Do plants have adaptations that maximise light absorbsion?
One of the main adaptions is the range of pigments that absorb the light in plants. From the standard P680 and P700 pigments ( named for the absorption spectrum, in nanometers, they pick up in ) in the two photosystems to many different pigments in the array of pigments surrounding the reaction center. These pigments absorb light outside the red and blue range and they become visible when the leaves of plants turn colors in the fall.
What are facts about plant pigments?
An important fact about plant pigments is that it colors the plant green. It also makes leaves yellow and orange in the fall.
Does the sugar maple leaves that change color and fall off in the fall?
Yes, each fall sugar maples (and other deciduous trees) remove the chlorophyll and other important compounds and nutrients from their leaves (which causes the other colors to become visible) and then drop the leaves.
What does the visible portion of the electromagnetic spectrum fall?
It falls within the following approximate range of frequencies:
How does plant change their color?
Generally in the fall a plant will lose it's green pigments (chlorophyll) and the result is yellow orange or red leaves.
Are yellow or orange pigments that appear in fall leaves?
the pigments become visible in the leaves as the seasons change! (A+)
Describe why you see fall colors during the fall season What happens to the green pigments that allows for the orange red and yellow pigments to be more visible?
Because the amount of sunlight is less and the weather is colder, trees allows the beta carotene (orange pigments), and other pigments, to be more visible compared to when the leaves have more chlorophyll (green pigments).
Fall leaf color on deciduous trees is a result of?
cessation of chlorophyll production, which allows the accessory pigments to be revealed.
What are examples of accessory pigments for photosynthesis?
Some examples are carotenoids and phychobiliprotein. Chlorophyll is not an accessory pigment. Accessory pigments are pigments which work alongside Chlorophyll a in photosynthesis, such as carotene.

Why do green plants have non green accessory pigments?
For many trees during the fall, chloroplasts die out and the plant loses the green look. When this occurs, other plastids such as chromoplasts must provide the plant with photosynthesis.
What pigment include yellow and orange pigments that appear in fall leaves?
Carotenoid pigments
What pigment include the yellow and orange pigments that appear in fall leaves?
Carotenoid pigments
Is the leaves changing color in the fall a chemical or physical?
Often , a color is evidence of a chemical change . Year round , leaves contain yellow , red , and orange pigments that are masked , or hidden , by large amounts of green chlorophyll . In autumn , changes in temperature and rainfall amounts cause trees to stop producing chlorophyll . When chlorophyll production stops , the masked pigments become visible
What pigment causes the yellow color of leaves in autumn?
Carotene gives yellow color to the leaves.
Why is colour change a chemical change?
The chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall splendor. At the same time other chemical changes may occur, which form additional colors through the development of red anthocyanin pigments.
How is the color of fall leaves related to the pigments in chloroplasts?
Carotenoids.
