Most plants largely uptake Carbon dioxide (CO{-2})and release oxygen during the day (photosynthesis) and uptake oxygen and release CO{-2} during the night (respiration). Some plants such as Peepal tree can uptake CO{-2} during the night as well because of their ability to perform a type of photosynthesis called Crassulacean Acid Metabolism (CAM).

However, it is not true that they release large amounts of oxygen during the night. CAM is one of the three types of photosynthesis pathways occurring commonly in plants; the other two being C3 and C4 pathways.

Of these, C3 is the most common among land plants. CAM occurs primarily in desert plants and epiphytes (plants that live on other plants, usually large trees). CAM plants do not open their stomata during the day in order to minimise water loss. During the night, they open their stomata and fix CO{-2} in the form of malate .

During the day, they breakdown the malate and use the released CO2 through Kalvin cycle to produce sugars, similar to C3 plants. However, CAM is an energy inefficient reaction and hence plants use CAM only during certain conditions.

Peepal tree is a hemi-epiphyte in its native habitat i.e. the seeds germinate and grow as an epiphyte on other trees and then when the host-tree dies, they establish on the soil. It has been suggested that when they live as epiphyte, they use CAM pathway to produce carbohydrates and when they live on soil, they switch to C3 type photosynthesis.

So, Peepal tree would either release or not release CO{-2} in the night depending on if they are epiphytic or not. For other CAM plants, it would depend on if they have adequate water or not, or other environmental factors.

Do trees reflect light or emit light?

It seems readily apparent that trees reflect light, since you don't see them glowing at night.

Why don't birds suffocate due to carbon dioxide near trees when they sleep at night?

Because, although the trees emit carbon dioxide during the night as part of their respiration function, the percentage of the carbon dioxide in the air never reaches a dangerous level, or even discomfort level. Let's not forget that the trees are in open air with sufficient oxygen always present, not in greenhouses or closed rooms.

If tree creates any pollution?

Trees create several types of pollution: * Pine trees and similar emit turpenes and related volatiles. This is the blue haze you see over coniferous forests * Trees release pollen, a potential allergen * Oak leaves and pine needles have tannins in their leaves/needles which can pollute water * Decomposing trees emit carbondioxide * When in a forest fire trees emit smoke and particulate * At night tree respiration releases carbon dioxide * Some trees have irritating saps

Importance of carbon?

Carbon is important to humans believe it or not...trees need carbon dioxide to survive and they emit oxygen which we need to survive...connect the dots

Do bacteria emit oxygen?

yes they do.

What gases will be taken in and given out by a green plant in the dark?

Carbon dioxide is taken in. Oxygen is given out

House plants increase oxygen in a home?

Yes, houseplants increase oxygen in the home, in the day time but at night they emit carbon dioxide, so you need to remove them at night, they used to remove plants in hospitals in the evening from patients bedsides. Most people just live with them as they do not emit a large amount of carbon dioxide. Depends how many plants you have.

Do trees emit carbon monoxide?

Trees do not produce carbon monoxide unless they are burnt.

How do the trees help the planet survive?

They work sort of like natural air-filters. They draw in carbon dioxide and emit oxygen for us to breathe. Without them we would die.

What is the green house effect and how does it relate to auto emiissions?

Our cars emit lots of harmful gases into our air. It traps in the sun's heat and causes the 'greenhouse' effect. We should plant more trees to absorb the harmful gases and emit fresh, clean O2 or Oxygen.

What happens at night during photosynethesis?

At night, since there is no sunlight present to drive photosynthesis, no oxygen is produced. But, instead, plants respire and emit carbon dioxide gas. 6H2O + sunlight + 6CO2 ----> C6H12O6 + 6O2 At night, this reaction is reversed (respiration).

What makes carbon dioxide a greenhouse gas?

plants and animals emit carbon dioxide. Actually our plants, ie trees, grasses... take in our(people, animals, pollution...) carbon dioxide and use it while converting it back into just oxygen, which they emit and we breathe. Its the CO2 cycle.

What are some things pandas do to help the earth?

They are a symbol to the Chinese, that is worthy protecting. So the forests were Pandas are breeding are made into national parks and the trees there emit oxygen while absorbing CO2.

Do plants produce carbon dioxide and use up oxygen?

During the day when there is ample sunlight they use carbon dioxide and produce oxygen by photosynthesis. At night and for their life processes (cellular respiration) they consume oxygen and emit carbon dioxide. Overall they produce more oxygen than carbon dioxide.

Does Money plant emit carbon dioxide during night?


Why trees are important?

Because, without them, we wouldn't have any oxygen. The sun causes the leaves to breathe in Carbon Dioxide that we emit, and in turn, it emits oxygen for us to use. Another answer: What stated above is true. Trees produce Oxygen, which is basically what we need to survive. Without trees, we wouldn't be able to breathe properly without Oxygen. More trees = more people living Trees also provide habitat for the world's most beautiful and mysterious creatures. They also provide us homes, firewood, boats, etc. Trees also make the plainest plain beautiful. Another Answer: Very basically: They absorb carbon dioxide and turn it to oxygen It takes 2 trees to supply enough oxygen for 1 person, and we need oxygen or we'll die They are the homes of many animals We can use them to make things such as furniture They look good :) They provide shade They are the food supply of many animals They can stop soil erosion They're TREES! :D

Can trees emit a bluish light pulsating throughout its branches?

No, but certain mosses and fungi can emit a low, steady light through bioluminescence. Under certain conditions, trees can gain a bluish glow from St. Elmo's Fire.

Which type of tree provides the most oxygen?

Oxygen is emitted as trees ad mass (wood or leaves) and create sugar for cell food. No tree has been identified as being more efficient than any other for this activity.The amount of oxygen generated by tree is dependant on the speed of its growth and the length of the growing season. As a consequence the youngest trees (saplings) are adding woody mass quickly and are producing oxygen at a high rate. Similarly the trees in tropical rain forests have a longer optimal period to grow and can emit oxygen for more days in a year.

How is carbon dioxide alive?

Its not. Carbon Dioxide is a gas that trees and plants ingest and we emit.

Describe the role that plants play in the oxygen carbon dioxide cycle?
