Prediction : I predict that as I increase the distance between the light source and the Canadian Pondweed (reducing the light intensity), the volume of oxygen produced within the time limit (the measure of the rate of photosynthesis) will decrease.
It is important to have an adequate distribution system. The distribution of CO2 depends mainly on air movement within the greenhouse(s), as CO2 does not travel very far through diffusion. For instance, when a single source of CO2 is used for a large surface area or several connecting greenhouses, a distribution system must be installed. This system must be designed to evenly distribute the CO2 in the greenhouse especially when flue gas CO2 or liquid CO2 is used. Air circulation using horizontal airflow fans or fan-jet system provides uniform distribution by moving large volumes of air within the greenhouse when top vents are closed or exhaust fans are not operational. Today, growers supplementing with liquid CO2 or flue gas CO2 have a central header with small individual tubes (with evenly spaced holes) placed low in the crop canopy or in the case of bench crops, under the bench. The potential for low CO2 levels inside a dense crop canopy (chrysanthemums) makes it beneficial to supplement within the canopy. Air movement around the plants will also improve the CO2 uptake because the boundary layer around the individual leaf is lessened bringing the CO2 molecules closer to the leaf.
Can we optimise the number of chloroplasts in plants to increase their levels of photosynthesis? That way, plants can store more CO2 and play a...
The chemical equation of photosynthesis is: [IMAGE]6CO2 + 6H20 C6 H12 O6 + 6O2 it has been proven many times that plants need light to be able to photosynthesize , so you can say that without light the plant would neither photosynthesize or survive....
Scientists from Wageningen University & Research have found natural genetic variation for photosynthesis in plants and are unravelling it to the...
Background information: Photosynthesis Photosynthesis is the process of autotrophs turning carbon dioxide and water into carbohydrates and oxygen, using light energy from sunlight.
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....
A major goal for renewable energy is to achieve ‘grid parity’: the ability to provide the same amount of power as the current electricity grid at the same or lower cost. In order for photo-BES to reach this goal, it needs to be more efficient. The organisms involved in these systems still use some of the electrical energy produced from photosynthesis to survive and grow, so the energy output for other uses is reduced. Therefore, scientists and engineers are looking into modifications to increase this output and reach grid parity. For PMFCs, researchers are optimising the soil conditions for energy transfer and healthy plant growth, whilst utilising genetic technologies to derive better electrical output from soil microbes. For biophotovoltaics, work has started on increasing the ‘wiring’ of the organism into the circuit, for example by directly attaching the cells to the electrode. If successful, these steps could make photo-BESs a viable competitor to conventional solar panels.
or closely-related pigments (substances that color the plant) are essential to the photosynthetic process.
- a compound leaf that is made up of many small arranged in pairs on either side of a long central (the ).
The flowers are quite small and just protrude above the reservoir of water retained in the centre of the plant often with the down folding of the petals creating a meniscus that keeps the water from reaching the centre of the flower.
So what would the benefits of these plant solar panels be? Firstly, photo-BESs are created in smaller facilities, and therefore require much , since whole organisms can reproduce and repair themselves when damaged. Therefore, photo-BESs have great potential for delivering electricity to areas off the national grid. Also, the organisms involved in these systems are specialists at storing solar power from the sun for a supply of energy at night. Therefore the photo-BESs have potential to generate electricity in the dark, something unheard-of in current solar panels. Finally, as photosynthesis removes carbon dioxide from the air, the use of photosynthesis in solar cells has the potential to be carbon neutral.
The spongy mesophyll cells communicate with the guard cells (stomata), causing them to open or close, depending on the concentration of gases.
- (also called the axis) the main support of the plant.
- the small, paired appendages (sometimes leaf-life) that are found at the base of the petiole of leaves of many flowering plants.
- (plural stomata) a pore (or opening) in a leaves where water vapor and other gases leave and enter the plant.
There are four things that are required by the plant before it can carry out photosynthesis, they are light, chlorophyll, carbon dioxide and water ....
