The end products of respiration are carbon dioxide and water. 5. The energy released Difference between Photosynthesis and Respiration | Plant Physiology. The Relation between Photosynthesis, Respiration, and Crassulacean Acid in extracts from Aloe leaves and from other plants and studies of leaf anatomy and. Learn about and revise photosynthesis with BBC Bitesize for GCSE Combined Some is used for the plant's respiration, and the rest is released which makes it.
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. 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.
Photosynthesis and Respiration
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!
This creates a sugar chain and six units of oxygen. Chlorophyll is green because the light required for photosynthesis is red and blue light, leaving green light to be reflected back to our eyes.
Plants Photosynthesis occurs in the leaves of plants with little to none in the stems. Plant leaves are made of upper and lower epidermises, mesophyll, veins, and stomates. Mesophyll is the layer of the plant that contains chloroplasts and is the only place photosynthesis occurs. The energy taken is stored as ATP adenosine triphosphate. It is required for energy storage and is made of the nucleotide adenine with ribose sugar.
Sciencing Video Vault Respiration The respiratory system allows living creatures that are not plants to obtain oxygen from the air for use in the blood and cells. Oxygen is a much needed nutrient and living organisms can roughly only survive for minutes without it. Plants produce more O2 than they need, so most of the O2 is released into the air as waste a.
The Differences Between Photosynthesis & Respiration | Sciencing
One tree can produce enough extra O2 for adults b. That CO2 is then available for the plants to use again for making their own food i. It's a cycle of interdependence - organisms that photosynthesize depend on organisms that respire for CO2 and respirers depend on photosynthesizers for food and O2 It's a cycle of interdependence! Almost all consumers depend on photosynthesizing organisms directly or indirectly for food and O2 1.
How does the carbon cycle relate to photosynthesis and respiration?
Primary consumers need plants for food and oxygen so they may turn their food into energy through respiration 2. Other consumers need plants to feed the primary consumers they eat and to turn their food into energy Photosynthesis video Here's another tutorial about photosynthesis.

One error in this tutorial, however, is when they say that plants do not need oxygen. But they make more than they need, so most of the oxygen is released into the air.Photosynthesis and respiration - Chemistry for All - The Fuse School
