Photosynthesis

From the soil, the root of the plant obsorb mineral which help the plants to grow and obsorbs water which is restor in the soils.

ATP and NADHP

Two conditions necessary for photosynthesis are sunlight - to provide the energy needed for the process, and chlorophyll - a pigment that captures light energy for use in photosynthesis.

Oxygen is produced as a by-product of photosynthesis.

the calvin cycle

Carbon Dioxide + Water --> Glucose + Oxygen

CO2 + H2O --> C6H12O6 + O2

Balancing the equation, it becomes:

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

Note that the reactions also require light and energy (usually written in smaller letters above or below the arrow signs).

The balanced equation is the one you should write during exams, unless they ask you otherwise (which would be very odd).

Most photosynthetic organisms that do not contain chloroplasts are bacteria. Some examples would be green sulfur and non sulfur bacteria which use chlorosomes. Chlorosomes contain light harvesting pigments known as bacteriochlorophylls. Cyanobacteria do not contain chloroplasts but use chlorophyll A and phycobilin photosynthetic pigments.

Sunlight

sunlight i absorbed in chloroplasts.

light intensity effects the rate of photosynthesis

The right temperature is needed or the enzymes become denatured

Water and carbon dioxide are also needed

Nitrogen is needed for growth

Phosphorus is needed for making root tissues and respiration

Potassium is for respiration and photosynthesis

carbon dioxide + water + light = sugar and oxygen

Yes, wheat plants do use photosynthesis to convert sunlight into energy. Photosynthesis occurs in the chloroplasts of wheat leaves, where chlorophyll molecules capture sunlight and use it to produce glucose, which is then used as an energy source for the plant.

The stomata are small openings in the bottom of a leaf that absorb carbon dioxide which is then combined with sugar to make glucose or sugar for the plant to turn into energy to carry out specific functions.

The question is in regard to leafs, as my resident teenager just had the same homework. It is poorly worded, as it should be asking, "Why does a leaf exhibit a low oxygen flow when illuminated only by green light" ...or something along those lines.

In simple terms, chlorophyll feeds the plant by converting light and CO2 into 'food' and O2. A lack of oxygen means that this chemical reaction isn't occurring. Why? A lack of light. The chlorophyll is green because it primarily reflects green and yellow light, meaning that it absorbs (and uses) the reds and blues. Shining a green light on a plant is almost the same as not shining any light on it.

Chemosynthesis gets its energy from oxidation of inorganic substance, photosynthesis gets its energy from light.

Chemosynthesis could occur just about anywhere there are enough suitable chemicals to oxidize [metabolize], while photosynthesis could occur only when there is sufficient light.

The water splitting step in photosynthesis is critical as a source of hydrogen ions (protons). These provide essential chemical energy to drive later chemical reactions.

The mesophyll is the ideal site for photosynthesis in the leaf because it contains a high concentration of chloroplasts, where photosynthesis takes place. It also has a large surface area for light absorption and a network of air spaces that facilitate gas exchange for photosynthesis. Additionally, the mesophyll cells are positioned close to the leaf surface, allowing for efficient light penetration for photosynthesis.

The palisade mesophyll cells, located in the upper layer of the leaf, are the most active in photosynthesis. They contain a high concentration of chloroplasts, where photosynthesis takes place, and are positioned to receive the most light for energy production.

Energy produced in photosynthesis is put into usable form through cellular respiration. They are both ways cells gain energy. In photosynthesis, cells use solar energy to produce glucose and oxygen from carbon dioxide and water. In cellular respiration, cells make ATP (which is used as energy by the cells) and consume oxygen during the conversion of glucose to carbon dioxide and water.

Photosynthesis does not involve nitrogen. It is used by plants to make sugar, a chemical that does not include nitrogen. Also note that the air is composed mostly of nitrogen; it would hardly be necessary for plants to make nitrogen.

The products of photosynthesis, such as glucose and oxygen, are used by other organisms as a source of energy. Glucose is a key source of energy for many organisms, including plants, animals, and bacteria. Oxygen is used by animals for respiration to produce energy.

1 Light and water are absorbed

2 Water splits into hydrogen, oxygen, and electrons

3 The electrons get excited by the light energy and shoot up to the next level (the electron acceptor)

4 the electron comes back down and produces ATP

5 The electrons get excited again and shoot up to the electron acceptor

6 they come down and make NADPH

7 ATP and NADPH (making a sugar that is not yet glucose, but G3P) from the light reactions provide energy that are used to convert G3P to glucose and other materials
