Photosynthesis: Term photo synthesis was coined by Charles Reid Barnes in 1883. During photosynthesis the leaves containing chlorophyll in the presence of sunlight use carbon dioxide and water to synthesize glucose or sugar (simple carbohydrates). Carbohydrate which is produced in the process of photosynthesis is ultimately converted into starch and stored into leaves. From leaves it is transported to the parts of plants. Starch is a type of carbohydrate. The oxygen is so produced is released into atmosphere through the stomata. Leaves are known as the kitchen or food factories of the plants because photosynthesis takes place in leaves. Leaves look green because of the presence of cholrophyll. Besides leaves, photosynthesis takes place in other green parts of the plants also, such as in green stems. Sunlight is necessary for photosynthesis . Thus sun is the ultimate source of energy for all living organisms . The starch is carried to various parts of plants through pipe-like structures called phloem. The food stored in different parts of the plants are used by humans and animals. The chemical equation representing photosynthesis is as given below:
Water + Carbon dioxide —> Sugar + Oxygen
Sunlight, chlorophyll, water and carbon dioxide are essential for the process of photosynthesis. The food we eat is actually the solar energy captured by the leaves and stored in the form of food. This is why Sun is considered the ultimate source of energy.

DIRECTION : The questions in this segment consists of two statments, one labelled as "Assertion A " and the other labelled as "Reason R ". You are to examine these two statements carefully and decide if the Assertion A and Reason R are individually true and if so, whether the reason is a correct explanation of the assertion. select your answers to these items using codes given below. Assertion (a) : Water and minerals present in soil are absorbed by roots and transported to leaves. Reason (R) : Carbon dioxide from air is taken through stomata present on the surface of leaves. | |||

One of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
I have spent a wonderful time in Abhyas academy. It has made my reasoning more apt, English more stronger and Maths an interesting subject for me. It has given me a habbit of self studying
It has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice
Abhyas Methodology is very good. It is based on according to student and each child manages accordingly to its properly. Methodology has improved the abilities of students to shine them in future.

Abhyas is a complete education Institute. Here extreme care is taken by teacher with the help of regular exam. Extra classes also conducted by the institute, if the student is weak.
It was a good experience with Abhyas Academy. I even faced problems in starting but slowly and steadily overcomed. Especially reasoning classes helped me a lot.
It was good as the experience because as we had come here we had been improved in a such envirnment created here.Extra is taught which is beneficial for future.
About Abhyas metholodology the teachers are very nice and hardworking toward students.The Centre Head Mrs Anu Sethi is also a brilliant teacher.Abhyas has taught me how to overcome problems and has always taken my doubts and suppoeted me.
