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: Please briefly sum up what this article says about orcas' bodies. 

Orcas are known for their long dorsal fin (the fin on the animal's back) and black-and-white coloring. The black-and-white coloring helps to camouflage them by obscuring their outline in the water. Just behind the dorsal fin is a patch of gray called a "saddle" — because it looks like a riding saddle. 

An orca's body is cylindrical and tapers at each end to form a hydrodynamic shape. This shape, along with the orca's large size and strength, makes it among the fastest marine mammals, able to reach speeds in excess of 30 knots (about 34 mph, or 56 km/h). Orcas have massive teeth, which can grow up to 4 inches (10 centimeters) long, according to National Geographic.
Response: Orcas have teeth up to 4 inches long, long dorsal fins, black-and-white camouflage coloring, and gray saddles on their cylindrical, hydrodynamic-shaped bodies. They are among the fastest marine mammals, reaching over 30 knots (34 mph or 56 km/h).

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.

Briefly explain the concept of photosynthesis in plants.

Photosynthesis is the process by which green plants use sunlight to synthesize food. Chlorophyll in the leaves captures light energy, which converts carbon dioxide and water into glucose and oxygen.
