Photosynthesis

nope. only in the chloroplast. in that there are two cycles, the light reaction and the Calvin cycle

Light reaction

light is taken in the plant

water from the roots is broken down

oxygen is released from the plant leaves

ATP and NADPH (a high energy electron carrier) is produced (carries hydrogen)

Calvin Cycle

CO2 is taken in

ATP is used as energy

NADPH is used to lower ativiation energy

(after the calvin cycle, NADPH become NADP+)

With the help of the enzyme RuBisCo this reaction takes place.

CO2 + ribulose biphosphate ( a 5 C sugar ) -> 2(3-phosphoglycerate)( 3 C sugar)

This happens in the Calvin cycle. With CO2 and RuBP a reaction takes place with ATP and NADPH to do a complicated bit of arranging with the three CO2's coming into the cycle. Six of the 3-phosphogylcerates are made, but only one the product of one cycle and the rest go back into the cycle. The 3 carbon sugar then can be used to build glucose or used in the mitochondria for energy.

Van Helmont conducted research related to plant nutrition and growth, particularly his famous willow tree experiment where he observed the uptake of water by plants. He is also known for his contributions to the idea of spontaneous generation and for coining the term "gas" in the context of chemical reactions.

6CO2 + 6H2O ->(+ photons of light ) -> C6H12O6 + 6O2

This equation says, carbon dioxide gas plus water ( + light ) equals glucose, a sugar, and oxygen gas.

So, yes, photosynthesis, the equation above, produces sugar.

That is correct. Photosynthesis is the process by which plants and other organisms convert sunlight into energy and produce oxygen as a byproduct. This oxygen is then released into the atmosphere, where it can be used by other organisms for respiration.

1. Photosynthesis is important because oxygen is released as a byproduct. We need that oxygen to survive.

2. Photosynthesis helps get rid of the carbon dioxide in the air. Carbon dioxide, as you may probably know, is necessary for this process to occur.

The majority of the water is used to make a sugary food called glucose, that is used to feed the plant. The excess glucose is stored in the roots of the plant to provide the plant with nutrients in the spring. The excess water evaporates from small pores within the leaf. That is why greenhouses are often foggy.

The small amount of excess carbon dioxide is stored within the plant and is released when the plant dies and decomposes.

The equation for photosynthesis is: 6CO2 + 12H2O → C6H12O6 + 6O2 + 6H2O

This could be simplified to (and is usually seen as): 6CO2 + 6H2O → C6H12O6 + 6O2.

From the equations above, it could be seen that sunlight is not a reactant in photosynthesis. Reactants are substances that takes part in and undergoes change during a reaction. Sunlight does not; hence sunlight is not a reactant in photosynthesis.

Plants require nitrates for use with sugar to produce protein. Both nitrates and phosphates are used to create DNA, especially phosphate as it makes up the 'backbone' of the DNA. Phosphate is also needed to create ATP, or usable energy.

In C3 plants, photosynthesis occurs throughout the leaf, while in C4 plants, photosynthesis occurs in the inner cells. The photosynthesis in C3 plants is more efficient compared to the one in C4 plants.

The coconut seeds have fibrous outer covering in order to help them float in water for dispersal. Whereas the tiger's nail seed has hooks/spines which help them cling to animals for dispersion.

Plants..There the only living thing that make there own food and they use the suns energy to make their own food which provides us and animals with oxygen that we breath in and food that we eat ..eg fruits...

There is no role of oxygen in photosynthesis. Oxygen is used as the terminal electron acceptor during respiration. Oxygen is the by-product of a water molecule breaking down in the very beginning of photosynthesis to supply photosystem II with electrons.

Aristotle was a Greek scientist who thought that plants ate soil and sucked it up through their roots. Most people believed this until the 17th century. In the 17th century, a scientist called Jan van Helmont tested Aristotle's theory. He measured the masses of a small tree and some soil in a pot. He planted the tree and watered it for 5 years In van Helmont's experiment the mass of the soil did not go down much (0.06kgs/ 0.132lbs) but the mass of the tree went up a lot (74.47kg/163.834lbs). This showed that Aristotle's theory was wrong. Van Helmont suggested that the tree got all of its food from water. In 1782, Jean Senebier showed that plants need carbon dioxide gas from the air and suggested that plants only use this gas to make food. In 1804, Nicholas de Saussure did van Helmont's experiment again, but he carefully measured the amounts of carbon dioxide and water he gave to the plant. He showed that both carbon dioxide and water are needed.

it is only needed for photosynthesis as we humans do not get our energy from light ( think about it we still breath when it is dark don't we)

Carbon dioxide serves as the source of carbon atoms that are fixed during the Calvin cycle of photosynthesis. These carbon atoms are used to build sugars and other organic molecules essential for plant growth and metabolism. Without carbon dioxide, plants would not be able to produce these vital compounds through photosynthesis.

During photosynthesis, carbon dioxide and water are converted into glucose and oxygen in the presence of sunlight and chlorophyll. The overall process can be summarized as: carbon dioxide and water react to form glucose and oxygen with the help of light energy.

The chemical energy made by photosynthesis is in the form of glucose, a simple sugar molecule. This glucose can then be used by plants as a source of energy for growth and maintenance or stored for later use.

The tissue system responsible for photosynthesis in the plant body is the mesophyll tissue, located in the leaves. This tissue contains chloroplasts, where photosynthesis occurs, converting light energy into chemical energy that the plant can use for growth and development.

Adenosine triphosphate (ATP) is the molecule that stores and releases energy for cellular processes. It is commonly referred to as the "energy currency" of the cell because it carries energy in its phosphate bonds that can be readily used by cells. When ATP is broken down into adenosine diphosphate (ADP) and inorganic phosphate, energy is released for cellular activities.

the equasion for photosynthesis: 6co2+6h2o interacting with sunlight and nutrients=c6h12o6+6o2

The cell organelle responsible for photosynthesis is the chloroplast. It contains chlorophyll, a pigment that captures sunlight and converts it into chemical energy through the process of photosynthesis. The chloroplast is green in color due to the presence of chlorophyll.

when we talk about (fate) we mean thoes thngs that when photosynthesis occur happes. They are:

Glucose is converted to starch and temporaly stored in the day.

The triose phosphate of the Calvin cycle can be synthesised into hexose sugars eg,glucose and fructose.The glucose may be polymerised to give starch for storage or maybe made into cellulose which makes up over 50% of the cell wall.

The products of photosynthesis are oxygen and glucose.
