NCERT Solutions Class 11 Biology Chapter 7 - Structural Organisation in Animals
NCERT Solutions for Class 11 Biology Chapter 7 (Structural Organisation in Animals) explain the different types of animal tissues and how they form organs and organ systems. The chapter covers four main types of animal tissues: epithelial, connective, muscular, and neural tissues. It also explains the external features and internal structure of a frog and the functions of its different body parts.
NCERT Solutions for Class 11 Biology Chapter 7 by ALLEN explain animal tissues, where they are found, and what they do. Students can learn about the frog's digestive, circulatory, respiratory, excretory, nervous, and reproductive systems. These solutions help students understand the chapter, answer NCERT textbook questions, revise important topics, and prepare for school exams and NEET.
1.0NCERT Solutions for Class 11 Biology Chapter 7 Structural Organisation in Animals: Key Concepts
Class 11 Biology Chapter 7 explains how animal bodies are organised, from cells and tissues to organs and organ systems. The chapter covers the main types of animal tissues and the morphology and anatomy of frogs.
- Animal Tissues: Learn about the four main types of animal tissues: epithelial, connective, muscular, and neural tissues.
- Epithelial Tissue: Understand simple epithelium, including squamous, cuboidal, and columnar types, as well as compound epithelium.
- Connective Tissue: Study loose connective tissues, such as areolar and adipose tissue; dense connective tissues, such as tendons and ligaments; and specialised connective tissues, including cartilage, bone, and blood.
- Muscle Tissue: Learn the differences between skeletal (striated), smooth (non-striated), and cardiac muscles based on their structure, location, and functions.
- Neural Tissue: Understand the structure and functions of neurons and neuroglial cells in the nervous system.
- Organ and Organ System: Learn how different tissues work together to form organs and how organs combine to perform functions within organ systems.
- Frog Morphology and Anatomy: Study the external features and internal structure of frogs, including their digestive, circulatory, respiratory, excretory, nervous, and reproductive systems.
2.0Detailed NCERT Textbook Solutions : Class 11 Biology Chapter 7
- Draw a neat diagram of digestive system of frog. Ans.
- Mention the function of the Ureters in frog Ans. Ureters in frog: Ureter is a transparent duct which arise from outer portion of kidney. In the "male frogs, ureter acts as urinogenital duct which runs backwards from kidneys and opens into the cloaca. It carries both urine and spermatozoa from kidney to the cloaca. In female, ureter conducts only urine from kidneys to the cloaca.
