FAQs on Mindmap: Tissues - Science Class 9

1. What are the different types of tissues in the human body?
Ans. There are four main types of tissues in the human body: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Each type of tissue has specific functions and characteristics.
2. How does epithelial tissue protect the body?
Ans. Epithelial tissue acts as a protective barrier for the body. It covers the surfaces of organs, lines body cavities, and forms glands. It protects underlying tissues from physical damage, dehydration, and invasion by pathogens.
3. What is the role of connective tissue in the body?
Ans. Connective tissue provides support and connects different structures in the body. It helps in the formation of organs, tendons, ligaments, and bones. Connective tissue also plays a crucial role in transporting nutrients, waste products, and immune cells throughout the body.
4. How does muscle tissue enable movement?
Ans. Muscle tissue is responsible for movement in the body. There are three types of muscle tissue: skeletal, cardiac, and smooth. Skeletal muscles enable voluntary movements, cardiac muscles control the contraction of the heart, and smooth muscles facilitate involuntary movements in organs.
5. What is the function of nervous tissue?
Ans. Nervous tissue allows the body to receive and transmit electrical impulses, enabling communication and coordination between different parts of the body. It forms the brain, spinal cord, and nerves, which are essential for sensory perception, motor control, and overall body functioning.
