Question

Photosynthesis in plants is a $ \ldots \ldots \ldots $change.
${\text{A}}{\text{. }}$chemical
${\text{B}}{\text{. }}$physical
${\text{C}}{\text{. }}$both A and B
${\text{D}}{\text{. }}$none of the above

Answer 1

Hint: -To answer this question first we have to have knowledge about photosynthesis so grab information about photosynthesis and then we have to understand what is changing and what is chemical and physical change.

Complete answer:
Photosynthesis: -
We all have heard the word photosynthesis in our science chapter as plants make their own food through the process of photosynthesis. Photosynthesis is the name of the process in which plants use air, water, sunlight and many more ingredients from the soil to make their own food in the leaves.
It is the process in which light energy changes into chemical energy.
Photosynthesis is a chemical change as light energy is converted into chemical energy by plants.
Now we should also understand what is change and what is physical change and chemical change?
Change: -
Change is the law of nature. Without change nature can’t exist so for the existence of nature change is required in every aspect of life.
Physical change:
Physical change is the change in which physical substance changes, not its chemical composition changes.
Chemical change:
A chemical change is a change of material in which whole chemical composition changes that means a new substance is formed with new properties.
Now from above understanding we can say that
Option A is the correct option.

Note: -Whenever we get this type of question the key concept of solving is we have to have basic knowledge of all the terms used in the question and option. Physical change means change in physical properties and chemical change means change in chemical properties.
