Also, the at very cold temperatures and very hot temperatures the rate of photosynthesis did not occur at all, but in temperature close to 20 degrees Celsius (10,30,40 Celsius) photosynthesis did occur but at a slower rate.
Since we put the plant in different environments different degrees (O,10,20,30,40,and 50 degrees Celsius) the temperatures rose until it reached 20 degrees Celsius then after it hit its climax the amount of oxygen gradually decreased.
The results from the simulation were that at 20 degrees Celsius the amount of oxygen (41.1 mL/h) from the plant increased dramatically showing that the rate of photosynthesis was faster when the plant's environment temperature reached 20 degrees Celsius.
This process is extremely important for life on earth as it provides the oxygen that all other life depends on.
Just like humans and other living things, plants also need this food for many things. Let's see a few:
Glucose resulting from photosynthesis is used during respiration to release energy that the plant needs for other life processes.
The plant cells also convert some of the glucose into starch for storage. This can then be used when the plant needs them. This is why dead plants are used as biomass, because they have stored chemical energy in them)
Glucose is also needed to make other chemicals such as proteins, fats and plant sugars that are all needed for the plant to carry out essential growth and other life processes.
what does photosynthesis need? | Yahoo Answers
Every plant needs light to grow and flourish, but the right amount of sunlight varies. When choosing plants for your garden, look at the plant label to check its light requirements. No matter what light conditions your garden has to offer, at least something should be able to grow there.
BBC - GCSE Bitesize: Photosynthesis
Most plants contain a special colored chemical or pigment called chlorophyll that is used in photosynthesis. Chlorophyll is what absorbs the sun's energy and turns it into chemical energy. Not all the light energy from the sun is absorbed.
Sunlight has many different colors in it. Chlorophyll usually absorbs red and blue light from the sun and reflects green light. It's the green light reflecting that makes some leaves look green! In the fall, some plants stop producing chlorophyll and we see leaves change color. With the chlorophyll gone, the green light is not being reflected anymore!
Why Do Plants Need Water in Photosynthesis? | Sciencing
Temperature, carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis.Plants also need mineral ions, including nitrate and magnesium, for healthy growth.
This is a very small percentage that plants need to make food ..
Plantsuse a process called photosynthesis to make food. During photosynthesis,plants trap light energy with their leaves. Plants use the energyof the sun to change water and carbon dioxide into a sugar called glucose.Glucose is used by plants for energy and to make other substances likecellulose and starch. Cellulose is used in building cell walls. Starchis stored in seeds and other plant parts as a food source. That's why somefoods that we eat, like rice and grains, are packed with starch!
Photosynthesis is a process used by plants and ..
During photosynthesis, a plant is able to convert solar energy into a chemical form. It does this by capturing light coming from the sun and, through a series of reactions, using its energy to help build a sugar molecule called glucose. Glucose is made of six carbon atoms, six oxygen atoms, and twelve hydrogen atoms. When the plant makes the glucose molecule, it gets the carbon and oxygen atoms it needs from carbon dioxide, which it takes from the air. Carbon dioxide doesn't have any hydrogen in it, though, so the plant must use another source for hydrogen. The source that it uses is water. There is a lot of water on the earth, and every water molecule is composed of two hydrogen atoms and one oxygen atom. In order to take the hydrogen it needs to build glucose molecules, the plant uses the energy from the sun to break the water molecule apart, taking electrons and hydrogen from it and releasing the oxygen into the air. The electrons it takes are put into an electron transport system, where they are used to produce energy molecules called ATP that are used to build the glucose molecule-- all made possible by the sun's energy. Thus, during photosynthesis a plant consumes water, carbon dioxide, and light energy, and produces glucose and oxygen.
The sugar glucose is important because it is necessary for cellular respiration. During cellular respiration, the chemical energy in the glucose molecule is converted into a form that the plant can use for growth and reproduction. In the first step of respiration, called glycolysis, the glucose molecule is broken down into two smaller molecules called pyruvate, and a little energy is released in the form of ATP. This step in respiration does not require any oxygen and is therefore called anaerobic respiration. In the second step of respiration, the pyruvate molecules are rearranged and combined and rearranged again in a cycle. While the molecules are being rearranged in this cycle, carbon dioxide is produced, and electrons are pulled off and passed into an electron transport system which, just as in photosynthesis, generates a lot of ATP for the plant to use for growth and reproduction. This last step requires oxygen, and therefore is called aerobic respiration. Thus, the final result of cellular respiration is that the plant consumes glucose and oxygen and produces carbon dioxide, water, and ATP energy molecules.
At first, this doesn't seem to make any sense! If the plant can use the energy from the sun to make ATP, why does it go through all the trouble of then using up the ATP to make glucose, just so it can get ATP again? There are two reasons why the plant does this. First, in addition to ATP, the plant needs materials to grow. Glucose is an important building block that is necessary to produce all of the proteins, DNA, cells, tissues, etc. that are important to life, growth, and reproduction. Second, one problem with the sun is that it goes away every night, and during winter it isn't very bright. The plant needs energy all of the time. So, by producing glucose, the plant can store this molecule and then use it to produce energy during the night and over winter when there isn't enough sun to provide good photosynthesis.
It is very interesting how photosynthesis and cellular respiration help each other. During photosynthesis, the plant needs carbon dioxide and water-- both of which are released into the air during respiration. And during respiration, the plant needs oxygen and glucose, which are both produced through photosynthesis! So in a way, the products of photosynthesis support respiration, and the products of respiration support photosynthesis, forming a cycle.
While plants can complete this cycle by themselves, animals cannot, since animals aren't capable of photosynthesis! This means that animals have to survive solely through respiration. Also, since we animals can't produce glucose by ourselves, we have to get it from somewhere else-- from eating plants. We produce carbon dioxide that the plants need, and they produce the oxygen that we need, and then we eat them to get the glucose that we need. It seems that we need the plants a lot more than they need us!
