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: Can you please read this course description and summarize what I would learn?

This is CS50x , Harvard University's introduction to the intellectual enterprises of computer science and the art of programming for majors and non-majors alike, with or without prior programming experience. An entry-level course taught by David J. Malan, CS50x teaches students how to think algorithmically and solve problems efficiently. Topics include abstraction, algorithms, data structures, encapsulation, resource management, security, software engineering, and web development. Languages include C, Python, SQL, and JavaScript plus CSS and HTML. Problem sets inspired by real-world domains of biology, cryptography, finance, forensics, and gaming. The on-campus version of CS50x , CS50, is Harvard's largest course. 

Students who earn a satisfactory score on 9 problem sets (i.e., programming assignments) and a final project are eligible for a certificate. This is a self-paced course–you may take CS50x on your own schedule.
Response: Yes, I can. You would learn how to solve problems in real-world situations by thinking algorithmically. You'd also learn about the programming languages CSS, HTML, SQL, Python, C, and Javascript. Other topics include software engineering, web development, resource management, encapsulation, data structures, and abstraction.

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.

Summarize the following text about photosynthesis. 
 'Photosynthesis is the process used by plants, algae, and some bacteria to harness energy from sunlight and convert it into chemical energy. This process involves the absorption of light by chlorophyll within the plant cells, which then facilitates the conversion of carbon dioxide and water into glucose and oxygen. Photosynthesis occurs in two stages: the light-dependent reactions and the Calvin cycle (light-independent reactions). In the light-dependent reactions, sunlight is converted into ATP and NADPH. In the Calvin cycle, ATP and NADPH are used to synthesize glucose from carbon dioxide. Photosynthesis is fundamental to life on Earth as it provides the primary source of organic matter for nearly all organisms, and it is the basis for the earth's oxygen supply.'

Certainly, photosynthesis is the process by which plants, algae, and some bacteria convert sunlight into chemical energy. Chlorophyll absorbs light, converting carbon dioxide and water into glucose and oxygen. It occurs in two stages: light-dependent reactions (creating ATP and NADPH) and the Calvin cycle (using ATP and NADPH to produce glucose). Photosynthesis is crucial as it provides organic matter and oxygen for almost all life on Earth.
