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.

How are photosynthesis and cellular respiration different?

Photosynthesis: occurs in plants and some bacteria. only occurs in the presence of sunlight/UV light occurs within the chloroplasts. requires chlorophyll uses water, light energy and carbon dioxide produces oxygen and glucose (which are the reactants of cellular respiration) captures light energy to store as chemical energy builds up the plant's energy stores chemical formula is 6CO2 + 6H2O (+ light energy) C6H12O6 + 6O2 is an anabolic reaction, i.e. simple molecules are built up into complex ones occurs in two phases: the light and dark reactions uses NADP to...

What is photosynthesis?

Photosynthesis (photo = light and synthesis = to make) is the process plants use to change carbon dioxide and water into sugar using sunlight. This sugar, glucose, is their food, and the process gives off oxygen. Photosynthesis is the conversion of light energy into chemical energy by living organisms. The raw materials are carbon dioxide and water. The energy source is sunlight, and the end-products include glucose and oxygen. It is arguably the most important biochemical pathway, since nearly all life depends on...

How does cloudy weather affect photosynthesis?

Photosynthesis is the process of taking water and light and turning it into energy in the form of sugar. So, if plants don't have enough light, they wont be able to prodce sugar. They still get some light when clouds are around, but not enough for them to be able to create a lot of the product. ********* Light is a limiting factor in photosynthesis during cloudy weather. ...

What happens because of photosynthesis?

Photosynthesis is source of all food which is used by consumers . Initial product of photosynthesis are triose which are converted to hexoses , sucrose , starch and cellulose . All these carbohydrates are direct source of food and energy for animals and Fungi . No animal life would be possible without photosynthesis . Oxygen is by product of photosynthesis . It is utilized by all aerobic organisms during respiration . ...

What organelles contain chlorophyll and other pigments involved in photosynthesis?

Chlorophyll and other pigments of photosynthesis are mainly in chloroplasts. There are also pigments such as carotenoid present in chromoplasts. Photosynthetic pigments are also found in cyanobacteria. ...

What are some synonyms for photosynthesis?

Photosynthesis is the synthesis of using sunlight as the source of energy and with the aid of chlorophyll and associated pigments. Also, photo means light from the loan-translation of German. A synonym for photosynthesis could be light construction. Carbon assimilation is synonym for photosynthesis ...

Does photosynthesis not occur in absence of light?

Photosynthesis can occur without sunlight but only for a certain period as the sunlight originally supplies the energy that is needed to be converted. Without the original source for an elongated period photosynthesis would eventually stop. ...

What plant organs absorb light?

Any part of the plant that is green will have cells that contain chloroplasts which are responsible for capturing light and converting it to chemical energy. ...

Do all living organisms undergo photosynthesis?

No, not all living organisms undergo photosynthesis. Only phototrophs (photosynthetic autotrophs) such as plants, algae, and many forms of photosynthetic bacteria undergo photosynthesis. All other organisms live by eating autotrophs or other organisms that have eaten autotrophs; these organisms are heterotrophs. There are a few specialized organisms (which may live where no light shines) that use a process called chemosynthesis to get their energy; these organisms are called chemotrophs. ...
Asked in Photosynthesis

Why is photosynthesis important to plants and animals?

The process of photosynthesis provides plants with the food and energy they need to grow. The animals subsequently eat them at various stages of their growth. Photosynthesis is the driving force of primary producers One of the byproducts of photosynthesis is oxygen (both terrestrial and marine plants), which we breath. Without photosynthesis the oxygen levels in the atmosphere would not be replenished. ...

Why does chlorosis occur in plants?

Plants have chloroplasts which contain chlorophyll, and if there is decrease in chlorophyll due to less availability of magneseium or nitrogen in the soil, then this results in Chlorosis. ...

What happens to the rate of photosynthesis if the stomata becomes larger?

The rate may increase as the exchange of CO2 and O2 becomes easier, but the rate of transpiration (water vapor being lost to the atmosphere) will increase. With this trade off, there is an optimal size for the stomata to be for the given conditions. ...

When you burn petrol what gases are formed?

Petrol is a hydrocarbon ( made of hydrogen and carbon). When it burns in plentiful of oxygen it form carbon di oxide gas and water vapours. If oxygen is in limited supply carbon monoxide is formed instead of carbon dioxide. Petrol sometimes contains impurities of Nitrogen and Sulphur. When petrol burns these elements combine with oxygen to make oxides of nitrogen and sulphur dioxide ( All of which are gases). ...

Can photosynthesis occur under water?

Yes, although only when the water is clear and shallow enough for sunlight to travel through the water to plants like algae helping them survive. However, some algea species are able to live further down and photosynthesize. Rhodophyta, red algea, is able to photosynthesize because of a pigment called phycoerythrin which allows them to absorb more blue light wavelengths. The fact that it can absorb blue light is important these shorter wavelengths are able to penetrate into the water further. ...

How does air help us in photosynthesis?

Plants perform photosynthesis by taking in water and the carbon dioxide we breathe out, and turning them into a mixure called glucose. 'Air' or oxegyn is a byproduct of photosynthesis. So plants and us are, in essence, dependent on each other for life. ...

Can leaves that are not green make food?

Yes, leaves do not have to be green to photosynthesize and make food. The green is caused by chlorophyll, the most common and the most efficient, but not the only, compound that can extract energy from sunlight. Other pigments that can photosynthesize include cartenoids and phycobilins, and non-green leaves that photosynthesize range from brown and red seaweeds to red or yellow lichens and purple-leaved plum trees. ...

How does light direction affect plant growth?

Plants need light and they will grow towards where they receive an optimal amount; plants will face where the light is. You can experiment on your own by growing your own plant and using a desk lamp as the light source. As the plant grows, it will lean towards and face the light source directly. ...

Asked in Biology, Genetics, Photosynthesis

What waste is generated when cells make ATP?

It depends on the type of respiration taking place. Lactic acid or ethyl alcohol will be produced if it is in anerobic (O2 is not present) conditions while water will be produced as a waste in aerobic (O2 present) conditions. In the process, CO2 is also produced no matter if it is anerobic or aerobic. ...

Asked in Photosynthesis

Is carbon dioxide released by photosynthesis?

Plants absorb carbon dioxide by photosynthesis. They release carbon dioxide, usually at night, through respiration. Photosynthesis is a process that uses the energy of light (photo-) to fuel the conversion of carbon dioxide and water into sugars that can then be converted into plant material (-synthesis) as well as releasing oxygen. In the process of converting the sugars created by photosynthesis into other plant material, plants consume some oxygen and release carbon dioxide. This is particularly noticeable at night or when light is low...
