Photosynthesis

This category is for questions about the chemical process in which autotrophic organisms use sunlight, carbon dioxide and water to make glucose, water and oxygen. This process is vital to life and is of great importance in biology.

How do you control Carbon dioxide concentration in photosynthesis?

Many countries, as well as individual states, cities and citizens, are taking some or all of the steps below:

  • Move to renewable energy.
  • Stop burning fossil fuels (coal, oil and natural gas).
  • Cultivate big trees and encourage reforestation and afforestation.
  • Change cement manufacturing practices to reduce carbon dioxide emissions.
  • Improve agricultural practices to minimise methane emissions.

What organisms absorb carbon dioxide?

Plants and phytoplankton are organisms that absorb carbon dioxide from the atmosphere through a process called photosynthesis. This allows them to convert carbon dioxide into oxygen and organic carbon, playing a crucial role in the global carbon cycle.

Which path does the water take to be a part of photosynthesis?

Water is absorbed by the roots of plants from the soil, then transported through the plant's vascular system to the leaves where it is used in photosynthesis. In the leaves, water molecules are split into hydrogen and oxygen during the light-dependent reactions of photosynthesis, releasing oxygen as a byproduct and providing electrons to drive the process.

What molecules supply the carbon component of carbohydrates during the Calvin cycle?

Carbon dioxide molecules (CO2) supply the carbon component of carbohydrates during the Calvin cycle. Carbon dioxide is fixed by the enzyme RuBisCO to form intermediate molecules that eventually lead to the production of glucose and other carbohydrates.

Who can photosynthesis?

Plants, algae, and some bacteria can perform photosynthesis. These organisms have chlorophyll, a pigment that captures sunlight, converting it into chemical energy to produce food (glucose) from carbon dioxide and water.

What is the evidence that there are two photosystems in plants?

The evidence for two photosystems in plants comes from experiments using isolated chloroplasts, which have shown that two distinct light reactions occur in the thylakoid membrane. Additionally, differences in absorption spectra and electron transport pathways of Photosystem I and Photosystem II provide further evidence for the existence of two separate photosystems.

How do they perform a urethrocystogram?

A urethrocystogram is performed by filling the bladder with a contrast dye through a catheter inserted into the urethra. X-ray images are taken while the bladder is filled to evaluate the bladder and urethra for any abnormalities or obstructions. This procedure helps to diagnose conditions such as urinary incontinence or urinary tract infections.

What is it called when plants take in carbon dioxide and use it for photosynthesis?

This process is called carbon fixation. Plants absorb carbon dioxide from the atmosphere during photosynthesis and convert it into organic compounds like glucose to produce energy.

What is storage plastid with the prefix meaning white in photosynthesis?

The storage plastid in photosynthesis with the prefix meaning white is called a leukoplast. Leukoplasts are colorless plastids that store nutrients such as starch.

When plants do photosynthesis carbon dioxide enters the plant because there is more carbon dioxide in air than the plant what is this an example of?

This is an example of diffusion, where molecules naturally move from an area of higher concentration to an area of lower concentration. In this case, carbon dioxide moves from the air (higher concentration) into the plant (lower concentration) during photosynthesis.

What is the name of the process where ATP is made from food molecules?

The process is called cellular respiration. It occurs in the mitochondria of cells and involves breaking down food molecules to produce ATP, the main energy currency of the cell.

How do plants grow in different lighting?

Plants require light for photosynthesis, which is the process by which they convert light energy into chemical energy to fuel growth. Different plants have varying light requirements - some thrive in direct sunlight, others in partial or low light conditions. Light intensity, quality, and duration all play a role in how well plants grow and develop.

Are photosystems clusters of chlorophyll and proteins?

Yes, photosystems are clusters of chlorophyll and other pigments, as well as proteins, that are essential components of the light-dependent reactions in photosynthesis. They work together to absorb light energy and initiate the electron transport chain that drives the production of ATP and NADPH.

Why would it behard to find the ideal co2 level if the light intensity were very low?

It would be hard to find the ideal CO2 level if the light intensity were very low because plants rely on light for photosynthesis, which produces the energy they need to utilize the CO2. If there is low light, the plant's ability to uptake and use the CO2 efficiently is compromised, making it difficult to determine the optimal CO2 level needed for healthy growth.

What is difference between charophyta and chlorophyta?

Charophyta is a group of green algae that includes charophyceans, which are the closest algal relatives to land plants, while Chlorophyta is a diverse group of green algae with a wide range of body forms and habitats. Charophytes have complex multicellular structures and reproductive strategies similar to land plants, while chlorophytes tend to be more simple in structure and reproductive processes.

Which structures in the leaf are responsible for photosynthesis?

Chloroplasts, containing chlorophyll, are the main structures responsible for photosynthesis in plant leaves. They are found in the cells of the mesophyll layer, particularly in the palisade and spongy mesophyll cells. These chloroplasts capture light energy and convert it into chemical energy through the process of photosynthesis.

Which material used in photosynthesis is obtained from the soil?

Mineral nutrients such as nitrogen, phosphorus, and potassium are obtained from the soil during photosynthesis. These nutrients are essential for plant growth and are absorbed through the plant's roots.

How are the photosynthesis and cellular respiration equations related?

photosynthesis equation is H2O+Co2->(ATP+) C6H2O6+O2 cellular reapiratation is O2+C6H2O(-> ATP)+Co2+H2O. so photoshynthesis eqaution backwards is celluar respirations equation. and they also have all the same stuff in them (water, carbon, energy, glucose, and oxygen.)

What does photosynthesis convert h2o and co2 into?

Photosynthesis converts water (H2O) and carbon dioxide (CO2) into glucose (sugar) and oxygen (O2). This process occurs in the chloroplasts of plant cells, where sunlight is used as the energy source to drive the chemical reactions.

Is a plant part that cant do photosynthesis the roots?

Yes.

Photosynthesis turns sunlight into food for the plant. Because the roots are underground, they don't get any sunlight. This prevents them from performing photosynthesis.

Does photosynthesis and respiration both produce carbon dioxide?

No, they do not both produce carbon dioxide. Photosynthesis uses carbon dioxide to produce oxygen and glucose, while respiration uses oxygen to break down glucose and produce carbon dioxide as a byproduct.

What 4 products are produced by the cell during cellular respiration?

The four main products produced by the cell during cellular respiration are ATP (adenosine triphosphate), carbon dioxide (CO2), water (H2O), and heat. These products are essential for providing energy for cellular processes and maintaining metabolic functions in the body.

What are the raw materials of photothynsesis?

The raw materials of photosynthesis are carbon dioxide (CO2) and water (H2O). These are used by plants, algae, and some bacteria to produce glucose and oxygen in the presence of sunlight.

What is produced in the second phase of photosynthesis?

The second phase of photosynthesis is called the light-independent reactions, also known as the Calvin cycle. In this phase, the products of the light-dependent reactions, ATP and NADPH, are used to convert carbon dioxide into glucose. So, the main product of the second phase of photosynthesis is glucose.

Do cell walls help a plant go through photosynthesis?

Cell walls provide structural support and protection to plant cells but do not directly participate in photosynthesis. Photosynthesis occurs in the chloroplasts, which are organelles within the plant cells. The cell walls play a role in maintaining the overall structure and shape of the plant.
