What happens to carbon during photosynthesis?

Carbon dioxide is converted into organic compounds, especially sugars, using the energy from sunlight and water.

What raw materials are needed by plant for photosynthesis?

Plants need water, carbon dioxide, and sunlight to carry out photosynthesis. Water is absorbed from the soil through the roots, carbon dioxide is taken in from the air through tiny pores in the leaves called stomata, and sunlight is captured by chlorophyll in the chloroplasts of the plant cells.

Where in the cell does light independent reactions take place?

Light-independent reactions, also known as the Calvin cycle, take place in the stroma of the chloroplast. This part of the chloroplast surrounds the thylakoid membranes where the light-dependent reactions occur. In the stroma, carbon dioxide is fixed and converted into glucose through a series of enzymatic reactions.

How does photosynthesis maintain balance between oxygen and carbon dioxide in the environment?

Photosynthesis helps to balance oxygen and carbon dioxide in the air because plants produce oxygen through photosynthesis, this therefore goes into air which humans breathe in. We breathe out carbon dioxide and the plants needs carbon dioxide, so therefore the levels of carbon dioxide and oxygen are balanced in the air.

Why is the dark reactions called a cycle?

RuBP made during the dark reaction is used to start the reaction again. novanet.

What are photosynthesis and photography have in common?

They both get energy from inorganic materials. Photosynthesis uses sunlight and chemosynthesis uses inorganic compounds. Chemosynthesis is the process by which certain bacteria convert carbon dioxide and water into carbohydrates using inorganic compounds for energy. Photosynthesis uses carbon dioxide, water and light to make oxygen and glucose.

What are the roles of chloroplast in photosynthesis?

The chloroplast is where photosynthesis occurs. There are structures inside the chloroplast called thylakoids. These thylakoids are membranes with special proteins on them that carry out the light reactions of photosynthesis. These membranes are stacked (these stacks are called grana) in order to increase their surface area for the light reactions. The light reactions are responsible for producing NADPH and ATP which will be used for the Calvin cycle. Between the membranes of the chloroplasts and the thylakoid membrane lies the stroma. Here is where the Calvin cycle takes place. It is responsible for producing glucose from a series of chemical reactions. Essentially, the chloroplast is responsible for carrying out photosynthesis which converts light energy into usable chemical energy for most life on Earth.

How do plants capture light energy for used in photosynthesis?

Plants capture light energy through pigments such as chlorophyll, which absorb light, particularly in the red and blue wavelengths. This light energy is used to drive the process of photosynthesis, where plants convert carbon dioxide and water into glucose and oxygen. The captured light energy is converted into chemical energy stored in the form of sugars.

What is the by product made in photosynthesis?

The byproducts of photosynthesis are oxygen and glucose. These are made when the processes known as the Kalvin Cycle and the Krebs Cycle.

What moves the sugars produced by plants?

Sugars produced by plants are move through a process called translocation. This process involves the sugars being transported through phloem vessels, which are specialized tubes that transport nutrients within the plant. Energy for this movement is provided by the plant through various mechanisms such as active transport and pressure gradients.

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 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.
