NCERT Solutions for Class 11 Biology Chapter 7 - Structural Organisation in Animals

 

NCERT Solutions for Class 11 Biology Chapter 7 - Structural Organisation in Animals: You may be surprised to know that all complex animals consist of only four basic types of tissues. These tissues are organized in specific proportions and patterns to form an organ like stomach, lung, heart, and kidney. When two or more organs perform a common function by their physical and/or chemical interaction, they together form the organ system, e.g., digestive system, respiratory system, etc. Cells, tissues, organs and organ systems split up the work in a way that exhibits division of labor and contributes to the survival of the body as a whole.

In multicellular animals, a group of similar cells along with intercellular substances perform a specific function. Such an organization is called tissue.

Here, the important topics of NCERT Class 11 Biology Chapter 7 - Structural Organisation in Animals are mentioned below:

7.1 Animal Tissues

7.1.1 Epithelial Tissue

7.1.2 Connective Tissue

7.1.3 Muscle Tissue

7.1.4 Neural Tissue

7.2 Organ and Organ System

7.3 Earthworm

7.3.1 Morphology

7.3.2 Anatomy

7.4 Cockroach

7.4.1 Morphology

7.4.2 Anatomy

7.5 Frogs

7.5.1 Morphology

7.5.2 Anatomy

Earthworm, Cockroach and Frog show characteristic features in body organization. In Pheretima Posthuma (earthworm), the body is covered by a cuticle. All segments of its body are alike except the 14th, 15th and 16th segment, which are thick and dark and glandular, forming clitellum. A ring of S-shaped chitinous setae is found in each segment. These setae help in locomotion. On the ventral side, spermathecal openings are present in between the grooves of 5 and 6, 6 and 7, 7 and 8 and 8 and 9 segments. Female genital pores are present on the 14th segment and male genital pores on the 18th segment.

After going through Class 11 Biology Chapter 7 - Structural Organisation in Animals, you must be able to answer the following questions which are given below:

  • Q1. What are the cellular components of blood?
  • Q2. What are the following and where do you find them in the animal body.
    • (a) Chondrocytes
    • (b) Axons
    • (c) Ciliated epithelium
  • Q3. Mention the function of the following (a) Ureters in frog (b) Malpighian tubules (c) Body wall in earthworm

If you are unable to answer the following questions by yourself then, NCERT Solutions for Class 11 Biology Chapter 7 - Structural Organisation in Animals will help you to answer them by understanding the concept behind it.

Also, try to answer solve all the questions given in Chapter 7 - Structural Organisation in Animals of NCERT, as NCERT is the base of your educational knowledge.
