Do leaf trees or evergreens produce more oxygen ?

Well, first of all you should rephrase your question "Do decidious or evergreen trees produce more oxygen (since evergreens have leaves).\n\nIn general, decidious trees do produce more oxygen.  A lot of this has to do with them living in warmer climates where they are more productive (eventhough they loose their leaves seasonally).  But evergreens do produce oxygen almost year-round (less is colder seasons).\n\nIt is important to note that trees use most of the oxygen they produce.

Plants take in oxygen, carbon dioxide and water, and produce sugar which contains carbon, oxygen and hydrogen atoms from all three. So they use more water than they put out. In fact, I don't believe they "exhale" water the way we do at all,

Plants.\n\nThey breathe in CO2 and breathe out Oxygen

if a plant is in a windy area, evaporation happens faster. Or in not too bright of sun, photosynthesis happens faster.  Also, if it's well watered, the roots suck more in and push it through the plant.  \n\nThis probably won't help at all, since I have no idea of what you're really talking about, but someone once told me that they liked nothing more than attempted BS.

What a silly question. In some plants all of those structures except the leaf can respire anaerobically.

Leaves have sugars, phytochemicals, and chlorophyll. The chlorophyll's color masks everything else, until the tree stops producing in the fall. Then the other compounds can shine. Different trees have different amounts of these "background" compounds, which are also influenced by sunlight and temperature; that's why the cold clear days in the northeast US help the trees give a good show.

Depends upon the tree and the conditions.  Pussie willow shoots (especially green ones) can be placed in a container of water and will actually grow roots.  These can be planted in the ground to form new trees or bushes.  Weeping willows do the same.\nExperiments have been done with whole evergreens to determine the amount of transpiration (of water vapor) from their needles (the trunk of the tree being placed in an aqueous solution of dilute minerals).  Based upon the oxygen gas generated if the tree is in sunlight), the tree does continue to live for some time.

Plants are living things, and like us, need noses to breathe.  The 'noses' of plants are tiny holes called stomata (s), stoma (p) at the underside of leaves.  These stoma help the plant exchange gases with its surrounding.  Oxygen is produced during the day as the byproduct of photosynthesis, when the plant takes in carbon dioxide in the presence of sunlight to make food.  At night, the plant rests and does not make any more food, thus consuming oxygen.  This whole process is called respiration.

you get more air from the trees, it takes away carbon dioxide, and it protects the ozone from further damage.

Your question is flawed some conifers are deciduous i.e larch, dawn redwood, ginko, bald cypress.  Your question should either be... What is difference between evergreens and deciduous plants? or What is the difference between gymnosperms and angiosperms?

B.\n\nCellular respiration uses Oxygen and releases CO2, and at Nighttime, Photosynthesis cannot occur(since there is a lack of light) and therefore cannot convert CO2 to O2, hence lowering the concentration

Well if I remember this right...NASA was doing experiments a few years ago with rhubarb and pumpkin plants. The C02 oxygen exchange was the greatest. Also there was something about a genetically engineered algae they were trying out

Fir trees. Their more expensive but it's really worth because it lasts longer.

Depends on the plant. Some plants grow faster than others.

Well, this happened once before.  Originally the earth had a very low concentration of atmospheric oxygen and oxygen was toxic to most organisms (they were all single celled back then).  But as organisms started to develop photosynthesis, oxygen was released into the atmosphere in huge amounts causing a massive extinction.  Now most organisms need or tolerate oxygen.  I'm not sure what would happen if the %O2 was increased now......I bet that plants wouldn't like it though.

The leaves channel the water to the area at the edge of the leaves...this is where the most efficent water absorbing roots are, so they are getting more water by providing "shelter"....;

Photosynthesis produces oxygen by combining CO2 and H2O to make glucose and O2. Cellular respiration (what plants do at night and what animals do) takes glucose and O2 and makes CO2 and H20. The answer is C.
