Examples of autotrophs are green plants, algae, bacteria, etc....
As the plant opens its leaf pores to take in carbon dioxide, some of the moisture in the leaf can escape.
Photosynthesis takes place in all plants that contain chlorophyll.
It is not just animals that – plants carry out respiration as well. Plants respire all the time because their cells need energy to stay alive, but plants can only photosynthesise when they are in the light.
6CO + 6H O = C H O + 6O The factors that effect the rate of photosynthisis are the amount of light, the amount of carbon-dioxide (CO ) and the temperature that can be used by the plant....
Photosynthesis is the procedure all plants go through to make food.
Stems also carry water and minerals up from the roots to the leaves to help with photosynthesis and take food back down to be stored and distributed to the plant as it has need.
This oxygen released by trees and other plants becomes a part of the air we breath, while the glucose is carried to the other parts of the plant as nourishment. This essential process is what will make of 95 percent of the mass in a tree, and photosynthesis by trees and other plants is what contributes nearly all the oxygen in the air we breathe.
Photosynthesis is the method that plants use to make their own food.
They found that elevated CO2 increased rates of net photosynthesis in about 85% of the reported studies, while reducing stomatal conductances and rates of transpiration in approximately 75% of the cases analyzed....
Photosynthesis does the opposite of respiration. Carbon dioxide is absorbed and oxygen is produced. In order to study respiration in green plants we must block out the light, because although green plants respire all the time they only photosynthesize in the light.
An example of this would be the leaves of a plant.
Photosynthesis consists of two connected sets of reactions....
Additionally, four out of five people around the world today rely on plants for primary health care.

Photosynthesis need light to work, so light therefore should speed up the rate of photosynthesis.
Plants make their own food thru the process of photosynthesis
A lamp will be shined on to the pondweed and the amount of bubbles released from the plant will be counted....
Free rate of photosynthesis Essays and Papers - …
You know that too much sunlight can damage your skin, fade colors in clothing and cause other problems. Therefore it shouldn't be surprising to find out that sunlight also causes chlorophyll molecules to break down. In fact, during the summer, green plants must continually create new chlorophyll to replace what has been destroyed. This creation, or synthesis, of chlorophyll requires not only sunlight but also warm temperatures, so you can see why fall's cooler weather encourages our trees' leaves to begin showing colors other than green.

We also have to be careful when studying green plants because in the light the green parts of these plants carry out photosynthesis as well as respiration.
Leaves are the most important organs of most vascular plants
All parts of the plant respire, the leaves, the stem, the roots and even the flowers. The parts above the soil get their oxygen directly from the air through pores. The pores in the leaves are called stomata (singular: stoma). The pores in the branches of trees are called lenticels.
How to Show Oxygen Is a By Product of Photosynthesis …
Photosynthesis is an important process that permits plants, including trees, to use their leaves to trap the sun's energy in the form of sugar. The leaves then store the resulting sugar in cells in the form of glucose for both immediate and later . Photosynthesis represents a beautifully wonderful chemical process in which six molecules of water from roots combine with six molecules of carbon dioxide from the air and creates one molecule of organic sugar.
Plant Energy Transformations-Photosynthesis - …
A) sunlight concentration B) temperature C) chlorophyll concentration D) carbon dioxide availability Effects of the variables and there concentrations: The amount of sunlight will decide the rate of photosynthesis as there will be a an increased rate of photosynthesis due to the increased availability of photons of light....
Chlorophyll is an important part of photosynthesis
There's another substance in many leaves known as carotene. Carotene is a kind of "chlorophyll helper." That's because carotene absorbs sunlight energy like chlorophyll, but instead of keeping that energy and conducting photosynthesis with it, it passes its energy on to chlorophyll which then uses that energy to perform photosynthesis. Carotene is known technically as an "accessory absorber." Carotene holds up much better under sunlight than chlorophyll, so often in the fall when chlorophyll disappears from leaves, carotene is left behind. Since carotene absorbs blue-green and blue light in sunlight, the light it reflects back to our eyes from leaves in which the chlorophyll has disappeared is
