Was Van Was Van Helmont successful in what he set out to prove?
Van Helmont was successful in his experiments and research in the field of chemistry and biology, but he was not always correct in his conclusions. One of his most famous experiments, the willow tree experiment, led to the discovery of photosynthesis, but his theory of spontaneous generation was later proven false. Overall, Van Helmont made significant contributions to science despite some inaccuracies in his beliefs.
How much light do herbs need for photosynthesis and growth to occur?
Herbs generally require 6-8 hours of sunlight per day to thrive. This amount of light enables them to carry out photosynthesis effectively, leading to healthy growth and development. Insufficient light may result in stunted growth and adversely impact the plant's overall health.
Is sugar stored in the plants cells for later use in photosynthesis?
Plant cells contain organelles called chloroplasts, which contain pigments which absorb and reflect varying colors within the spectrum of visible light. The pigments in green plants absorb all colors of the visible light spectrum, except for green, which is reflected, giving the green color we see. The color of plants is dictated by which colors of the spectrum are reflected by the pigments in that particular plant's chloroplasts.
What natural process remove carbon dioxide from the air?
Photosynthesis is a natural process that removes carbon dioxide from the air. During this process, plants use sunlight to convert carbon dioxide into energy while releasing oxygen as a byproduct. This helps to regulate the levels of carbon dioxide in the atmosphere and is essential for maintaining a balance in the Earth's ecosystems.
What word is used to describe organisms which use oxygen in their cellular respiration pathways?
Oxidative phosphorylation. In this process ATP is synthesized from ADP that is coupled to the operation of the mitochondrial electron transport system.
What is chlorophyll and what does it do in photosynthesis?
Sunlight is captured by pigments (chlorophyll) in Photosystem II. This provides energy which causes photolysis - the splitting of water into 2H+, O, and electrons. (Or 2 positive hydrogens and 1 positive oxygen).
Why is DNA important to the process of photosynthesis?
DNA plays a crucial role in photosynthesis by encoding the instructions for synthesizing proteins that are essential for the process. These proteins are involved in capturing light energy, converting it into chemical energy, and carrying out the complex reactions of photosynthesis. Without DNA, the synthesis of these proteins would not be possible, leading to a disruption in the photosynthetic process.
What alkaline earth metal is part of the reaction process of photosynthesis?
Magnesium is the alkaline earth metal that is important in the reaction process of photosynthesis. It is a key component of chlorophyll, the pigment that absorbs light energy in plants and is essential for converting carbon dioxide and water into glucose and oxygen during photosynthesis.
How do energy and matter interact in the photosynthesis process?
cookies are powerful they fall from the sun mixing with light creating glucose true story
Are Mitochondria where photosynthesis take place?
No. photosynthesis takes place in the chloroplasts containing chlorophyll. our cells have mitochondria but not chloroplasts. Therefore, we can't photosynthesize as plants do.
What pigment absorbs from primary color?
Cyan absorbs red light, magenta absorbs green light, and yellow absorbs blue light as primary colors in the subtractive color model.
How does over supply or under supply of the Co2 concentration affects the rate of photosynthesis?
An oversupply of CO2 can initially increase photosynthesis rate until another factor like light or nutrients becomes limiting. Conversely, an undersupply of CO2 will limit photosynthesis since it's one of the key reactants in the process. A balanced CO2 concentration is crucial for optimal photosynthetic activity.
What raw materials do you need to manufacture the weapon industry?
Raw materials needed for manufacturing weapons can include metals such as steel, aluminum, and titanium for the weapon components, as well as plastics, polymers, and composite materials. Other materials like gunpowder, propellants, and explosives may be necessary for ammunition production. Additional components may vary depending on the type of weapons being produced.
If this experiment is performed, the researchers should carefully design and carry out the experiment to test the hypothesis. They would need to control variables such as light intensity, temperature, and carbon dioxide levels while measuring the rate of photosynthesis in plants exposed to varying wavelengths of light. The data collected would then be analyzed to determine if there is a significant impact of shorter wavelengths of light on the rate of photosynthesis.
What is the main characteristics of the first stage of photosynthesis?
The main characteristic of the first stage of photosynthesis, called the light-dependent reactions, is that it takes place in the thylakoid membrane of the chloroplasts. During this stage, light energy is absorbed by chlorophyll and converted into chemical energy in the form of ATP and NADPH, which are used in the next stage of photosynthesis to produce glucose.
What percent of light energy is fixed during photosynthesis?
plants only capture 1% of the radiant enery from the sun used in photosynthesis.
Solar radiation peaks in energy in the mid-yellow range. Chlorphyll's absorption also peaks in this range. It is a demonstration of the adaption of plants to optimizing their production efficiency.
What are two organelles in the Cell that are involved in photosynthesis?
Chloroplasts and mitochondria are two organelles involved in photosynthesis. Chloroplasts are the main site where photosynthesis occurs, while mitochondria are responsible for producing energy from the products of photosynthesis.
Why does the rate of photosynthesis stays the same at a certain temperature?
Why The Temperature Stays The Same
During a phase change, the average energy of the particles remains the same, but, the particles are rearranging themselves. Particles become less organized as their energy increases, so the substance changes from a solid to a liquid to a gas. As the energy of the particles becomes less, the particles rearrange themselves more orderly, so a gas changes to a liquid and then to a solid. The total energy of the particles changes - by increasing or decreasing, because the particles are not increasing or decreasing their speed, just their arrangement. The average energy doesn't change. The energy change is hidden from a thermometer and is called 'hidden heat' or 'latent heat'.
What is needed by the Calvin Cycle?
The Calvin cycle is a 'light independent cycle' that takes place in the chloroplasts. In this cycle, water and carbon dioxide is converted into organic compounds. The key enzyme involved is Rubisco.
What is the process by which green plants convert sunlight to energy?
The process is called a photosynthesis. Plants make glucose and oxygen from: sunlight and carbon dioxide.
That's why deforestation is so dangerous; without plants carbon dioxide levels would quickly build up - which contributes to global warming as well as increases the concentrations of CO2 in the atmosphere
What is the negative effect of the photosynthesis?
One potential negative effect of photosynthesis is the production of excess oxygen during the process, especially in aquatic environments where it can lead to oxygen depletion and harm aquatic organisms. Additionally, in urban areas, photosynthesis can contribute to the formation of ground-level ozone, which is a pollutant harmful to human health.
How does photosynthesis and cellular respiration relate to global warming?
well it is said that plants can help stop global warming. So, they have photosynthesis and do cellular respiration to take in carbon dioxide and make it oxygen. global warming has to do with carbon dioxide. there you go! :)
