Resource: Anything which has some utility for us is called a resource. Some resources have economic value, while some do not. For example; milk has economic value, but a beautiful landscape has no economic value. But both are important because both satisfy some human needs.
Resources are usually classified into three types, viz. natural, human made and human resources.
Natural Resource: Resources which are obtained from nature are called natural resources. Some of the natural resources can be used directly, while for using some others we need the help of some technologies.
Human Made Resources
When a natural resource undergoes drastic change by human intervention, it becomes human-made resource. For example; iron ore is processed to make steel and hence steel is a man-made resource. Buildings, bridges, railways, machines, etc. are examples of human-made resources. Technology is also a human-made resource.
Human Resources
People are the human resources. Education and health improve the quality of human resources. Improving the quality of people’s skills to enable them to create more resources is called human resource development.

Microbes are also used to prepare antibiotics, which are used to treat several bacterial infections. Antibiotics are chemical substances that kill disease-causing microbes. It is quite interesting to find that there are some microbes which cause diseases; on the other hand, some other microbes help in preparation of antibiotics, and thus, cure diseases.

Chlorophyll is vital for photosynthesis, which allows plants to absorb energy from light. Chlorophyll molecules are arranged in and around photosystems that are embedded in the thylakoid membranes of chloroplasts. The chlorophyll molecule consists of a central magnesium atom surrounded by a nitrogen-containing structure called a porphyrin ring; attached to the ring is a long carbon–hydrogen side chain, known as a phytol chain. Chlorophyll is vital for photosynthesis, which allows plants to absorb energy from light. Chlorophyll molecules are arranged in and around photosystems that are embedded in the thylakoid membranes of chloroplasts.

Robert Hook discovered cells in 1665. When he observed thin slices of cork (part of bark of a tree) under a self-designed microscope, he noticed that there are many partitioned boxes or compartments like a honeycomb. Each box was separated from the other by a wall. Hook coined the term “cell” for each box.
