Photosynthesis

Plants, algae, and cyanobacteria are examples of organisms that can undergo both photosynthesis and cellular respiration. During the day, they perform photosynthesis to produce energy from sunlight, and at night or during times of low light, they switch to cellular respiration to generate energy from stored carbohydrates.

Photosynthesis is the making of a simple sugar that is food for a plant. A plant needs water, nutrients, sunlight, and and the Carbon Dioxide in air. If there isn't one of these things, a plant will not survive long.

The primary site of photosynthesis in plants is the chloroplasts. These organelles contain chlorophyll, the pigment that absorbs light energy needed for the process of photosynthesis to occur. Within the chloroplasts, photosynthesis takes place in the thylakoid membranes where light reactions occur and in the stroma where the Calvin cycle (dark reactions) take place.

In photosynthesis, light energy is captured by chloroplasts and used to knock an electron from watermolecules. The freed electrons are used to generate glucose sugars (used for the plant's growth and survival) from carbon dioxide, with water and oxygen as byproducts.

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.

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.

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.

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.

No, we need oxygen. But after we inhale the oxygen, the exhale is mostly carbon dioxide.

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.

two things produced at the end of photosynthesis are glucose and oxygen

During photosynthesis, plants convert carbon dioxide into glucose (sugar) and oxygen. This process requires sunlight to produce energy for the plant.

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.

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.

plants inhale carbon dioxide and exhale oxygen

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.

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.

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.

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.

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.

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.

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!

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!

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.
