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.

What do plants use during photosynthesis to make sugars and starches?
Plants use sunlight, carbon dioxide, and water during photosynthesis to make sugars and starches. Sunlight is captured by chlorophyll in the plant's cells, which initiates the production of glucose (sugar) and starch through a series of chemical reactions.
What group includes some members that can carry out photosynthesis bacteria or a viruses?
Bacteria such as cyanobacteria are able to carry out photosynthesis, while viruses lack the cellular machinery to perform photosynthesis. Viruses are obligate intracellular parasites that require a host cell to replicate and do not possess the cellular machinery needed for photosynthesis.
Can All algae except for diatoms can conduct photosynthesis?
No, all algae have the capability to conduct photosynthesis, including diatoms. Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose.
Where does photosynthesis not occur in a leaf?
Green plants use a pigment called chlorophyll to photosynthesise. Chlorophyll absorbs strongly in the red end of the visible spectrum, and reflects green light, which is why it looks green.
Some plants, and many other photosynthetic organisms, use pigments other than chlorophyll to capture sunlight. These other pigments, mainly xanthophylls and bacterophylls, reflect various parts of the spectrum. For example xanthophylls reflect yellow light while bacterophylls reflect purple light. Many photosynthetic organisms use more than one pigment, each reflecting different parts of the spectrum, and collectively capturing a wide range of the visible part of the sun's energy. These plants may look purple or even almost black.
Is carbon dioxide needed in photosynthesis?
No, we need oxygen. But after we inhale the oxygen, the exhale is mostly carbon dioxide.
What is the main purpose of respiration is to produce?
The main purpose of respiration is to produce energy in the form of ATP (adenosine triphosphate) by breaking down glucose molecules in the presence of oxygen. ATP is the primary energy source used by cells to carry out their functions.
What 2 things are produced at the end of the photosynthesis process?
two things produced at the end of photosynthesis are glucose and oxygen
What does a plant convert carbon dioxide into during photosynthesis?
During photosynthesis, plants convert carbon dioxide into glucose (sugar) and oxygen. This process requires sunlight to produce energy for the plant.
What products are created by the process of photosynthesis?
PHOTOSYNTHESIS is the process in which green plants take in carbon dioxide from the air and absorb water from the soil.They conver it into oxygen and glucose with the help of energy derived from the sun. They are able to do this because of the green pigment they possess called CHLOROPHYLL. In the end, the plands consume the prepared glucose. Oxygen is released/created in the process.
What chemical must be present in a cell for it to be able to carry out photosynthesis?
Chlorophyll is the chemical that must be present in a cell for it to carry out photosynthesis. It is a pigment found in chloroplasts that absorbs light energy and allows the plant to convert sunlight into chemical energy.
What do plants inhale and exhale during photosynthesis?
plants inhale carbon dioxide and exhale oxygen
How much can photosynthesis produce every day?
How much WHAT?
It can't produce ANY brownies, but can produce energy storing molecules in plants
The energy synthesis would vary depending on the size, and type of plant, it's overall health, the availability of CO2 and water, and the amount & intensity of the light it was exposed to.
Does photosynthesis occurs in plants having red and brown leaves?
Yes. Plants with leaves with colours other than green still contain chloroplasts (which are the part of the plant which does the photosynthesis). The reason the leaves aren't green is because other colour pigments are more prominent and they camouflage the green of the chloroplasts... but they do certainly still contain chloroplasts and undergo photosynthesis.
What high energy molecules are used in photosynthesis?
NADPH and ATP are produced by the light reactions. The ATP is a high energy molecule produced by photophosphorylation while the NADPH is produced at the end of the electron transport chain.
What will happen if the stem is removed from the plants?
If they are removed before or during early germination the seedling will probably die, if they are removed well into germination or after germination then the survival rate of the plant increases as the food in the cotyledons was almost already consumed.
Does carbon dioxide undergo oxidation during photosynthesis?
No, carbon dioxide undergoes reduction during photosynthesis, where it is converted into glucose by accepting electrons and hydrogen ions. This process involves the opposite of oxidation, which is reduction.
B noncyclic photophosphorylation requires electrons that are obtained by the splitting of water. The process involves the flow of electrons through both photosystem I and photosystem II to generate ATP and NADPH for the light-independent reactions of photosynthesis.
Does photosynthesis add oxygen to the atmosphere?
Yes, photosynthasis does add oxygen to the atmosphere becaause the organisms (plants) developed the ability to photosynthasise. By taking in carbon dioxide and releasing oxygen.
What is photosynthesis in a yucca plant?
For photosynthesis in a Yucca Plant, the plant must be watered at least 5 times a day. The Yucca Plant is very sensetive. If you cut it, it will not grow, but it will die effective in about 1,2,3, or 4 weeks. I hope I helped you out!

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.
