Chapter Analysis
Intermediate12 pages • EnglishQuick Summary
Chapter 6, 'Tissues', introduces the concept of tissues in living organisms, highlighting the difference between plant and animal tissues. It explains that while plants are stationary and use dead supportive tissue, animals have living tissues due to their active lifestyle needs. The chapter elaborates on different plant tissues, specifically meristematic and permanent tissues, and outlines the diverse types of animal tissues including epithelial, connective, muscular, and nervous tissues. Functions and characteristics of each type are discussed, emphasizing their roles in growth and survival of plants and animals.

Additional Practice Questions
Explain the role of epithelial tissue in the human body.
mediumAnswer: Epithelial tissue forms a protective barrier in the body and covers all external surfaces of organs as well as internal cavities and glands. It controls permeability and allows selective absorption and secretion.
Compare the functions of xylem and phloem in plants.
easyAnswer: Xylem transports water and dissolved minerals from roots to other parts, while phloem distributes the sugars and nutrients produced by photosynthesis from leaves to growth sites and storage tissues.
What adaptations do plants have to minimize water loss?
mediumAnswer: Plants minimize water loss through adaptations such as waxy leaf surfaces, reduced leaf size, and the presence of stomata regulated by guard cells to control transpiration.
Why is connective tissue important in animals, and what are its main types?
mediumAnswer: Connective tissue supports, connects, and separates different types of tissues and organs in the body. Its main types include blood, bone, cartilage, tendons, and adipose tissue.
Describe the structure and function of muscle tissue in movement.
hardAnswer: Muscle tissue is composed of fibres capable of contraction. Skeletal muscles help in voluntary movements, smooth muscles control involuntary actions, and cardiac muscles consistently pump blood through rhythmic contractions.
