Photosynthesis is a process where by energy from light is harvested and used to drive synthesis of organic carbohydrates from carbon dioxide and water. Photosynthesis takes place in chloroplasts and can be divided into two steps: light reactions which require light and dark reactions which do not require light. During light reaction, light energy is captured by photosystems and electrons are transferred among the electron receptors. ATP and NADPH are generated. During dark reactions, CO2 is fixed using ATP and NADPH generated by the light reactions and organic carbohydrates are synthesized via the Calvin Cycle. When the CO2 is first fixed into a 3 carbon compound 3PGA, it is called C3 pathways and these plants are called C3 plants. The disadvantage of C3 plants is that they undergo photorespiration and thus waste some energy gained in light reactions. C4 cycle is the pathway adopted by C4 plants to bypass photorespiration.
Algae are a very diverse group of predominantly aquatic photosynthetic organisms that account for almost 50% of the photosynthesis that takes place on Earth. Algae have a wide range of antenna pigments to harvest light energy for photosynthesis giving different types of algae their characteristic colour. Early work done with algae contributed much to what is presently known about the carbon dioxide fixation pathway and the light harvesting reactions. The processes of photosynthesis in algae and higher plants are very similar. From among the three types of carbon dioxide‐concentrating mechanisms known in photosynthetic organisms, two types are found in different types of algae. Algae are proposed to play a role in the global carbon cycle by helping remove excess carbon dioxide from the environment. Recently, algae are recognized as a promising biodiesel source due to its efficient absorption and conversion of solar energy into chemical energy.

Chloroplasts contain disc-shaped structures called thylakoids, which contain the An organelle found in the cells of green plants and photosynthetic algae where The process of photosynthesis occurs in a middle layer called the mesophyll.
Does C4 Photosynthesis Occur in Wheat Seeds
Osmosis is especially crucial to photosynthesis. Photosynthesis is the process of converting solar energy into chemical energy. Basically, the plant uses the sun to create proteins, sugars and lipids that in turn become energy for the plant’s survival. Photosynthesis primarily occurs on plant leaves and requires a combination of carbon dioxide, sunlight and water to be successful. On every plant leaf there are many guard cells that literally “guard” the stomata. A stomata is a plant pore that lives on the plant leaf surface. Stomata are responsible for plant gas exchange which enables the process of photosynthesis. What does osmosis have to do with this? The guard cells have vacuoles (remember those little cellular sacs?) that fill up with water and other fluids.
Does C 4 Photosynthesis Occur in Wheat Seeds
Osmosis is a vital function to the growth and stability of plant life. Without osmosis, photosynthesis would never occur and plants would wilt and die. A wilted plant looks wilted because the vacuoles of the cells do not have proper amounts of water. Although osmosis is still occurring, the lack of volume of water in the plant causes all of the cell walls to lose their turgor, and thus the plant loses its upright and healthy state. Osmosis distributes water through selectively permeable membranes to maintain this proper volume and pressure of all plant cells. Plant cell walls are incredibly tough and rigid which is necessary to uphold the integrity of the cell. It’s when there is adequate water that the pressure from the water can become too high in some places and through osmosis the water moves to a place of lower pressure and concentration.

Where does photosynthesis occur
The acidity was found to arise from the opening of their stomata at night to take in CO2 and fix it into malic acid for storage in the large vacuoles of their photosynthetic cells. It could drop the pH to 4 with a malic acid concentration up to 0.3M . Then in the heat of the day, the stomata close tightly to conserve water and the malic acid is decarboxylated to release the CO2 for fixing by the Calvin cycle. PEP is used for the initial short-term carbon fixation as in the , but the entire chain of reactions occurs in the same cell rather than handing off to a separate cell as with the C4 plants. In the CAM strategy, the processes are separated temporally, the initial CO2 fixation at night, and the malic acid to Calvin cycle part taking place during the day.
