#6 Unseen Passages for Class 11
The human immune system is a complex and sophisticated system that helps protect the body against illness and disease. It consists of a network of cells, tissues and organs that work together to detect and eliminate harmful substances such as viruses, bacteria and toxins. The immune system also plays an important role in protecting against cancer and other diseases.
The immune system is made up of two main branches: the innate immune system and the adaptive immune system. The innate immune system is the first line of defence and consists of physical barriers, such as the skin and mucous membranes, as well as non-specific immune cells that attack any foreign substances they encounter. On the other hand, the adaptive immune system is more specific and involves the production of antibodies that target specific pathogens.
The immune system works constantly, but it can be weakened by various factors, such as stress, poor diet and lack of sleep. To maintain a strong immune system, it is important to practice good hygiene, eat a healthy diet, exercise regularly and get enough sleep.
Questions:
What is the function of the human immune system?
Answer: The function of the human immune system is to protect the body from illness and disease by detecting and eliminating harmful substances such as viruses, bacteria and toxins.
What are the two main branches of the immune system?
Answer: The two main branches of the immune system are the innate immune system and the adaptive immune system.

The photosynthesis process is the primary way that plants convert energy from the sun into usable chemical energy. It is a complex process that involves the conversion of light energy into chemical energy through a series of reactions occurring in the chloroplasts of plant cells.
Photosynthesis is essential for plants to survive, as it allows them to produce the energy they need to grow and thrive. It plays an important role in the global carbon cycle, as plants absorb carbon dioxide from the atmosphere and convert it into glucose through photosynthesis. It helps in reducing the level of carbon dioxide in the atmosphere and reducing the effects of climate change.
Photosynthesis occurs in two stages: light-dependent reactions and light-independent reactions. Light-dependent reactions use energy from the sun to make ATP and NADPH, which are used in light-independent reactions to make glucose.
