What are the starting materials of photosynthesis?

The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf.

Is CO2 a starting material for photosynthesis?

Carbon is a raw material for photosynthesis, in the form of carbon dioxide. Green plants use it to make vital organic compounds. On the land, plants get the carbon they need as a gas from the air. In water, plants ranging from seaweeds to phytoplankton are supplied by dissolved carbon dioxide, CO2.

What is ET50 of photosynthesis?

The ET50 is the time it takes for 50% of the leaf disks to float and is a good indicator of the rate of photosynthesis. It was hypothesized that if the concentration of carbon dioxide was increased, then the rate at which photosynthesis occurs will also increase.

What is the starting form of energy in photosynthesis?

light
In photosynthesis, the starting energy is in the form of light and in cellular respiration the starting energy is stored in the chemical bonds of glucose.

What are the starting materials and products?

The starting materials of a chemical reaction are called the reactants and the materials that are made are called the products.

What are the reactants starting materials?

Starting material: A reactant in a chemical reaction or mechanism step. This term is usually reserved for the reactant that contributes the greatest number of carbon atoms to the product, or the reactant that is considered most ‘precious’ because of availability, cost, effort to synthesize, etc.

What starts and ends with photosynthesis?

In photosynthesis, solar energy is harvested and converted to chemical energy in the form of glucose using water and carbon dioxide. Oxygen is released as a byproduct.

What are the starting materials of photosynthesis and cellular respiration?

Photosynthesis makes glucose and oxygen, which are then used as the starting products for cellular respiration. Cellular respiration makes carbon dioxide and water (and ATP), which are the starting products (together with sunlight) for photosynthesis.

Why is sodium bicarbonate used in photosynthesis experiment?

The function of the sodium bicarbonate in this experiment, was providing carbon dioxide for photosynthesis to occur. Light independent reactions take part in the stroma. For photosynthesis to happen for a light independent reaction, carbon dioxide needs to enter the plant.

How do you find ET50?

To determine the ET50-light for this trial, plot the percent leaf disk floating as a function of time: From the above graph, we can interpolate that 50% of the leaf disks floated at 5.5 minutes. Therefore, the ET50-light is 5.5 minutes.

What is the original source of energy that causes electrons to flow during photosynthesis?

A photon of light energy travels until it reaches a molecule of chlorophyll. The photon causes an electron in the chlorophyll to become “excited.” The energy given to the electron allows it to break free from an atom of the chlorophyll molecule.

In which form is energy stored at the end of photosynthesis?

Sunlight is converted to chemical energy in the form of ATP (adenosine triphosphate), which is the main energy-storing molecule in living organisms. ATP is then transported throughout the chloroplast and used to provide the chemical energy necessary to power other metabolic reactions.
