How would the environment change if there were fewer plants to carry out photosynthesis?
How would the environment change if less plants were able to photosynthesise? Sunlight is absorbed into the chlorophyll of a plant. The energy can be used to make organic compounds such as glucose from carbon dioxide. The organic molecules in plants are then consumed by animals, both directly and indirectly, as energy.
How does photosynthesis affect plants?
Photosynthesis is a process that plants use to produce food. plants capture light energy during photosynthesis. Plants harness the energy of the sunlight to transform water and carbon dioxide into glucose. Starch is stored as food in seeds and other plant parts.
How does water level affect photosynthesis? The rate of photosynthesis will be affected by how much water is available to the plant. The plant will not produce enough water. The stomata of the plant will close and it will become devoid of COA. It is also possible to alter the amount of carbon dioxide the plant receives.
It is also important to understand which pair of compounds are products of photosynthesis.
photosynthesis. water, and glucose. Carbon dioxide and glucose.
Why does each plant have a different rate of photosynthesis?
Changes in the leaf's condition (aging, tearing) The arrangement of leaves on a branch and even the shape and size affect the amount of photosynthesis. There are two types of plants that have evolved over time, according to their tolerance for light.

What is photosynthesis step by step?
The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
How does photosynthesis start?
Photosynthesis begins when light strikes Photosystem I pigments and excites their electrons. The energy passes rapidly from molecule to molecule until it reaches a special chlorophyll molecule called P700, so named because it absorbs light in the red region of the spectrum at wavelengths of 700 nanometers.
Why is photosynthesis so important?
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy.
What are the two main functions of chloroplasts?
The two main functions of chloroplasts are to produce food (glucose) during photosynthesis, and to store food energy.
How is photosynthesis beneficial to humans?
First, it makes it possible for plants to survive. Because of photosynthesis, plants essentially function as filters that take carbon dioxide, which is poisonous to humans and many other life forms, from the atmosphere and replace it with oxygen, which makes life possible.
What is photosynthesis short answer?
Photosynthesis is the process by which plants and other things make food. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars that the cell can use as energy. As well as plants, many kinds of algae, protists and bacteria use it to get food.
What parts of a plant are involved in photosynthesis?
Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to make photosynthesis happen.
What pair of molecules are broken down by the cell?
Glucose and other food molecules are broken down by controlled stepwise oxidation to provide chemical energy in the form of ATP and NADH.
Which two compounds are raw materials used in cellular respiration?
Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
Which compound is both the product of photosynthesis and a starting material for respiration?
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
In which organism does cellular respiration not take place in the mitochondria?
Electron Transport Chain
It is the only part of cellular respiration that directly consumes oxygen; however, in some prokaryotes, this is an anaerobic pathway. In eukaryotes, this pathway takes place in the inner mitochondrial membrane. In prokaryotes it occurs in the plasma membrane.How energy changed in form from its original source to the ATP molecule?
To summarize, the energy in the ATP molecule comes from energy that is released by catabolic reactions like cellular respiration which occurs in the mitochondria. The energy was originally in the glucose molecule. This energy can be used to join ADP plus inorganic phosphate to form the high energy ATP molecule.
Why is water important to photosynthesis?
During the process of photosynthesis, six molecules of carbon dioxide and six molecules of water react in the presence of sunlight to form one glucose molecule and six molecules of oxygen. The role of water is to release oxygen (O) from the water molecule into the atmosphere in the form of oxygen gas (O2).
How is water formed in photosynthesis?
The photosynthetic process produces several products. Water is also a product of photosynthesis. This water is produced from the oxygen atoms in the carbon dioxide molecules. The oxygen molecules released into the atmosphere come exclusively from the original water molecules, not from the carbon dioxide molecules.
How is light used in photosynthesis?
The process of photosynthesis occurs when green plants use the energy of light to convert carbon dioxide (CO2) and water (H2O) into carbohydrates. Light energy is absorbed by chlorophyll, a photosynthetic pigment of the plant, while air containing carbon dioxide and oxygen enters the plant through the leaf stomata.
What are the 4 factors that affect photosynthesis?
The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
Why is water split in photosynthesis?
Water is absolute requirement for photosynthesis to occur. During Light reactions of Photosynthesis, the chlorophyll will be activated by light. This light activated chlorophyll will split the water molecule. Water molecule is split to release H+ ions and also oxygen.
