3 Ways to Explain Photosynthesis - wikiHow

Sterilization reduces the number of diseased organisms and weeds present in the soil. First, mixthe soil with an equal portion of vermiculite or peat moss (otherwise, the soil will become veryhard). Next, moisten the mixture and place it in the oven. Allow it to “bake” at 180 degrees F–200 degrees F for1 hour. Once the soil cools, it is ready to use. To treat soil in the microwave, first mix the portionwith an equal amount of vermiculite or peat moss and moisten. Place the mixture in a plasticbag. Next, consult the manufacturer’s manual to determine the amount of time and power levelneeded to heat the quantity of soil to about 180 degrees F (most portions of soil will generallyrequire about 10 to 15 minutes). Insert a probe into the soil and make sure it has heated to 180degrees F – 200 degrees F. Allow the soil to cool before using it or storing it for future use.

Mention that photosynthesis occurs mostly in plants

The findings offer breeding companies new opportunities. We now know that plants respond to light variation in their own way, and that this is determined in their DNA. We don’t yet know how these adaptations work in the plant, however, and more research is required to find out how improved photosynthesis affects the growth of the plant before we can focus on selection for this property.

Remember that the most important factors of indoor plant growth are adequate light, fertilizer,and water at reduced rates.

A clean plant is a healthy plant. Water flow causes salt accumulation along the leaf marginsand/or tips, creating necrotic areas. Dust dulls normal leaf coloration, lessening plant value, butit also shades plant surfaces, reflecting light that can be used in photosynthesis. Dust on lowerleaf surfaces may clog stomata (specialized cells involved in water transpiration), inhibiting gasexchange within the leaf. Leaves with thick, shiny cuticles (Croton, Ficus, Peace Lily,Bromeliads) should be cleaned with a damp sponge.

Photosynthesis comic, explains in detail

Scientists from Wageningen University & Research have found natural genetic variation for photosynthesis in plants and are unravelling it to the DNA level. As a result it should be possible to breed crops that use photosynthesis more effectively in the future, increasing their yield and enabling them to capture more CO2 from the air in the soil. This represents a major step on the long road to solving global food challenges and realising the Paris climate agreement.

Photosynthesis definition, the complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae. photsynthesis in plants

Chemistry for Biologists: Photosynthesis

Plants need light to convert CO2 and water into sugars and oxygen. The sugars form the basis and energy source for all the substances that a plant produces in order to grow. We have known for some time that plants can respond differently to light, as is shown in the efficiency of their photosynthesis. The ancestors of the crops we eat on a daily basis needed this variation to make the best use of the places in which they grew. It allowed them to develop both in full sunlight and in the shade of other plants.

What photosynthesis accomplishes, ..

While photosynthesis is an essential process for plants, it comes at a risk and demands a high level of control to manage energy streams. If a plant is suddenly exposed to too much light, it has to adapt to the new situation. Plants generally protect themselves against excessive photosynthesis by maintaining various safety margins, which means that the adaptation takes several days. The study by the Wageningen scientists now shows that some plants can adapt quicker than others, and are thus able to adapt their photosynthesis system to their environment sooner.

Only plants can photosynthesize, but both plants and animals depend on respiration to release the chemical potential energy originally captured through photosynthesis.
