Why leaves have green color?
Leaves are green because they contain a green-coloured pigment called chlorophyll. Chlorophyll allows the leaves to capture sunlight and change it from light energy to chemical energy during photosynthesis.
How do plants have photosynthesis?
Photosynthesis is the change of light energy into chemical energy. Plants use the sunlight, the soil, the water to make a substance known as chlorophyll (this keeps leaves green). This is like the plant's food.
What role does chloroplasts and chlorophyll play in photosynthesis?
the chlorophyll is found in the thylakoid membrane. chlorophyll is the pigment that absorbs in red and blue and reflects green, which makes plants look green. chlorophyll captures the sun's energy and is used as energy to complete thephotosynthesis process (light dependent reaction.)
Why in Florida does leaves not change color?
its colder in New England than it is in Florida, the colder it gets it stops the process of photosynthesis and the chlorophyll looses its green pigment!
Why do plants need chlorophyll in photosynthesis?
Plants contain chlorophyll within their thylakoids, which are found within the chloroplasts. Chlorophylls are pigmented light capturing devices that are stacked closely together. They act like solar gathering antenna.
How do you do photosynthesis?
People cannot perform photosynthesis, in Autumn when tree leaves change colors that is what photosynthesis is. In Autumn, the chlorophyll pigments break down and reveal the presence of accessory pigments.
How tree with red leaves get food?
in green plants chlorophyll traps sunlight ,by which photosynthesis takes place.but in red leaves there is a pigment act as chlorophyll or pigment which cause change in colour.
What Does chlorophyll not absorb?
Chlorophyll does not absorb the color green. For this reason, the leaves of many plants appear green, as most other colours of light are absorbed (and therefore, are not reflected, and cannot be seen). When a plant dies, its leaves usually change colour, as the chlorophyll is no longer absorbing light.

What role do plant pigments play in the process of photosynthesis?
Pigments are able to absorb specific wavelengths of light which power photosynthesis. Chlorophyll, which is green, absorbs all wavelengths except green. Each photon excites an electron in the light harvesting complexes of a photosystem in a chlorophyll molecule, eventually producing ATPs. Other pigments will be a different color and will be able to absorb other wavelengths, maximizing energy absorbency when the sun's rays change.

When leaves change color are they still performing photosynthesis?
While there are leaves that perform photosynthesis and are not green in color, when the leaves of any deciduous plant change color it is part of a process in which decreasing sunlight triggers a decrease in chlorophyll levels as the plant transitions into dormancy for the winter. As such the leaves perform steadily less and less photosynthesis as they change color, finally stopping entirely after they detach from the plant.

What happens to chlorophyll when temperatures drop?
Plants stop producing chlorophyll when the temperature drops, because there is less light in the winter it makes more sense to use food storage then continue using energy to produce chlorophyll and continue photosynthesis. The reason for color change in the leaves are the other pigments present in plant leaves, which only show once chlorophyll production stops. These include carotenoids (yellow orange brown) and Anthocyanins (reds).
Why is it important that you keep two variables constant such as light level and color while you're testing and how does a third variable CO2 level affect photosynthesis?
The first bit, "why is it important to keep to variables constant" is so you can be sure that the thing your measuring is what is affecting the change. So if your measuring the affect of CO2 levels on the rate of photosynthesis, you need to keep light level and any other variable constant through out the whole experiment so you know that it isn't a change in the amount of light that makes the rate of photosynthesis change but the change in CO2 level. I think that makes sense! Also, CO2 increases photosynthesis until a certain point at which photosynthesis can't happen any quicker because all the chlorophyll is 'taken up' using the CO2 for photosynthesis and so the only way to increase photosynthesis rate would technically be to add more chlorophyll. This means that CO2 becomes whats called a 'limiting factor'. I think that makes less sense!
