Overview of Photosynthesis | Boundless Biology

When dolphins are 'rescued' in various countries, the car given seems to be ill-considered. We are simply looking at the success rate which is reported to be low, in most places. They could even end up in commercial aquarium shows, but they certainly rarely make it back to the sea.

The reducing power is provided by NADPH, which acquired energized electrons in the light reactions.

Orchids require special fertilizer designed for orchids to grow really well. A common ingredient in many off-the-shelf fertilizer formulas is Urea which is not well absorbed by orchids. As a result, it is best to obtain a fertilizer that is made for orchid care. The gold standard for orchid fertilizer is based upon a formula created as the result of a study at Michigan State University (MSU). Our is genuine MSU fertilizer from the same folks who supplied fertilizer for the original study. Orchids do not require very much fertilizer; a diluted amount on a regular basis is optimal for orchid care. Most orchid growers recommend fertilizing "weakly, weekly".

Pot your orchids in the smallest pot that the roots will fit in and stake the plant while it establishes itself. The orchids we've seen grow the best are often growing in what appears to be ridiculously small pots so resist the urge to 'pot up' any more than is absolutely necessary to hold the roots. make it easy to see the roots and to see when to water. The potting mix turns dark when wet and gradually lightens as it dries. also allow for some photosynthesis while being a very attractive choice for display as well. Unlike clay, plastic pots are easy to clean, disinfect, and reuse. Clear plastic pots are a great way to keep an eye on what is happening in the pot without having to disturb the plant. Exotic enhance the beauty of any orchid and are great for displaying a plant in bloom.


The objectives are the steps needed to get there

For photosynthesis to occur, plants need: · Light energy from the sun · Chlorophyll to absorb light energy · Carbon dioxide from the atmosphere and from respiration in plant cells · Water which is absorbed by the roots and transported to the leaves by the xylem tubes....

Proper orchid watering is probably the single most difficult aspect of orchid care to get right. The appropriate amount of water for an orchid varies with the type of orchid, the type of mix it is in, and the environment in which the orchid is growing. This is as difficult for beginners as using a recipe that suggests that a dish be "baked until done", what does that mean? Orchids want the 'right' amount of water, not too much and not too little. The right amount also varies with the seasons, orchids dry out more quickly when it is hot then when it is cold. The key is to vary the frequency of orchid watering, the type of pot, the type of mix, how tightly the mix is packed and the amount of air circulation until the right balance is achieved for each orchid. This takes time and patience but pays off with increased health and vigor of the orchid which translates into increased blooms. The one thing to avoid is to limit the amount of water that an orchid is given during a watering. By & large one is met with the greatest success when an orchid is watered liberally, allowing the water to pour from the bottom of the pot, until the plant and media are completely saturated. From a practical standpoint this usually means bringing the orchid to the sink and running water liberally through the mix. In some cases one can water an orchid on its humidity tray especially if that tray has a drain in case the water level gets too high. Once the orchid has been watered it should go back to its growing space until the next watering which may be anything from a few days to a week or more later. Establishing a routine can help, for example watering on the weekend and checking the plants midweek. When in doubt, wait, too little is better than too much.

At the beamline, the researchers mixed the cobalt catalyst with a ruthenium-based photosensitizer. This photosensitizer is energized by light and can pass that energy to the catalyst to jumpstart the reaction. They also added ascorbic acid to the mixture. The ascorbic acid acts as an electron donor, which provides a source of electrons for downstream reactions. The sample is flown into a free-flowing liquid jet sheet in the path of the x-ray beam and excited with an optical laser. The light sets the reaction in motion, with the photosensitizer funneling electrons from the donor to the catalyst. As the reaction progressed, the x-ray data showed that the structural environment around the cobalt metal center changes over the course of the reaction and also allowed the observation of the cobalt cycling through different oxidation states.

It will be very interesting to see how light will influence the rate of photosynthesis in plants and what will happen if they do not get the required light in order to produce starch .
