Flashcards in Respiration Deck (24):
What do plants need energy for?
Plants need energy to grow, repair tissues, reproduce and to absorb nutrients
What is the difference between respiration in plants and respiration and respiration in animals?
Animals use glucose from the food they eat in respiration but plants make glucose by a process called photosynthesis
What is a reactant when it comes to respiration?
Glucose and oxygen reacting together to create an outcome
How could you get evidence to see if water is released out of animals?
You could breathe onto a cold surface such as a mirror or a window and you will see misting or droplets of water
How could you get evidence to see if water is released out of plants?
You could put a plastic bag on a plant
What is the equation for aerobic photosynthesis?
Carbon dioxide+water~~light energy~~glucose+oxygen
What is the equation for respiration?
Why is respiration and photosynthesis dependent on each other?
They both give each other what they need and produce what’s needed for the other etc.
What happens if not enough oxygen is supplied to the working muscles?
Then glucose cannot be broken down completely
What is the equation for anaerobic respiration?
What are the organisms the anaerobically respire?
Human muscles, different types of bacteria, yeast and fungi
What is the equation for when plants and yeast anaerobically respire?
How do plants respire?
The leaves aerobically respire and the root anaerobically respire
How can yeast cells survive?
By carrying out aerobic or anaerobic respiration
Both forms release carbon dioxide gas as a product
What does yeast produce?
Yeast produces ethanol (alcohol) as a by product
What is the process of respiration of yeast called?
This process is called fermentation
What are the uses of fermentation?
The uses of fermentation is to make beer, wine, bread, pickled cabbage, yoghurt and cheese
What is another word for anaerobic respiration?
What is respiration?
Respiration is the chemical process that releases the energy from food for our cells to use
What carries out respiration?
All cells carry out respiration (it is not the same as breathing)
Where does the glucose come from?
From food in the digestive system
Where does the oxygen come from?
From air in the lungs
What is done with the outcome of water?
Kept in the body or lost as sweat, urine or through breathing
