide+energy

Question 13

How do plants respire?

Answer 13

The leaves aerobically respire and the root anaerobically respire

Question 14

How can yeast cells survive?

Answer 14

By carrying out aerobic or anaerobic respiration

Both forms release carbon dioxide gas as a product

Question 15

What does yeast produce?

Answer 15

Yeast produces ethanol (alcohol) as a by product

Question 16

What is the process of respiration of yeast called?

Answer 16

This process is called fermentation

Question 17

What are the uses of fermentation?

Answer 17

The uses of fermentation is to make beer, wine, bread, pickled cabbage, yoghurt and cheese

Question 18

What is another word for anaerobic respiration?

Answer 18

Fermentation

Question 19

What is respiration?

Answer 19

Respiration is the chemical process that releases the energy from food for our cells to use

Question 20

What carries out respiration?

Answer 20

All cells carry out respiration (it is not the same as breathing)

Question 21

Where does the glucose come from?

Answer 21

From food in the digestive system

Question 22

Where does the oxygen come from?

Answer 22

From air in the lungs

Question 23

What is done with the outcome of water?

Answer 23

Kept in the body or lost as sweat, urine or through breathing

Question 24

What is done with the outcome of carbon dioxide?

Answer 24

Breathed out of the lungs
