Is plants using co2 and h2o to form o2 and sugar a physical change?
Plants using carbon dioxide and water to form oxygen & sugar is a chemical or physical change? physical. it grows and the leaves change color.
Is plants make sugar from carbon dioxide and water a physical or chemical change?
Photosynthesis is the process through which plants convert light energy into chemical energy. Here is the chemical reaction involved: As we can see, water and carbon dioxide combine to form glucose and oxygen. Since new chemical species are formed, photosynthesis is clearly a chemical change.
Is combustion of sugar to produce carbon dioxide and water a physical change?
mix the sugar with something else or, melt it, it’s still sugar. But in the fourth example, when sugar reacts inside the body, it ceases to be sugar and is changed into other substances. In this case, carbon dioxide and water are formed. In a physical change, we still have the same substance before and after.
How do plants make oxygen during photosynthesis?
By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2).
What happens to water and carbon dioxide in a plant cell?
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.
How do plants and animals take in gases?
By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2). Just like you, plants need to take in gases in order to live. Animals take in gases through a process called respiration.
What is the chemical formula for photosynthesis?
If we were to write a formula for photosynthesis, it would look like this: 6CO2 + 6H2O + Light energy → C6H12O6 (sugar) + 6O2 The whole process of photosynthesis is a transfer of energy from the Sun to a plant. In each sugar molecule created, there is a little bit of the energy from the Sun, which the plant can either use or store for later.
