[B]. Carbon dioxide + Hydrogen + (Sunlight and Chlorophyll) → Carbohydrates + Oxygen
[C]. Nitrogen dioxide + Water + (Sunlight and Chlorophyll) → Carbohydrates + Ozone
[D]. Carbon dioxide + Water + (Sunlight and Chlorophyll) → Carbohydrates + Oxygen

[A]. Autotroph and Parasite
[B]. Heterotroph and Saprotroph
[C]. Heterotroph and Parasite
[D]. Autotroph and Saprotroph




Why do all living being need food?

All living organisms require food for cellular activities like growth, development and physical activities.

Who are Autotrophs?

Organisms which make their own food are called Autotrophs like plants.

What do you mean by Photosynthesis?

Photosynthesis is the process by which plants make their own food.

How do green plants prepare their food?

Green plants use water, carbon dioxide and sunlight to prepare their food by the process of photosynthesis.

Chlorophyll and Photosynthesis

When we see around us, we find that most of the plant leaves are green in colour. It is because leaf cells contain green pigments called Chlorophyll. The photosynthesis happens at this site of leaf’s cell. Chlorophyll helps in trapping of sun light energy. Water is absorbed by the root hairs from the soil and carbon dioxide coming from atmosphere is taken in through the stomata of leaf. Water and carbon dioxide combine in presence of sunlight trapped by chlorophyll and produces glucose and releases oxygen into the atmosphere. This complete process is called Photosynthesis.



Currently in Class test of standard 7 or school exams, MCQs are compulsory in each subject. These MCQs will help the students to understand the concepts given in Chapter 1 of Class 7 Science. Definitions, keywords and all extra questions are included in the form of multiple choice questions to provide a better practice for grade 7 student.
