Are photosynthetic pigments and accessory pigments the same?
No, photosynthetic pigments are the main pigments involved in capturing light energy for photosynthesis, such as chlorophyll. Accessory pigments are additional pigments that assist in light absorption and broaden the range of light wavelengths that can be utilized for photosynthesis, such as carotenoids and phycobilins.
Why do algae have different photosynthetic pigments from plants?
Algae have different photosynthetic pigments because they inhabit diverse environments and need to adapt to varying light conditions. The different pigments enable algae to absorb light efficiently across a wider range of wavelengths, allowing them to thrive in environments that may not be suitable for land plants.
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.
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.
Why do biologists think that ancient green algae were the ancestors of todays plants?
Biologists believe ancient green algae were the ancestors of today's plants because they share similar characteristics, such as photosynthetic pigments and cell wall composition. Fossil evidence also supports the evolutionary link between green algae and plants. Additionally, genetic studies have revealed a close relationship between the two groups.

What are the three main photosynthetic pigments?
The three main photosynthetic pigments are chlorophyll a, chlorophyll b, and carotenoids. Chlorophyll a is the primary pigment involved in photosynthesis, absorbing light energy and converting it into chemical energy. Chlorophyll b and carotenoids help broaden the range of light wavelengths that can be absorbed by the plant.

What colors do accessory pigments reflect?
Accessory pigments typically reflect colors such as red, orange, and yellow. These pigments help plants absorb a wider range of wavelengths of light for photosynthesis.
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.
Does accessory pigments allow plants to absorb visible light of intermediate wavelengths?
Yes, accessory pigments enable plants to absorb visible light of intermediate wavelengths that chlorophyll alone cannot effectively capture. These pigments, such as carotenoids and phycobilins, broaden the spectrum of light absorption, allowing plants to utilize a wider range of sunlight for photosynthesis. By capturing additional wavelengths, accessory pigments enhance the overall efficiency of light energy conversion in plants.
Why do plants need a variety of different pigments?
Plants need a variety of different pigments to absorb a range of wavelengths of light for photosynthesis. Each pigment absorbs light at different wavelengths, allowing plants to capture energy from different parts of the light spectrum. This increases the efficiency of photosynthesis and helps plants thrive in various environmental conditions.
Why do plants have pigments other than chlorophyll?
Plants have pigments other than chlorophyll, such as carotenoids and anthocyanins, to absorb different wavelengths of light for photosynthesis. These pigments help capture a wider range of light energy and protect plants from excess sunlight by dissipating harmful energy. They also play a role in attracting pollinators and protecting plants from stressors like UV radiation and pathogens.
Pigments that expand the range of wavelengths for photosynthesis are called?
Antenna Pigments
