Gas Exchange Flashcards
At day time, what takes place for gas exchanging?
Photosynthesis and respiration.
What does photosynthesis do at daytime? (What it takes in and out, and the item name)
Photosynthesis absorbs Carbon dioxide and releases oxygen.
What does respiration do at daytime? (What it takes in and out, and the item name)
Respiration absorbs oxygen and releases carbon dioxide.
What is the net uptake/release at daytime? And briefly explain why.
Net release is oxygen because the plant releases more oxygen then it’s consumed. Net uptake is carbon dioxide because the plants consumed more carbon dioxide then it’s released.
At night time, what takes place for gas exchanging?
Only respiration.
What does photosynthesis do at nighttime?
Photosynthesis is stopped at nighttime.
At nighttime, what does respiration do?
Respiration absorbs oxygen and releases carbon dioxide at nighttime.
What is the net uptake/release at nighttime? And briefly explain why.
Net uptake is oxygen because only respiration takes place. Net release is carbon dioxide because only respiration takes place.
Why does the gas exchanging in daytime happens?
Because the rate of photosynthesis is larger then the rate of respiration.
Comparing gas exchanging in animals (inhaled and exhaled air), provide information on it for oxygen, carbon dioxide, water vapour and temperature.
Oxygen is more when inhaled and less when exhaled. Carbon dioxide is less when inhaled and more in exhaled. Water vapour is variable when inhaled and saturated when exhaled. Temperature is lower when inhaled and warmer when exhaled.
