The reactants of photosynthesis include?
glucose, solar energy, carbon dioxide, water, oxygen & chlorophyll
Why is sunlight necessary in photosynthesis?
you do not necessarily need sunlight but without light there is no photosynthesise because a plant needs it to preform photosynthesis.
Yes you do! The human body required sunshine in order to synthesize Vitamin D. Without adequate sunshine or compensating nutrition you will suffer from rickets, a deforming disease.
Where does cellular respiration occur and in what organelle?
Cellular respiration starts in the cytoplasm of the cell, and then enters the mitochondria.
During light dependent reactions plants use the energy in ATP and nadph to build what?
During light-dependent reactions, plants use the energy in ATP and NADPH to build glucose molecules through a process known as the Calvin cycle. This cycle involves carbon fixation, reduction, and regeneration of the molecule RuBP to produce glucose, which serves as a source of energy for the plant.
What are the two molecular groups of photosynthesis?
The two molecular groups involved in photosynthesis are chlorophyll and carotenoids. Chlorophyll is responsible for capturing light energy and initiating the light-dependent reactions, while carotenoids help protect the plant from damage by dissipating excess light energy.
What chemical elements are involved in photosynthesis?
water, light energy, and carbon dioxide make water and glucose (sugar) :)
How is starch linked to photosynthesis?
Green plants are producers. This means that they can survive without animals! They can make lots of organic chemicals from a few simple inorganic chemicals. They need simple things like carbon dioxide and water and can make complex things like sugar, starch, fat, and proteins.
What type of rate of reaction is photosynthesis?
Photosynthesis is a chemical reaction that is both endothermic (requires energy input from sunlight) and involves multiple reaction steps. It is a complex process where light energy is converted into chemical energy by plants, algae, and some bacteria.
How does stomata release water from a leaf?
Stomata release water through a process called transpiration. Water vapor exits the leaf through the open stomata, driven by a combination of factors such as temperature, humidity, and air movement. This process helps regulate the water balance in the plant and contributes to the transportation of nutrients throughout the plant.
Do extra sugar molecules pass out of the plant through the stomata?
No, extra sugar molecules are transported out of the plant through specialized cells called phloem. Stomata are responsible for gas exchange, allowing carbon dioxide to enter and oxygen to exit the plant.
Does photosynthesis take carbon dioxide out of the atmosphere?
No, Cellular Respiration returns carbon dioxide back into the atmosphere:
Photosynthesis: Carbon Dioxide + Water -> Light Energy -> Sugar + Oxygen
Cellular Respiration: Sugar + Oxygen -> C.R. -> Carbon Dioxide + Water
Why photosynthesis is called oxidation reduction process?
Photosynthesis is called an oxidation-reduction process because it involves the reduction of carbon dioxide to glucose (an energy-rich molecule) coupled with the oxidation of water to produce oxygen. During this process, electrons are transferred from water to carbon dioxide, resulting in a redox reaction that is essential for creating energy for the plant.
How can cell shape be modified so that diffusion can support life processes?
Well, the scientific theory of physhiology states that not only can a cell be submerged in isotonic fluild for diffusion to prosper, but that it can also be sliced into horizontal strips for a cell's asymmetrates to line up and increase the practical surfaxe area that makes the shape slightly oblique.
What is chlorophyll and what is it's role in photosynthesis?
Chlorophyll is a green pigment found in the chloroplasts of plant cells that is essential for photosynthesis. It absorbs light energy and helps convert it into chemical energy in the form of sugar, which the plant uses as food. Chlorophyll plays a crucial role in capturing sunlight and converting it into usable energy for the plant.
Who is involved in photosynthesis?
Photosynthesis involves plants, algae, and some bacteria. They have chlorophyll, a pigment that captures sunlight energy, allowing them to convert carbon dioxide and water into glucose and oxygen. This process is essential for the production of food and oxygen in the ecosystem.
How does solar power compare to light dependent reactions?
Solar power harnesses sunlight to generate electricity, while light-dependent reactions occur in photosynthesis to produce ATP and NADPH using light energy. Solar power is a technology humans have developed to mimic the energy-conversion process found in nature.
What group is organism that carries out photosynthesis in a manner similar to plants?
Algae are organisms that carry out photosynthesis in a manner similar to plants. They are eukaryotic organisms that can be found in various aquatic environments, ranging from freshwater to marine habitats. Like plants, algae use chlorophyll to capture sunlight and convert it into energy through photosynthesis.
What is broken down into CO2 and H2O during cellular respiration?
Glucose is broken down into carbon dioxide (CO2) and water (H2O) during cellular respiration to release energy. This process occurs in the mitochondria of cells to produce ATP, the cell's main energy source.
The movement of protons during ATP production is called what?
The movement of protons during ATP production is called chemiosmosis. In this process, protons are pumped across a membrane, creating an electrochemical gradient that drives ATP synthesis.
What veins make photosynthesis?
In plants, photosynthesis primarily occurs in the mesophyll cells of the leaves. These cells are rich in chloroplasts, which contain the pigment chlorophyll necessary for capturing sunlight and converting it into chemical energy. Veins in the leaves help transport water and nutrients to the mesophyll cells for photosynthesis to take place efficiently.
What is the structure that allow photosynthesis to occur?
The structure that photosynthesis takes place in is called a chloroplast in plants. However, not all photosynthesis takes place in the chloroplast. Photosynthetic bacteria for example have no chloroplast, and yet they photosynthesize. Another possible answer to this could be chlorophyll, but again there are differences; different groups of organisms use different types of chlorophyll to facilitate photosynthesis. Thus, I think that the only true answer to this question is that the Sun is THE structure that allows photosynthesis to occur. However, in modern times even this is technically incorrect, as photosynthesis can be stimulated by any suitable light source giving off light at the proper wavelength, for example; a lightbulb. So perhaps the only correct answer is that light itself is what allows photosynthesis to occur.
What process requires sunlight?
This question refers how plants produce glucose through the chemical pathway of photosynthesis. That being said photosynthesis produces organic molecules from the organic molecule of carbon dioxide (CO2).
What part of the plant completes photosynthesis?
The leaves of a plant are the primary organs that complete photosynthesis. Within the leaves, specialized structures called chloroplasts house the chlorophyll pigment responsible for capturing light energy and converting it into chemical energy through the photosynthetic process.
The food produced by plants during photosynthesis is used?
The food produced by plants during photosynthesis is used as a source of energy for the plant's growth and metabolism. This stored energy can also be used by other organisms that consume plants for their own survival. Additionally, some of the food produced may be stored in the form of starch for later use by the plant.
