These pigments are embedded in plants and algae in sorghum, sugarcane, and millet. The energy delivered to the electron acceptors is used to move hydrogen ions across the thylakoid membrane into. Many important crop plants are C4 plants, including maize, complexes called antenna proteins.

Earth supports numerous organisms that have the green pigment in which photosynthesis occurs. Some, like plants, are well-known for their role in providing air and sustenance to many ecosystems. Others, such as algae, some bacteria, and even some animals, also possess the ability to create their own sugar and use it as chemical energy. Plants, algae, cyanobacteria and even some animals conduct photosynthesis. Phytoplankton: Essential for Air Phytoplankton play an essential role in Earth's environment.

Similar to common plants, this broad category — which includes single-celled plants, bacteria and algae — uses chlorophyll to convert carbon dioxide, sunlight and water-based nutrients into oxygen. Found in both freshwater and saltwater, these microscopic organisms form the basis of life in the ocean, providing everything from larger plankton species to enormous whales with sustenance. Similar to forests, phytoplankton absorb tremendous amounts of carbon dioxide, and scientists estimate that these tiny organisms collectively create the lion's share of oxygen on Earth.

Phytoplankton span different, larger categories of photosynthesizing creatures, but their contribution to the environment is perhaps the largest.

Like plants, algae species photosynthesize to create the chemical energy they need to survive. However, algae species differ from plants in that they lack proper leaves, roots and reproductive organs.

Different algae species contain different colors of chloroplasts — green, blue-green, red and brown. Embedded within the stroma are stacks of thylakoids grana , which are the site of photosynthesis. The thylakoids appear as flattened disks. The thylakoid itself is enclosed by the thylakoid membrane, and within the enclosed volume is a lumen or thylakoid space.

Embedded in the thylakoid membrane are integral and peripheral membrane protein complexes of the photosynthetic system. Plants absorb light primarily using the pigment chlorophyll. The green part of the light spectrum is not absorbed but is reflected which is the reason that most plants have a green color.

Besides chlorophyll, plants also use pigments such as carotenes and xanthophylls. These pigments are embedded in plants and algae in complexes called antenna proteins. In such proteins, the pigments are arranged to work together.

Such a combination of proteins is also called a light-harvesting complex. Certain species adapted to conditions of strong sunlight and aridity , such as many Euphorbia and cactus species, have their main photosynthetic organs in their stems. The cells in the interior tissues of a leaf, called the mesophyll , can contain between , and , chloroplasts for every square millimeter of leaf.

The surface of the leaf is coated with a water-resistant waxy cuticle that protects the leaf from excessive evaporation of water and decreases the absorption of ultraviolet or blue light to reduce heating. The transparent epidermis layer allows light to pass through to the palisade mesophyll cells where most of the photosynthesis takes place. Light-dependent reactions Main article: Light-dependent reactions In the light-dependent reactions , one molecule of the pigment chlorophyll absorbs one photon and loses one electron.

This electron is passed to a modified form of chlorophyll called pheophytin , which passes the electron to a quinone molecule, starting the flow of electrons down an electron transport chain that leads to the ultimate reduction of NADP to NADPH. In addition, this creates a proton gradient energy gradient across the chloroplast membrane , which is used by ATP synthase in the synthesis of ATP.

The chlorophyll molecule ultimately regains the electron it lost when a water molecule is split in a process called photolysis , which releases a dioxygen O2 molecule as a waste product.

The photosynthetic action spectrum depends on the type of accessory pigments present. For example, in green plants, the action spectrum resembles the absorption spectrum for chlorophylls and carotenoids with absorption peaks in violet-blue and red light. In red algae, the action spectrum is blue-green light, which allows these algae to use the blue end of the spectrum to grow in the deeper waters that filter out the longer wavelengths red light used by above ground green plants.

The non-absorbed part of the light spectrum is what gives photosynthetic organisms their color e. The light-dependent reactions are of two forms: cyclic and non-cyclic. In the non-cyclic reaction, the photons are captured in the light-harvesting antenna complexes of photosystem II by chlorophyll and other accessory pigments see diagram at right.

The absorption of a photon by the antenna complex frees an electron by a process called photoinduced charge separation. The antenna system is at the core of the chlorophyll molecule of the photosystem II reaction center. That freed electron is transferred to the primary electron-acceptor molecule, pheophytin. The electron enters a chlorophyll molecule in Photosystem I. There it is further excited by the light absorbed by that photosystem.

The electron is then passed along a chain of electron acceptors to which it transfers some of its energy. The energy delivered to the electron acceptors is used to move hydrogen ions across the thylakoid membrane into the lumen. The cyclic reaction takes place only at photosystem I. Once the electron is displaced from the photosystem, the electron is passed down the electron acceptor molecules and returns to photosystem I, from where it was emitted, hence the name cyclic reaction.

Most marine phytoplankton are composed of diatoms and dinoflagellates. This electron is passed to a modified form of chlorophyll called pheophytin , which passes the electron to a quinone molecule, starting the flow of electrons down an electron transport chain that leads to the ultimate reduction of NADP to NADPH. These pigments are embedded in plants and algae in complexes called antenna proteins. Some scientists believe that the chloroplast in plant cells evolved through endosymbiosis, a process that saw cyanobacteria start to live within plant cells.
