Key concepts: Structural Organisation in Animals (Class 11 Biology)
This chapter covers animal tissues and, using the cockroach and frog as examples, the structural organisation of animal body systems.
- Animal tissues
- Four basic types: epithelial (lining), connective (support, e.g. blood, bone), muscular and nervous tissue.
- Epithelial tissue
- Covers surfaces and lines cavities; classified by cell shape (squamous, cuboidal, columnar) and layering.
- Connective tissue
- Has cells in a matrix; includes loose/dense connective tissue, cartilage, bone and blood.
- Organ & organ system
- Tissues form organs; organs work together as systems (digestive, circulatory, etc.).
- Model organisms
- The cockroach (insect) and frog (amphibian) illustrate animal morphology and anatomy in detail.
💡 Exam tips for Structural Organisation in Animals
- Learn the four tissue types with one clear example of each (e.g. blood = connective tissue).
- Compare cockroach (open circulation, exoskeleton) and frog systems as exam case studies.
