Answer: The evidence that supports the conservation law is that
Carbon dioxide becomes glucose and oxygen during photosynthesis
. The law of conservation of mass states that in a chemical reaction, mass is neither created nor destroyed.
What evidence supports the conservation law?
The proof that supports the law of conservation of energy is that
when photosynthesis takes place, carbon(iv)oxide is broken down into two forms: oxygen and glucose
. This reaction proves the law of energy conservation, which approves that mass cannot be formed or dismantled in a reaction involving chemicals.
How does conservation of mass relate to photosynthesis?
The law of conservation of matter is connected to photosynthesis because
matter like carbon dioxide and water go into the plant
and, with the help of energy, the plant creates a new form of matter — sugar, or glucose, and releases the oxygen into the atmosphere that is formed from the carbon dioxide.
Does energy from sunlight becomes glucose during photosynthesis?
During photosynthesis, plants trap light energy with their leaves. Plants
use the energy of the sun to change water and carbon dioxide into a sugar
called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls.
What is the name of the process that turns carbon dioxide into glucose?
During
photosynthesis
, plants take in carbon dioxide (CO
2
) and water (H
2
O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Is it true during photosynthesis water and carbon dioxide become glucose and oxygen?
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and
carbon dioxide to glucose
. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
How does the carbon cycle support the law of conservation of mass?
The Law of Conservation of Matter states
that matter cannot be created or destroyed
. The carbon cycle is an example of the Law because the same carbon atoms are being recycled through the carbon cycle. … Carbon is used for energy, and some is stored for growth.
Why is it hard to prove the law of conservation of mass when a gas is produced?

How do plants capture CO2?
Plants extract the carbon dioxide from the air and use
it in photosynthesis process to feed themselves
. The carbon dioxide enters the leaves of the plant through small pores called stomata. … The plant uses sunlight as energy to perform this chemical reaction.
How do plants break down CO2?
Plants
use photosynthesis
to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.
What organisms can capture CO2 from the atmosphere and incorporate?
What organisms can capture co2 from the atmosphere and incorporate those carbon molecules into their own?
Chemoautotrophs
. Chemoautotrophs are able to synthesize their own organic molecules from the fixation of carbon dioxide. These organisms are able to produce their own source of food, or energy.
How do plants get the carbon dioxide they need for photosynthesis?
Plants and algae can only carry out photosynthesis in the light. Plants get carbon dioxide
from the air through their leaves
, and water from the ground through their roots. Light energy comes from the Sun. The oxygen produced is released into the air from the leaves.
What is the role of CO2 in the Calvin cycle?
In the Calvin cycle, carbon atoms from CO2start text, C, O, end text, start subscript, 2, end subscript are fixed (incorporated into organic molecules) and
used to build three-carbon sugars
. This process is fueled by, and dependent on, ATP and NADPH from the light reactions.
What is photosynthesis class 6th?
Hint: Photosynthesis is the process by which green plants prepare their own food with the help of carbon-dioxide, water, chlorophyll and light. By this process the light energy is converted into
chemical energy
.
How do plants obtain the water and carbon dioxide they use for this process?
For
photosynthesis
green plants take carbon dioxide from the air. The carbon dioxide enters the leaves of the plant through the stomata present on their surface. … A large amount of water is also lost from the cells of the plant leaves through open stomatal pores.
What is the relationship between water light and co2 and photosynthesis quizlet?
Water and carbon dioxide are reactants for photosynthesis. Chlorophyll captures sun's light energy and then plants chemically combine this with water and carbon dioxide
to make glucose (sugar) and oxygen
.
What is the law of conservation of mass simplified?
The law of conservation of mass is a fundamental principle of physics. According to this law,
matter can be neither created nor destroyed
. In other words, the mass of an object or collection of objects never changes, no matter how the parts are rearranged.
What is the relationship between water light and co2 and photosynthesis?
Light provides the energy for photosynthetic pigments to convert carbon dioxide (CO
2
) and water
into sugars and oxygen
. As light intensity increases Ð until a point Ð the amount of sugars increases and thus, more energy is available for plant growth and maintenance.
What are some real life examples of the law of conservation of mass?
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns,
the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted
. So the mass of the product equals the mass of the reactant.
How does the law of conservation of mass demonstrated in the simulation you performed?
Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that
mass is conserved in chemical reactions
.
Where do you think the law of conservation of mass is used in the real world and why is it useful?
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants. The law of conservation of mass is
useful for a number of calculations
and can be used to solve for unknown masses, such the amount of gas consumed or produced during a reaction.
How does Antoine Lavoisier describe the law of conservation of mass?
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery
that mass is neither created nor destroyed in chemical reactions
. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.
Does the law of conservation of mass always hold true?
The fundamental conservation law of the universe is the conservation of mass-energy. … Mass is therefore never conserved because a little of it turns into energy (or a little energy turns into mass) in every reaction. But
mass+energy is always conserved
. Energy cannot be created out of nothing.
What is the importance of photosynthesis Class 6?
–
It provides food for all living beings
but the process occurs in the leaves of green plants. – It fixes and balances the amount of carbon dioxide and oxygen in the atmosphere by plants exhaling oxygen and animals and humans exhaling carbon dioxide.
What can you do in return for the help of photosynthetic organisms in performing photosynthesis?
