Yes, houseplants give off carbon dioxide during darkness and when dormant.
Houseplants, and any green plant, absorb carbon di-oxide (Co2) and produce oxygen in the process of photosynthesis.
During the day they absorb more then they produce and produce oxygen but during the night they give off carbon dioxide.
Some people believe this is why all flowers are removed from bed sides in hospitals during the night.
This is of course ridiculous. People in the hospital produce more CO2 than plants could possible produce. Also if this were true we would have to wear oxygen masks at night since no photosynthesis happens after dark.
What else can I help you with?
Do we give off carbon dioxide?
Only if you are breathing.
Do eucalyptus trees give off Carbon Dioxide?
Yes, eucalyptus trees undergo the process of photosynthesis where they absorb carbon dioxide and release oxygen. So, in general, eucalyptus trees do not give off carbon dioxide.
Does alcoholic fermentation give off carbon dioxide?
Yes
During cellular respiration what do organisms give off?
Carbon dioxide.
What does plant gives out?
Plant cells can give off oxygen when photosynthesis occurs. They give out carbon dioxide when they respire when there is no light available.
How do monkeys give off carbon dioxide?
Monkeys give off carbon dioxide when they exhale - the same as humans do!
What gas does yeast give off?
It gives off carbon dioxide which proves that it respires.
What is it that Plants and animals take in and then give off?
Plants take in carbon dioxide and give off oxygen through the process of photosynthesis. Animals take in oxygen and give off carbon dioxide through the process of respiration. This exchange of gases is essential for the survival of both plants and animals.
What does a car give off?
carbon dioxide
What do animals give off?
Carbon dioxide
Do muscles give off carbon dioxide?
no.
Why is it important that plants give off carbon dioxide?
I think you have it backwards. Plants actually absorb carbon dioxide and give off oxygen. It's obvious why it's important they give off oxygen.
What gas do Alka Seltzer tablets give off?
They give off carbon dioxide.
In total darkness does a plant give off carbon dioxide?
A plant does give off Carbon Dioxide at night when there is not enough light for photosynthesis to occur.
Do cells use carbon dioxide?
No. Animal cells use Oxygen and give off carbon dioxide as a waste product. Plant cells use carbon dioxide and give off oxygen.
Do worms give off carbon dioxide?
yes
What do dolphins give off into the air?
carbon dioxide
