KS3 biology Quiz on "PLANTS and PHOTOSYNTHESIS" …
Chemically speaking, respiration is photosynthesis in reverse, as you can see in this equation:
Chemical formula for photosynthesis
The Light Reactions(4.1) In the chemical reaction for photosynthesis, six molecules of water and six molecules of carbon dioxide react in the presence of chlorophyll and sunlight to produce one molecule of sugar plus six molecules of oxygen.
We exhale the carbon dioxide that plants need for photosynthesis.
Many scientists contributed to the discovery and understanding of photosynthesis throughout the ages; in this page are outlined some of those crucial milestone experiments that contributed to this effort.
Jan Baptista van Helmont, Flemish physician, chemist, and physicist, in the 1600s carried out a famous experiment by growing a willow tree in a pot for five years.

This is an often misunderstood aspect of aquarium plant keeping.
There is so much anecdotal information that is out of date with more current aquarium/plant biochemistry information. Not only do plants need many of the minerals found in GH, but, just as important, potentially dangerous upward pH swings can occur if your GH is much below 50 ppm during peak plant photosynthesis.
For example, I observed a pH of 6.8 in the morning and then a pH of 7.4 in the afternoon in a tank where GH was low or almost non-existent.
*Hagen Natural Plant CO2 system: this system is popular with many plant keeping aquarists.
However, (in my experience/opinion) this system is overrated and overpriced (for a yeast method). The "steps" used in the diffusion process of the Hagen unit do not increase CO2 absorption any more than the other basic CO2 kits/systems such as the Sanders Floramat or Jungle system. This is especially true if the DIY diffuser noted in the next section is employed with the Jungle Fizz or even a homemade yeast method. As well, these steps tend to clog with algae and even small snails in some instances.
In my opinion this is a more gimmicky device (the ladder, that is) and is not as reliable in CO2 delivery. That should not be construed to mean that this CO2 system does not work. It does. It simply is not any better than the previously described methods.
That being said, although I have not used a different diffusion method such as the DIY method noted later in this article, this type of DIY diffuser could likely be added to the Hagen CO2 system in place of the ladder/steps and despite the expense when compared to DIY yeast methods, the Hagen yeast packets are quick and simple (but then so are the Fizz Tabs by Jungle too).

Flash cards are a good idea if you like to memorize different facts. Barron’s AP flash cards are perfect for your biology needs. They cost $16.84 and you get 500 of them covering 20 categories. Some of them are molecular genetics, hormones, photosynthesis, and immunology.
As per the "Walstad Method" (basically, a twist on what was known by old timers as the "German Method"), this method depends upon the plants (along with fish wastes) to do most of the work for maintaining the aquarium chemistry and water quality (as far as the Nitrogen Cycle ONLY) while the aquarium keeper provides circulation, some ferts and mineral cations that are not supplied or kept up with adequately by fish food, and cleanings ONLY when necessary.

What is a Solar Water Heater
through their roots, plants absorb water and minerals from the soil
essential food from rainwater is absorbed through the leaves

The net process of photosynthesis is described by the following equation: 6CO2 + 6H2O + Light Energy = C6H12O6 + 6O2 This equation simply means that carbon dioxide from the air and water combine in the presence of sunlight to form sugars, oxygen is released as a by-product of this reaction....

Through reading various books and web pages it was made clear that carbon dioxide is definitely one of the raw materials needed for photosynthesis, but I wanted to see whether this is actually true and if carbon dioxide is taken away completely will the plant photosynthesize at all.
This NPC is the objective of Taralune
Environmental scientists recognize that the fundamental source of energy for most life on earth is the sun. Through photosynthesis, plants capture the light and convert it into chemical potential energy. Plants then store the potential energy in the form of (biological matter that fuels nearly every animal on earth).

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.
SBI3U Grade 11 University Biology Exam— onstudynotes
For those needing a bit more economy, but cannot afford a well made/longlife HO LED such as the GroBeam or AI Hydra, instead of the shotgun emitter, low quality daisy chain drivers of Fluval, Current Satellite, or Finnex LEDs, a consideration would be the relatively new SHO (Super High Output) compact fluorescent lamps (CFL).
These use 65, 85, & 105 watts, however these awesome bulbs put out the equivalent of 325, 425 and 525 watts respectively! (Pictured to the left and below in a photo-shop example of placement.)
Honestly, for any aquarium plant keeper who is remotely handy in DIY projects, the , especially for tanks over 50 gallons. Many in the green house industry have already discovered this lamp for its plant growing capabilities, which for the price there is simply no equal for planted aquariums!
The aquarium hobby/industry is much slower to adopt many technologies and this light is a major example of this. Without question, this is the lamp that could or should be used by any serious planted freshwater aquarium keeper.
