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.

When plants undergo photosynthesis do they produce oxygen?

Well, it does! they deal with oxygen in a photosynthesis process! like this

carbon dioxide + water > glucose + oxygen! and there is suppose to be another part right there in the middle of water and glucose!^ it is light that's where sun comes in!

Can you tell from these absorption spectra whether red light is effective in driving photosynthesis?

No, absorption spectra provide information on the wavelengths of light that are absorbed by a pigment, but they do not inherently indicate the effectiveness of that light in driving photosynthesis. Red light is typically absorbed by chlorophyll, making it effective in photosynthesis, but further experiments like action spectra or photosynthetic rate measurements are needed to confirm its effectiveness.

What enters through stomata in photosynthesis?

The raw materials of photosynthesis that enters the leaf through the stomates or stomata is H2O or water

Why can plant perform photosynthesis but animals cannot?

Plants contain chloroplasts with chlorophyll, which allows them to capture light energy and convert it into chemical energy. Animals do not have chloroplasts and lack the necessary cellular machinery to carry out photosynthesis. Instead, animals obtain energy by consuming other organisms.

What is the site of the majority of photosynthesis in leaf?

The leaf contains palisade cells which have lots of chloroplasts. Chloroplasts are the actual site of photosynthesis, as they contain a chemical called chlorophyll which must be present during photosynthesis.

Where did many of Britain raw materials come from?

During the 18th and 19th centuries, many of Britain's raw materials came from its colonies in North America, the Caribbean, Africa, and Asia. These resources included goods such as cotton, sugar, tea, and metals like iron and copper, which were vital for Britain's industrial development.

Where does the released oxygen come from in photosynthesis?

The released oxygen in photosynthesis comes from the splitting of water molecules during the light-dependent reactions in the thylakoid membrane of the chloroplasts. Water molecules are broken down into oxygen, protons, and electrons, with oxygen being released as a byproduct.

Where does respiration take place in amoeba?

The entire surface of the amoeba is its respiratory surface. It is always wet because the amoeba lives in water, and oxygen continually diffuses in and carbon dioxide continually diffuses out.

Do truffles photosynthesis?

No, truffles do not photosynthesize. Truffles are fungi that grow underground in a symbiotic relationship with tree roots, obtaining nutrients from the trees rather than from sunlight like plants do.

What do photosynthesis and chemosynthesis have that are different?

chemosynthesis is the process by which an organism forms carbohydrates using chemicals rather than light, as an energy source and photosynthesis is the process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as energy source.

Where do electrons come from and how it gains energy during the light reaction?

They come from Photosystem ll. Photosystem ll gets them by ripping the electrons off of water by a process called photolysis.

Electrons gain energy first in Photosystem ll, then later in photosystem l, through the absorption of energy from light.

What effect does a rise in the cost of machinery or raw materials of raw materials have on the cost of a good?

A rise in the cost of machinery or raw materials typically leads to an increase in the production cost of a good. This increase in production cost is often passed on to consumers, resulting in a higher price for the final product.

What is produce when water molecules are split to produce the electrons needed to replace those lost by photo system 2 during photosynthesis?

Oxygen and H+

the overall equation is,

2H2O ----> O2 + 4H+ + 4electrons

electrons as you know are taken up by PSII, H+ go on to form NADPH by combining with NADP+ at the end of PSI and O2 is a by product of photosynthesis

What 2 cell parts does cellular respiration take place?

mithochondrial matrix and thylakoid

or... (apex answer---->)mitochondrial matrix and cristae :)

<3 kymmie..

apex all the way :)

What is the stages of photosynthesis and list the starting molecules and ending molecules of each?

  • One stages Light Dependent: started with water (H20) and end with waste of oxygen then product oxygen.
  • Two states Calvin Cycle: started with Co2 and end with Glucose then product a phosphate group and NADP+.

What benefit do you get from the oxygen that the plant makes?

The benefit that we get from plants is the fact that they change carbon dioxide into oxygen. Of course, our bodies don't need pure oxygen, if we inhaled pure oxygen we would suffocate, but carbon dioxide is a waste product that our body creates that is completely useless to us.

What are the raw materials of a bulletproof vest?

"Bullet proof glass" is not a single thing, but a class of building materials that are composite in nature (several layers of differing thickness and materials).

Generally, the layers of ballistic glass include glass laminate, polycarbonate, or acrylics bonded with polyvinyl butyral, polyurethane or ethylene-vinyl acetate.

What event contributes directly to the creation of a proton gradient across the thylakoid membrane?

The flow of electrons through the photosynthetic electron transport chain contributes directly to the creation of a proton gradient across the thylakoid membrane. As electrons move through the chain, they pump protons from the stroma into the thylakoid lumen, generating the proton gradient used for ATP production during photosynthesis.

What are the products formed during the photosynthesis?

The main goal of photosynthesis is to produce chemical energy that the plant can use. In the process, carbon dioxide and water are also produced.

What enters through leaf pores and required for photosynthesis?

Carbon dioxide enters through leaf pores, known as stomata, and is required for photosynthesis to occur. Carbon dioxide is one of the raw materials needed by plants to produce glucose and oxygen during photosynthesis.

Why are the products of photosynthesis so important for the entire food chain?

Without it, you would die. cuz plants use photosynthesis to survive and make food for themselves. then animals eat the plants. and then we eat the plants and the animals that eat the plants. so if plants died, so would the animals that eat plants. and then when we dont have anymore plants and animals to eat... we go dead. :(

How do polytunnels affect the rate of photosynthesis?

By using greenhouses and polytunnels ( large greenhouse made of plastic) to control the levels of the limiting factors. It is useful, as it allows you to grow fruit which normally doesn't grow in cold climates in the UK

What is the presence of chlorophyll in plants?

cholorophyll is a green pigment in the chloroplasts in a plant cell. It enables photosynthesis to take place. Photosynthesis is the process that converts carbon dioxide and water using the suns energy into oxygen and glucose. This glucose is needed to keep the plant alive and give it energy to grow and respire. The plants will stretch them selves up to the sunlight.

So chlorophyll is necessary for providing energy to the plant. Photosynthesis also puts oxygen into the atmosphere which we as humans need to survive and it uses carbon dioxide.

Hope this answer was ok.

How are the two stages of photosynthesis the light reactions and the Calvin cycle dependent upon each other?

Photosynthesis' products are the same as the reactants of cellular respiration. In other words photosynthesis makes what cellular respiration uses.

What three ingredients do plants use to make sugar during photosynthesis?

Plants use carbon dioxide, water, and sunlight to make sugar during photosynthesis. Carbon dioxide is absorbed from the air, while water is taken up by the roots from the soil. Sunlight provides the energy needed to drive the process of photosynthesis.
