Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: What does this text say in one sentence?

Onceropyga pulchra is a species of moth in the family Zygaenidae. It is found in Australia in south-eastern Queensland and eastern New South Wales.[1]

The length of the forewings is 6.5 mm for males and 8 mm for females. The upperside of the forewings is dark brown with a slightly lighter spot at the end of the cell, distally bordered by a suffusion of blackish scales. The underside is dark grey brown, but slightly lighter medially. The hindwings are blackish on both sides, but slightly lighter basally, with a light brown costal margin.[1]
Response: Onceropyga pulchra, a species of moth found in south-eastern and eastern Australia, has wings between 6.5-8mm in length, is dark and lighter brown with blackish scales on the upperside and dark grey-brown and blackish coloring on the underside.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Give a brief overview of this text:

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can be later released to fuel the organisms' activities. This process primarily occurs in the chloroplasts of plant cells, where light energy is used to convert carbon dioxide and water into glucose and oxygen.
