How does photosynthesis help plants meet there basic needs?
Photosynthesis was invented by the algae about 2.4x109 years ago.
It is the process by which H2O can be split into H2 and O2.
The H2 can then be used by the plant to make more complex chemicals, organic compounds containing both H and O. Some examples sugar, starch, lignin and so on.
What does a thylakoid do during photosynthesis?
Thylakoids are where the light-dependent reactions of photosynthesis occur. They contain chlorophyll and other pigments that capture light energy and convert it into chemical energy in the form of ATP and NADPH, which are used to drive the synthesis of sugars in the Calvin cycle.
How are the processes of aerobic respiration and photosynthesis interrelated?
Aerobic respiration and photosynthesis are interrelated because they are complementary processes. Photosynthesis in plants produces oxygen and glucose using sunlight, while aerobic respiration in animals and plants uses oxygen and glucose to produce energy, releasing carbon dioxide and water as byproducts. Essentially, the oxygen and glucose produced during photosynthesis are used as inputs for aerobic respiration, and the carbon dioxide produced during respiration is used as an input for photosynthesis.
What happens to the glucose that the plants produce during photosynthesis?
The produced glucose will become food for the plant.
What wavelength of light is the least effective in driving photosynthesis?
Green light is the least effective in driving photosynthesis because chlorophyll pigments absorb more strongly in the blue and red regions of the spectrum. This results in green light being poorly absorbed and utilized for photosynthesis in plants.
What gas is produced as a byproduct during photosynthesis?
the by product of photosynthesis is oxygen
whereas the by product of that of the plant respiration is carbondioxide.

What prevents leaves from drooping?
Leaves have a structure of cells and fibers that provide support and maintain their shape. They also have a system of veins that transport water and nutrients, which helps them stay upright. Additionally, the presence of turgor pressure inside the cells helps keep leaves rigid and prevents them from drooping.
How is auxin different from gibberellins and ethylene in terms of function?
Auxin is involved in cell growth and elongation, while gibberellins are involved in stem elongation, seed germination, and flowering. Ethylene regulates fruit ripening, leaf abscission, and senescence in plants. Each of these plant hormones has distinct functions in growth and development.
What are the mean source of energy for photosynthesis?
The primary source of energy for photosynthesis is sunlight. The light energy is absorbed by chlorophyll in plant cells and is converted into chemical energy in the form of glucose through a series of biochemical reactions. This process is essential for plants to produce their own food and release oxygen as a byproduct.
What are some ways by which plants can increase their rates of photosynthesis and transpiration?
Increasing the temperature of the reaction will always increase the rate, though the actual yield will depend on whether the reaction is exothermic or endothermic. Increasing the pressure of the... Read More
What is the type of energy that is stored in the form of food during photosynthesis?
when plants use photosynthesis plants use the light energy from the sun (and other ingrediants) and convert it into glucose which in some plants can be stored in fruits that we eat such as vegetables or if a animal eats said plant the animal breaks down the glucose and uses it as chemical energy to use throughout their daily activities or can be stored in things such as fat but to be used later on or can be harvested and eaten and broken down by other animals to be used; however, when this happens the predator dosn't get near as much energy so would have to eat more to get the same amount of energy due to the loss of energy but is still broken down the same way
Does photosynthesis and respiration both release energy?
Yes, it does release energy.
This is the entire purpose of respiration in animal cells, which is also called the Krebs Cycle on a cellular level. Glucose is broken down to create chemical energy for the cell in the form of ATP molecules, which can then be broken down to perform various metabolic processes within the cell. The waste products of this are CO2, expelled either from cell membranes or from exhalation as blood releases this waste gas into the lungs, and water, which can be retained by the cell or diffused out in the form of osmosis so the pressure or water within the cell does not become too great.
What types of organisms undergo photosynthesis?
all green plants (producers) & phytoplankton in water. Basicly all plants and trees that is why people are trying to save the trees otherwise there would be none for photosythisis to take place so we would have no oxygen so we would all die.
Does longan grow in the Philippines?
Yes, longan does grow in the Philippines. It is commonly cultivated in various regions of the country due to its popularity and favorable growing conditions.
What is the role synthase in photosynthesis?
Synthase enzymes are involved in the synthesis of ATP during photosynthesis. They play a crucial role in the conversion of light energy into chemical energy, which is essential for the plant to carry out various metabolic processes.
What molecule is split during the light reactions of photosynthesis of release oxygen?
Water molecules are split during the light reactions of photosynthesis to release oxygen. This process is known as photolysis, where water is broken down into oxygen, protons, and electrons in the presence of light.
Which organisms use the sun's energy to make their own food by the process of photosynthesis?
Plants, algae, and some bacteria use the sun's energy to convert carbon dioxide and water into glucose through the process of photosynthesis. These organisms are called autotrophs because they can produce their own food from sunlight.
Where inside the chloroplast does light reaction take place?
The light reactions of photosynthesis take place in the thylakoid membrane of the chloroplast. Here, light energy is captured by pigments and converted into chemical energy in the form of ATP and NADPH.
In which part of the plant does most of the photosynthesis take place?
Any part of a plant that is green can perform photosynthesis, its just that leaves have special adaptations to optimize its efficiency.
So plants with green stems can, plants with brown woody stems can't.
Why is light needed for photosynthesis?
Chlorophyll is the molecule that absorbs sunlight and uses its energy to synthesis carbohydrates from CO2 and water. This process is known as photosynthesis and is the basis for sustaining the life processes of all plants. Since animals and humans obtain their food supply by eating plants, photosynthesis can be said to be the source of our life also.
The energy plants have from water and light is converted from light energy to chemical bond energy.
Light is needed because the whole process won't work without light as light is in the equation carbon dioxide plus water equals glucose plus oxygen.
What are the starting substances in photosynthesis?
The starting substances in photosynthesis are carbon dioxide and water. Through the process of photosynthesis, these substances are converted into glucose and oxygen with the help of sunlight and chlorophyll.
How do scientists summarize the process of photosynthesis?
plants need photosynthesis to produce their own food,co2 enters air spaces through the stomata,this co2 enters cobines with H2O,light energy splits H2O molecules,H2O enters from xylem vessels,light is absorbed by pallisade,spongy,mesophyll and gaurd cells by chlorophyll,carbohydrates and oxygen are produced as by products
What advantage does a plant obtain by having molecules that act at different wavelengths?
Different wavelengths may be present at different times, or in different environments. If a plant is able to photosynthesise using light of many different wavelengths, it is able to continue to function in a range of situations - when other plants may not have been able to.
Which is a reactant in the process powered by sunlight hitting photosystem 2?
The reactant in the process powered by sunlight hitting photosystem 2 is water. In this process, water is split into oxygen, protons, and electrons when sunlight is absorbed by chlorophyll molecules.
How do you make a model of photosynthesis using modern technology?
You can create a model of photosynthesis using modern technology such as computer simulation software or bioinformatics tools. These tools can help you visualize and simulate the complex processes involved in photosynthesis, including the flow of electrons and synthesis of ATP and NADPH. Additionally, you can use 3D printing technology to create physical models of plant cells and chloroplasts to demonstrate the structures involved in photosynthesis.
