Which tissue in the leaf supplies water to the cells for photosynthesis?
The xylem tissue in the leaf supplies water to the cells for photosynthesis. Xylem is responsible for transporting water and nutrients from the roots to the rest of the plant, including the leaf cells. This water is needed for photosynthesis to occur, as it is a key component in the process.
What does pH do to the structure and function of macromolecules?
pH can alter the structure of macromolecules by affecting the charges on amino acid residues, leading to changes in protein folding and stability. Changes in pH can also impact the function of macromolecules, such as enzymes, as their activity is often dependent on a specific pH range for optimal function. Extremes in pH can denature macromolecules, disrupting their structure and rendering them non-functional.
The other energy not used in photosynthesis is typically lost as heat energy during the process. Heat energy is a byproduct of many chemical reactions, including photosynthesis, and is released into the environment. This waste heat contributes to Earth's overall heat balance.
What are two main products of photosynthesis?
The 2 main products of Photosythesis are Glucose and oxygen.
Why do bubbles tell you how fast photosynthesis is occuring?

What will happen to photosynthesis if ther is no light?
Photosynthesis cannot occur without light as it is the process by which plants convert light energy into chemical energy in the form of glucose. Without light, plants would not be able to produce their own food through photosynthesis, ultimately leading to a lack of energy and nutrients that are essential for their growth and survival.
What are the 3 major stages of the light reactions?
The three major stages of the light reactions in photosynthesis are: 1) Absorption of light energy by chlorophyll and other pigments in the thylakoid membranes, 2) Conversion of light energy into chemical energy in the form of ATP and NADPH, and 3) Splitting of water molecules to produce oxygen as a byproduct.
What happens if there is an oversupply of carbon dioxide in a plant undergoing photosynthesis?
If there is an oversupply of carbon dioxide in a plant undergoing photosynthesis, the rate of photosynthesis will not increase beyond a certain point because other factors such as light intensity and temperature also play roles in the process. As a result, the plant may not be able to utilize all the excess carbon dioxide efficiently. This could lead to the accumulation of sugars and starches in the plant, potentially affecting its growth and metabolism.
Where is the energy stored by photosynthesis?
The energy is stored in the form of chemical bonds in molecules such as glucose, which is produced during the process of photosynthesis. This stored energy can then be used by the plant for various metabolic processes or transferred to other organisms when they consume the plant material.
What does the presence of blue color means in variegated leaf experiment of photosynthesis?
By blue color I assume you mean an added dye that shows how some parts of the leaf can photosynthesize and others not.
The easiest of these experiments is to place the leaf in boiling ethanol (alcohol) and when drained of colour spread out on a flat surface. Soak the leaf in iodine and the green parts will turn blue/black and the non green parts will stay the yellowish brown colour of iodine. The green parts contain starch (a more compact form of glucose) which makes iodine turn blue/black. The blue/black is what will show starch is present.
What is photosynthesis and what chemical involve in it?
Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water. The main chemical involved in photosynthesis is chlorophyll, a pigment found in the chloroplasts of plant cells that captures and absorbs light energy.
CAM (crassulacean acid metabolism) plants, such as cacti and succulents, save water by converting carbon dioxide into a special carbon compound (malate) during the night through a process known as carbon fixation. This allows them to close their stomata during the day to minimize water loss while still being able to photosynthesize efficiently.
Crassulacean acid metabolism (CAM) plants save water by incorporating carbon dioxide into a special carbon compound at night, reducing water loss during the day when stomata are closed. This mechanism allows them to adapt to arid environments with limited water availability. Examples of CAM plants include cacti, pineapple, and agave.
the gas exchange is prevented. it also limits the carbon supplies.
What will be the result of photosystem II exposed to less sunlight?
The thylakoid will have fewer hydrogen ions. For Apex
What is the chemical equation that governs the process of photosynthesis?
The overall chemical equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2 This equation represents the conversion of carbon dioxide and water into glucose and oxygen using sunlight as the energy source, carried out by plants, algae, and some bacteria.
How is carbon dioxide converted into glucose during the independent phase?
During the Calvin cycle (also known as the independent phase of photosynthesis), carbon dioxide is fixed into glucose through a series of enzymatic reactions. The enzyme RuBisCO catalyzes the combination of carbon dioxide with a five-carbon sugar molecule, which results in the formation of a six-carbon compound. This compound is then broken down and converted into glucose through a series of steps involving ATP and NADPH that provide the energy and reducing power needed for the process.
Dependence on other countries for raw materials and markets increased the interest of the US global?
stability
Who committed aggression to find raw materials?
Various historical examples exist of countries or empires committing aggression to acquire raw materials, such as European colonial powers exploiting resources in Africa and the Americas, Japan's expansion in Asia for resources like oil and rubber, and more recent instances of resource-driven conflicts in the Middle East.
Describe the of the Calvin cycle in the third stage of photosynthesis?
One three-carbon sugar is used to make organic compounds (energy-storing compounds.)
What energy is found in flute?
The energy found in a flute comes from the vibrations of the air column inside the instrument when a player blows air across the mouthpiece. This energy is converted into sound waves that produce the flute's musical tones.
Why is the first stage called the light dependent reaction?
it is the first stage because the product of the light dependent reaction is ATP and NADPH+H+ (Nicotinamide Adenine Dinucleotide Phosphate Hydrogen) and these are required in the light independent reaction (calvin-benson cycle)
I hope this helps :DDD
