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 food chain starts without photosynthesis?

A food chain that starts without photosynthesis would involve organisms relying on chemosynthesis instead. For example, in deep ocean ecosystems near hydrothermal vents, chemosynthetic bacteria use chemicals from the vent fluids to produce energy, which is then consumed by other organisms in the food chain.

What is the name of a chemical that aids in photosynthesis?

The green colored chemical that traps light is called Chlorophyll.

What role do the electrons released play in photosynthesis?

In photosynthesis, the electrons released during the light-dependent reactions play a crucial role in converting light energy into chemical energy. When light is absorbed by chlorophyll, it excites electrons, which are then transferred through a series of proteins in the thylakoid membrane, known as the electron transport chain. This process generates ATP and NADPH, energy-rich molecules that are essential for the subsequent light-independent reactions (Calvin cycle) where carbon dioxide is fixed into glucose. Thus, the electrons are vital for powering the entire photosynthetic process.

How the reproduction takes places in hibiscus plant?

Reproduction in Hibiscus plants occurs via sexual reproduction. The Hibiscus flower is bisexual and contains both the ovary and stamen. The pollen from the stamen is cross-pollinated and deposited onto the stigma. The pollen travels through the pollen tube to the ovary.

What is a generalized equation for photosynthesis?

The general equation of photosynthesis is carbon dioxide + water ---light energy ---> oxygen + glucose This can also be written as carbon dioxide + water (+ light energy) ---> oxygen + glucose

Which statement describes how photosynthesis and cellular respiration are interrelated?

The statement " All the products of Photosynthesis i.e Sugar, Oxygen are the reactants of Cellular Respiration , and all the products of Cellular Respiration i.e Carbon Dioxide are the reactants of Photosynthesis ." ,describes that the two most integral metabolic processes i.e Photosynthesis and cellular respiration are inter-related .

The three things that enter the plant during photosynthesis are?

The three main things that enter the plant during photosynthesis are water, carbon dioxide, and sunlight. Water is absorbed through the roots, carbon dioxide is taken in from the air through small openings in the leaves called stomata, and sunlight is absorbed by the chlorophyll in the plant's cells.

What are the Raw materials and the products of respiration?

Raw materials: glucose and oxygen

Products: carbon dioxide and water

And, of course, energy.

Which gas is needed by plants for respiration?

Oxygen is the gas that animals use in respiration. Plants use both oxygen and carbon dioxide. (This is assuming you mean cellular respiration.)

What happens to the water and sunlight during photosynthesis process?

During photosynthesis, water molecules are split into oxygen, protons, and electrons in a process known as photolysis, releasing oxygen as a byproduct. Sunlight is absorbed by chlorophyll in the chloroplasts of plant cells and provides the energy needed to convert carbon dioxide and water into glucose and oxygen.

Which phrase best describes the electron transport chain in photosynthesis?

Yes. Photosynthesis involves the transfer of electrons. Photosynthesis causes a chemical change. All chemical changes involve either the transfer of electrons or a change in the configuration of electrons. No other way exists to make a chemical change.

Can oxygen be made artificially?

yes, water can be made by artificial methods.infact what ur brain can imagine,it can exist no matter what a great,ugly,funny or unrealistic thing ur brain has imagined.

now how can we prepare water by artificial methods or in our laboratory by different methods.one of them is fuel cell.it is a device which can convert heat energy produced by combustion of hydrogen and oxygen gases and water is a byproduct of this process.if u want to discuss it deeply pls mail to deepakaeromodel@gmail.com or discuss here

Can mushrooms do photosynthesis?

Mushrooms are a type of fungus and they are used for spreading their organism's spores. Fungi are absorptive heterotrophs and obtain their food from their environments. They do not go through photosynthesis.

How many carbon dioxide molecules are needed to produce 3 molecules of glucose?

Each glucose molecule contains 6 carbon atoms. Thus we need 18 molecules of CO2 to make 3 molecules of glucose.

What are two substances made in photosynthesis?

sugar and oxygen

I_disagree_it_is_Glucose.">I disagree it is Glucose.

sugar and oxygen and also glucose this answer is right !!!

Ya bud. Sugar and Oxygen are Glucose.

What is the function of the light independent reaction of photosynthesis?

To provide ATP and NADPH to drive the next part of photosynthesis, the Calvin Cycle (AKA Dark Reaction, Light Independent Reaction). Light reactions also produce oxygen gas as a byproduct.

What is the simplest equation of photosynthesis?

i think that it is just:

carbon dioxide + water --> oxygen + glucose

(above the arrow put light energy && below the arrow put chlorophyll)

the symbol equation is:

6CO2 + 6H2O --> 6O2 + C6H12O6.

hope this helps :)

A reactant in photosynthesis that is a liquid?

Water is a reactant in photosythesis that is a liquid.

Which organisms undergo photosynthesis in sea?

Yor mom goes down there with a HUGE flashlight and does it. sea plants that are close enough to the surface of water get sunlight from the sun and the ones far enough from the surface do not need very much/any sunlight.
