When grass grows, it is a chemical change that results in physical changes such as a change in shape. When the grass is cut down, the chemical changes are reversed and the physical change is reversed. A grass, on the other hand, is an organism that has been introduced to a new area and has adapted to its new environment.
For example, if you have a lawn in your front yard, you probably have weeds growing in it. If you remove the weeds, they will die and you will be left with a beautiful lawn. The same thing is true for grasses and weeds.

Is a plant growing a chemical change?
Growth of plant is a chemical change because it involves photosynthesis reaction, and many of the photosynthetic reactions occur in the chloroplasts of plants, which are the organelles that make up the plant’s cell walls. Chlorophyll is the pigment in plants that gives them their green color. It is made up of two different types of pigments, chloroplast and chlorosulfur.
Is green grass a chemical change?
Is it a chemical or physical change in the grass?. The grass takes in carbon dioxide and water, and uses light energy to create oxygen and hydrogen. Physical – plants use sunlight to photosynthesize and use the energy to grow and reproduce.
This is the same process that occurs in nature, but it is not as efficient as it could be due to the fact that plants have a limited amount of energy available to them.
In order for plants to use this energy efficiently, they need to be able to store it for later use, which is why plants need a lot of water and nutrients in order to survive and grow. Plants also need the right conditions for their growth and reproduction to occur.
For example, if the temperature is too cold, the plants will not grow as well as they would if they were in a warmer environment. These are just a few examples of the many factors that can affect the growth of a plant.
Is cutting of grasses a chemical change?
Cutting the grass is one of the irreversible physical changes. Since pieces cannot be put back together to form a tree, firewood is an irreversible physical change. The composition of the wood doesn’t change when it is cut. The composition of a piece of firewood is the same as when it was cut from a tree, except that it has been heated to a higher temperature.
When the piece is heated, it becomes a different composition than it would have been if it had never been cut, so it is no longer a wood that can be used to make a fire. The best way to determine whether you are cutting a good wood for a fireplace is to look at the size of the firebox.
If it’s too small, you won’t be able to get enough air into the fireplace to keep it from burning out, and you’ll end up with a hot, smoldering mess.
Why growth of plant is a physical change?
Physical growth of the plant is considered as well as chemical change. Growth of the plant occurs due to increase in the cell number and cell size. The plant’s size and mass have an effect on its growth. It is a very slow process and depends on many factors.
It is also a chemical process because it is caused by the action of enzymes and other chemical reactions. The growth process of a plant can be divided into three phases: vegetative, reproductive, and metamorphic. Vegetative phase is the stage of growth in which the seedlings are growing. Reproductive phase occurs when the seeds germinate and develop into new plants.
Mature plants are mature when they reach a height of at least 1.5 m and have a diameter of between 1 and 2 m. Metamorphosis is a process that takes place after the plants have reached maturity. During this phase, the leaves change color from green to yellow to red and finally to brown.
Why growing of trees is chemical change?
This is because growth of a tree involves changes in overall shape and size of the tree (tree on growing becomes bigger in size and its branches spread out). So, if you want to grow a bigger tree, you need to increase the amount of carbon in your soil.
This is done by adding more organic matter to the soil and increasing the rate at which it decomposes into carbon dioxide (CO2) and water vapour (H2O). This process is called carbon fixation and is the main reason why trees grow bigger than they used to.
