What is the relationship for photosynthesis?
Photosynthesis occur at these chloroplasts. Which are small organelles that plants have the plants take the carbon dioxide plus water and energy from the Sun.
What is the relationship between the 2 processes in photosynthesis?
These two processes are responsible for the exchange of oxygen and carbon dioxide between living organisms and the environment. Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product.
What is the relationship between photosynthesis and RESP?
The cycle of photosynthesis and respiration maintains the balance of oxygen and carbon dioxide. Photosynthesis produces the oxygen to replenish oxygen that is used up by living organisms during respiration. Carbon dioxide produced during respiration is one of the reactants plants need to perform photosynthesis.
How does photosynthesis link plant growth?
During photosynthesis, carbon dioxide, a gas, is combined with water and solar energy, and converted to carbohydrates, a solid. Formation of carbohydrates is a chemical way to store the sun’s energy as “food.” Carbohydrates produced from photosynthesis provide energy for all plant growth and maintenance.
What is the process of photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Why is photosynthesis important?
Photosynthesis sustains life on Earth today by releasing oxygen into the atmosphere and providing energy for food chains. The rise of oxygen-producing photosynthesis allowed the evolution of complex life forms like animals and land plants around 2.4 billion years ago.
What are the two kinds of reactions in photosynthesis?
There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.
What are the 2 stages of photosynthesis?
While there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions.
What factors affect the rate of photosynthesis?
The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
Does more photosynthesis mean more growth?
A higher rate of photosynthesis not only causes the leaves to grow larger, but could also cause longer and thicker roots, or more abundant flowering.
What are the 4 requirements for photosynthesis?
There are four factors which are necessary for the process of photosynthesis, water, carbon dioxide, sunlight, and chlorophyll.
What are the 3 stages of photosynthesis?
The stages of photosynthesis
| Stage | Location | Events |
|---|---|---|
| Light-dependent reactions | Thylakoid membrane | Light energy is captured by chloroplasts and stored as ATP |
| Calvin cycle | Stroma | ATP is used to create sugars that the plant will use to grow and live |
What are 3 facts about photosynthesis?
10 Facts on Photosynthesis
- The green color of leaves is due to chlorophyll.
- The two main parts of a chloroplast are the grana and stroma.
- The first stage of photosynthesis captures energy from the sun to break down water molecules.
- The second stage of photosynthesis is the Calvin cycle.
What would happen without photosynthesis?
If photosynthesis ceased, there would soon be little food or other organic matter on Earth. Most organisms would disappear, and in time Earth’s atmosphere would become nearly devoid of gaseous oxygen.
What factors affect photosynthesis?
What are the 3 types of photosynthesis?
There are three main types of photosynthetic pathways: C3, C4 and CAM. They all produce sugars from CO2 using the Calvin cycle, but each pathway is slightly different.
Which factor is most important for photosynthesis to occur in plants?
Factors that influence the rate of photosynthesis
The amount of light, the carbon dioxide supply, temperature, water supply, and the availability of minerals are the most important environmental factors that affect the rate of photosynthesis in land plants.
What is the most important limiting factor in photosynthesis?
Carbon dioxide is a major limiting factor influencing the rate of photosynthesis. The concentration of CO2 is very low in the atmosphere (between 0.03 percent and 0.04 percent).
What happens when there is too much photosynthesis?
Photosynthetic organisms need to cope with a wide range of light intensities, which can change over timescales of seconds to minutes. Too much light can damage the photosynthetic machinery and cause cell death.
What are the 7 steps of photosynthesis?
Terms in this set (7)
- Step 1-Light Dependent. CO2 and H2O enter the leaf.
- Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
- Step 3- Light Dependent. The electrons move down to enzymes.
- Step 4-Light Dependent.
- Step 5-Light independent.
- Step 6-Light independent.
- calvin cycle.
What is the most important factor in photosynthesis?
Water. Water is considered one of the most important factors affecting photosynthesis. When there is a reduced water intake or availability, the stomata begin to close to avoid loss of any water during transpiration. With the stomata closing down the CO2 intake also stops which affects photosynthesis.
What are the 4 main steps of photosynthesis?
The overall process of photosynthesis can be objectively divided into four steps/ process:
- Absorption of light. The first step in photosynthesis is the absorption of light by chlorophylls that are attached to the proteins in the thylakoids of chloroplasts.
- Electron Transfer.
- Generation of ATP.
- Carbon Fixation.
What is photosynthesis in short answer?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
What are the 5 importance of photosynthesis?
Importance of photosynthesis
Photosynthesis convert radiant or solar energy into chemical energy. Productivity of agricultural crops directly depends upon the rate of photosynthesis. It provides oxygen in atmosphere for all living organisms. It maintains the balanced level of oxygen and carbon dioxide ecosystem.
