Photosynthesis Process in Plants
Words • 371
Pages • 2
What happens to carbon atom during photosynthesis?(Light dependent reactions) ·Light depended reactions occur inside the thylakoids. When the chlorophyll molecules absorb sunlight they give off high energy electrons. They move through a series of electron carrier proteins called electron transport chains in the thylakoid membrane. The proteins in the electron transport chain use the energy to pump hydrogen ions into the thylakoid from the surrounding stroma. The stroma is the gel like fluid inside the chloroplast. The hydrogen ions pumped…...

Calvin Cycle a Part of Photosynthesis
Words • 300
Pages • 2
The Calvin Cycle is basically a part of photosynthesis where plants take in carbon dioxide and uses ATP and NADPH to make sugars from the CO2 and water for the plant to use or for animals to eat. It does not require light, and is interestingly called the "dark cycle" The first step of this cycle consists of A carbon atom from carbon dioxide molecule will enter the cycle and joins with a five carbon molecule that is present. The…...
Investigation to find out how light intensity effects the rate of photosynthesis
Words • 3198
Pages • 13
Flowering plants, like all living organisms, need a supply of food. They need it as a source of energy in respiration and they need it as raw material for growth and repair. Animals and most micro- organisms get their food in an organic form: they eat products from other organisms (such as fruit and eggs) or, nowadays, the organic substances made in laboratories and factories. Animals and the microorganisms that do this are called consumers. Due to the flowering plants…...

Investigating the effect of temperature on the rate of photosynthesis
Words • 8156
Pages • 33
Before starting my investigation on how temperature affects the rate of photosynthesis I carried out some research into photosynthesis. From this initial research I made a prediction based on the evidence that I found about the enzyme rubisco that is used in the dark stages of photosynthesis, and also on the limiting factors of light intensity, carbon dioxide concentration and temperature. I then went on to carrying out a preliminary experiment from which I learnt the factors that made the…...
The Rate of Photosynthesis on Plants
Words • 224
Pages • 1
When organisms like cyanobacteria, algae, and primarily green plants use the energy from light and turn this energy into carbon dioxide, or water into oxygen and sugar, this process is called photosynthesis. The equation for photosynthesis is 6C02 +6H20+light energyв†’ C6H12O6 + 6O2 (Newton, 2019). The sugar created is stored in the starch. Starch is then used as fuel for plants, these are heterotrophs and autotrophs (Newton, 2019). In photosynthesis, there are two stages that are light-dependent. Light-dependent means that…...

Aerobic respiration is the process for transforming Glucose into Co2(Carbon dioxide). and H20(Water as waist product) with the participation of oxygen (O2) for produces energy. As a function, aerobic respiration provides fuel for the repair, growth, and maintenance of cells and tissues. It is the process by which many cells, produce energy using nutrients and oxygen. It also gives rise to carbon dioxide, which later must then release. (equation a mettre). This equation explains why both nutrients and oxygen are…...

The variables that could change the rate of photosynthesis are: Temperature, light intensity, Co2 concentration and amount and type of weed. The variable I will change is Co2 concentration. The variable that we have changed, Co2 concentration will change the variable we measure in that the higher the concentration of Co2 is the higher the rate of photosynthesis. But at a certain point the rate of photosynthesis will level out and no longer increase. Explanation: It slows due to the…...

I predict that the ivy plant that grows on the south side of the wall will be smaller than the north facing ivy. This is because they have less limiting factors affecting them such as availability of light. The south side ivy have no problem with availability of light as the earth is tilted on its axis facing the sun, so this side has more sunlight. The purpose of the leaves to be able to photosynthesise, so I think that…...

One of the seven processes carried out by all living organisms, nutrition occurs in both plants and animals. However, the methods they both use are very different. Autotrophic nutrition is in its simplest terms is being able to feed oneself and synthesise ones own food from simpler molecules. Hetrophic nutrition however, is the opposite, unable to synthesise its own food. Immediately, one notices which of the categories each the plants and animals fall into. It is important to stress that…...

Photosynthesis and respiration are both processes that are necessary for the survival of organisms. However, in numerous ways these two processes are very diverse as they are responsible for distinct necessities. Therefore they both have similarities and differences. One major difference between the two is that photosynthesis takes place completely in plants while respiration occurs equally in plants and animals. Nevertheless to understand Photosynthesis and respiration, we need to understand what is photosynthesis and cellular respiration and examine each of…...
