Photosynthesis

The cuticle of a leaf is a waxy, water-repellent layer that helps reduce water loss through transpiration, allowing the leaf to retain more water for photosynthesis. By preventing excessive water loss, the cuticle helps maintain proper hydration levels within the leaf, which is essential for efficient photosynthesis to occur.

a product of photosynthesis is oxygen .well, plants use oxygen and sunlight to

make food. another thing is that the food is made in the chloroplasts in the

palisade layer of cells.

the light reaction consist of two major steps :

1.)harvesting of energy from sunlight or light energy by chlorophyll molecules ; and

2.)conversion of light energy into chemical energy in adenosintriphosphate 9atp)and nicotinamide adenine dinucleotide phosphate (nadph).............

Yes, before photosynthesis evolved, oxygen was rare in Earth's atmosphere. Early Earth's atmosphere was composed mainly of carbon dioxide, nitrogen, and water vapor. As photosynthesis evolved and became more widespread, oxygen began to accumulate in the atmosphere, leading to the oxygen-rich environment we have today.

It is a part of the process of how a plant produces glucose and other sugars in order to live. In order to photosynthesize, a plant needs water from what is in the air (measured by humidity) or from what it takes from the ground in its roots, or on its leaves when it rains, and carbon dioxide from the atmosphere. The plant uses these two elements to produce by products oxygen, which is released as a waste product to the atmosphere, and glucose, which is uses for energy.

Specifically, water is needed for photosynthesis because it's electrons are used to replenish the lost electrons from the chlorophyll in photosystem II. The hydrogens from water are also used to make a proton gradient that powers the ATP synthase which is used to make ATP for the Calvin cycle. The oxygen is a waste product of the process.

The electrons transferred along the membrane from Photosystem II and Photosystem I use a series of protein complexes embedded in the thylakoid membrane called the electron transport chain. This chain consists of proteins that pass the electrons from one to another, ultimately leading to the production of ATP and NADPH which are essential for the light-dependent reactions of photosynthesis.

The products of photosynthesis are used as the reactants for cellular respiration, and vice versa.

Photosynthesis uses carbon dioxide (CO2) and water (H2O) to create organic molecules and oxygen (O2).

In turn, cellular respiration takes those two products (oxygen and organic molecules) to create carbon dioxide (CO2) and water (H2O)

Plants need photosynthesis to produce food by converting sunlight into energy. However, they also need respiration to break down this food and release the energy stored in it. Respiration provides the necessary energy for various metabolic processes essential for growth, maintenance, and reproduction in plants.

In Lab 4 of AP Biology, students typically investigate plant pigments and photosynthesis. This may involve using chromatography to separate pigments in plant leaves, measuring the rate of photosynthesis under different conditions, and exploring the relationship between light intensity and photosynthetic activity. The goal is to understand how plants capture light energy and convert it into chemical energy through photosynthesis.

The three main factors that affect the rate of photosynthesis are light intensity, carbon dioxide concentration, and temperature. These factors influence the amount of energy available for photosynthesis and the efficiency of the chemical reactions involved in converting carbon dioxide and water into glucose and oxygen.

Chlorophylls are essential pigments found in chloroplasts that capture light energy during photosynthesis. They absorb specific wavelengths of light and transfer that energy to other molecules to drive the production of ATP and NADPH, which are used in the Calvin cycle to convert carbon dioxide into glucose. Overall, chlorophylls play a crucial role in converting light energy into chemical energy within plants.

Photosynthesis is a process wherein it produces ATP(adenosine triphosphate) from ADP(adenosine diphosphate) and Pi (Inoraganic Phosphate) by using the energy from light to excite electrons that are passed along an electron transport chain. Coupled with the transfer of electrons is the pumping of hydrogen ions and the splitting of water molecules.

The process is into two phases:

Light dependent phase or photochemical reaction that occurs in the granum and requires the presence of light energy

it involves three major events:

a. Chlorophyll photoactivation is the capture of light energy by chlorophyll that results in the release of energized electrons

b. Photolysis is the splitting of water molecules into hydrogen ions, electrons and oxygen gas in the presence of light activated chlorophyll.

c. Photophosphorylation is the transfer of light energy absorbed by chlorophyll to molecules of ATP, the energy currency of the cell.

The following are produced during the light phase:

1. Oxygen gas..from water and released as a gaseous by-product of photosynthesis.

2. NADPH... a hyrogen ion from water and two electrons from chlorophyll

3. ATP...ADP and Pi combined in the presence of energy harnessed by chlorophyll from the sun.

Light independent phase involves the use of NADPH and ATP for the conversion of carbon dioxide into carbohydrates...please refer to the Calvin Cycle

Photosynthesis ends with the formation of a simple sugar, glucose. Four things may happen to this glucose:

A. It may be converted to sucrose and transported from the leaves to other parts of the plant.

B. It may be converted to starch and stored for future use of the plant.

C. It may be utilized to provide the raw materials from which other organic substances needed by the plant may be synthesized.

D. It may be utilized for cellular respiration.

Photosynthesis produces Glucose (C6H12O6) and Oxygen (O2).

Carbon dioxide and water are the two inorganic materials needed by the plant to carry out photosynthesis. Carbon dioxide is absorbed from the atmosphere through tiny pores on the leaves called stomata, while water is absorbed from the soil through the plant's roots.

6 cycles are required if you consider or start from 1 CO2 , but 2 cycles if you start from 3 CO2 .

Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight into chemical energy in the form of glucose. During photosynthesis, carbon dioxide and water are used in the presence of sunlight to produce glucose and oxygen. This process occurs in the chloroplasts of plant cells and is essential for the production of food and oxygen in the ecosystem.

No, reduction of oxygen does not occur during photosynthesis. In photosynthesis, oxygen is produced as a byproduct when water molecules are split during the light-dependent reactions in the thylakoid membranes of chloroplasts.

Photosynthesis primarily takes place in the thylakoid membrane and stroma of the chloroplast. The thylakoid membrane contains the photosystems responsible for light absorption and electron transport, while the stroma contains the enzymes for the Calvin cycle, where carbon fixation occurs.

The molecule used to replenish RuBP in the Calvin Cycle is phosphoglycerate (PGA). PGA is converted to RuBP through a series of enzymatic reactions, allowing the cycle to continue and fix more carbon dioxide.

The skin cells control our bodies skin tone, the Chloroplast controls the leafs color.

The equation for photosynthesis is below.

6CO2 + 6H2O + light energy >>> C6H12O6 + 6O2

So to answer your question, the main product in photosynthesis is a carbohydrate.

A full size Douglas fur tree will produce about 260 pounds of oxygen in a year. An oak tree will produce simmilar ammounts, as will most other large trees. Smaller bushes may produce around 20-40 pounds as will grass lawns.

Chlorophyll is the key compound that enables photosynthesis in green plants. It is a pigment that absorbs light energy and converts it into chemical energy, which is used to produce glucose and oxygen from carbon dioxide and water.

Visible light wavelengths, specifically in the range of 400-700 nanometers, play a crucial role in photosynthesis. These wavelengths are absorbed by chlorophyll and other pigments in plant cells to drive the process of converting light energy into chemical energy.

The amount of carbon dioxide the plants in the entire world take in is less than the amount of carbon dioxide organisms and human activities produce, so the concentration of carbon dioxide is increasing slowly. Another reason is that as more and more forests are being cleared, there are less trees to take in carbon dioxide for photosynthesis. The third reason is that at a certain concentration of carbon dioxide, the rate of photosynthesis stays constant.
