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.
Why do biologists think that ancient green algae were the ancestors of todays plants?
Because their basic cellular composition remains similar to the modern plants.
Where are the pigments located in the chloroplast?
Chloroplasts contain structures called thylakoids (this is where photosynthesis takes place); inside the thylakoid membrane are colored photosynthetic pigments.There are a total of 6 photosynthetic pigments, although 2 are by far the most important; these are known as Chlorophyll.There are two forms of Chlorophyll, Chlorophyll a and Chlorophyll b. Chlorophyll a absorbs light in the 700 mn (nanometer) frequency range and Chlorophyll b in the 680 nm frequency range of the visible light spectrum.The 6 photosynthetic pigments are:Chlorophyll a (C55H72MgN4O5) is blue-green in color (reflects this colour)Chlorophyll b (C55H70MgN4O6) is yellow-green in colorCarotene is orange in colorXanthophyll is yellow in colourPhaeophytin a is grey-brown in colorPhaeophytin b is yellow-brown in colorThe different locations and concentrations of these pigments give plants their various colors.The main pigments found In chloroplast is CHLOROPHYLL.
How does it benefit a plant to have Multiple pigments?
different pigments have different wavelengths of light which it can absorb... so helps to increase the range of wavelengths of light that can be absorbed... also helps to avoid photo oxidation of the main plant pigment..
Why do chloroplasts have a range of pigments?
Different pigments respond to different wavelengths of visible light.

Pigments that expand the range of wavelengths for photosynthesis are called?
Antenna Pigments

Why are accessory pigments not visible?
The range of light absorption in leaves is extended by some accessory pigments. But it does not cover the entire visible range.
What pigment traps the energy for photosynthesis?
There is a wide range of pigments that are used for photosynthesis. However, chlorophyll is responsible for using obtained light energy to excite electrons to move through the transport chain. Many pigments are only capable of transferring energy to chlorophyll, but they are important because they increase the spectrum of the frequencies of light of which the organism can use to photosynthesize. These pigments are called accessory pigments. For a more detailed explanation of these pigments, view the attached link below.
What plant pigments are found in plants other than the green pigments?
Carotene - an orange pigmentXanthophyll - a yellow pigmentPhaeophytin a[1] - a gray-brown pigmentPhaeophytin b[1] - a yellow-brown pigmentThese are some of the other pigments found in plants other than green pigments.
What did The ancient Egyptians and Greeks tint their sculptures with?
The ancient Egyptians tinted their sculptures with a range of natural pigments, including red, blue, yellow, green, and black. These pigments were derived from minerals, plants, and animals. On the other hand, the ancient Greeks primarily used paints made from natural pigments such as red ochre, yellow ochre, and lead white to tint their sculptures.
What is the Benefits of having several different pigments is that?
it can be used in a broader range of photosynthesis
What is the difference between accessory pigments and chlorophyll?
Carotenoids are mostly yellow-red-orange-brown in colour, chlorophyll is green. Carotenoids serve two main purposes in plants - protection from exces sunlight (a bit like sun-screen), and they can absord some sunlight which they then transfer to chlorophyll. Chlorophyll absords sunlight and is involved in photosynthesis.
