This lesson will examine the two major classes of phototsynthetic pigments, chlorophylls and carotenoids, their biochemical structures and their biosynthesis. The organization of these pigments into photosynthetic pigments, which are protein complexes that harvest light and convert its energy into biochemical energy will be explained.


At the completion of this lesson, students will be able to:

It is in this area where the green pigment absorbs light and photosynthesis takes places.

We shall skim through some information related to this green pigment in plants that is essential for photosynthesis by going through the following Buzzle article.

In such proteins all the pigments are ordered to work well together.

Only certain wavelengths are absorbed based on what pigments the plant has.

Flavonoids are widely distributed plant pigments. They are water soluble and commonly occur in vacuoles, membrane-enclosed structures within cells which also store water and nutrients.

Carotenoids are yellow, orange, or red pigments synthesized by many plants, fungi, and bacteria. In plants, carotenoids can occur in roots, stems, leaves, flowers, and fruits. Within a plant cell, carotenoids are found in the membranes of plastids, organelles surrounded by characteristic double membranes. Chloroplasts are the most important type of plastid and they synthesize and store carotenoids as well as perform photosynthesis. Two of the best known carotenoids are Beta-carotene and lycopene. Beta-carotene gives carrots, sweet potatoes, and other vegetables their orange color. Lycopene gives tomatoes their red color. When a human eats carrots or other foods containing carotenoids, the liver splits the carotenoid molecule in half to create two molecules of vitamin-A, an essential micronutrient.

Pigments of Plants Now list the pigment colors you see in Table 3.

These pigments are embedded in plants and algae in special antenna-proteins.

Once a pigment has absorbed radiation and is excited to a higher energy state, the energy in the pigment has three possible fates: (a) it can be emitted as heat, (b) it can be emitted as radiation of lower energy (longer wavelength), or (c) it can engage in photochemical work, i.e., produce chemical changes. Flavonoids, carotenoids, and betalains are plant pigments which typically emit most of their absorbed light energy as heat. In contrast, chlorophyll, phytochrome, rhodopsin, and phycobilin are plant pigments which use much of their absorbed light energy to produce chemical changes within the plant.

The chlorophylls are used to drive photosynthesis and are the most important plant pigments. Chlorophylls occur in plants, algae, and photosynthetic bacteria. In plants and algae, they are located in the inner membranes of chloroplasts, organelles (membrane enclosed structures) within plant cells which perform photosynthesis. Photosynthesis uses the light energy absorbed by chlorophylls to synthesize carbohydrates. All organisms on earth depend upon photosynthesis for food, either directly or indirectly.

Plant Pigments and Photosynthesis

But what about the development of land plants? Why did they stay green? The thoughts are that they had plenty of light and were not pressured to develop more efficient light gathering. That is, the light was not the limiting resource in photosynthesis for plants.

Plant pigments and photosynthesis lab answers chapter 8

To a plant, sunbathing is life. Literally. In fact, plants have evolved all sorts of ways to maximize their exposure to the sun while at the same time preventing loss of critically needed water. Plants, as well as some algae and bacteria, perform photosynthesis, a process that involves the capture and use of the Sun’s energy to create biological compounds. Photosynthetic organisms generate these compounds using carbon dioxide (CO2) and water (H2O), and the products they release are oxygen (O2) and carbohydrates as byproducts.

Lab 4 Plant Pigments - Biology Junction

A plant pigment is any type of colored substance produced by a plant. In general, any chemical compound which absorbs visible radiation between about 380 nm (violet) and 760 nm (ruby-red) is considered a pigment. There are many different plant pigments, and they are found in different classes of organic compounds. Plant pigments give color to leaves, flowers, and fruits and are also important in controlling photosynthesis, growth, and development.
