INDIAN SCHOOL AL WADI AL KABIR Class: IX DEPARTMENT OF SCIENCE 2024-25 DATE: 13-11-2024 SUBJECT: BIOLOGY WORKSHEET TOPIC: ANIMAL TISSUE A4 FILE NO: 4 WITH FORMAT ANSWERS (PORTFOLIO) CLASS & SEC NAME OF THE STUDENT: ROLL NO. I. OBJECTIVE TYPE QUESTIONS: 1. The Esophagus and lining of mouth are covered with: a) Squamous epithelium b) Columnar epithelium c) Cuboidal epithelium d) Connective tissue 2. Two bones are connected together by: a) Tendons b) Ligaments c) Plasma d) Cartilage 3. The fat storing connective tissue present under skin is: a) Areolar b) Adipose c) Adrenals d) Cartilage 4. ___________ is a striated and involuntary muscle. a) Cardiac muscle b) Skeletal muscles c) Smooth muscles d) Striated muscles 5. The matrix is fluid in which connective tissue? a) Areolar b) Adipose c) Cartilage d) Blood Page 1 of 7  For the questions 6 to 10, two statements are given-one labelled Assertion (A) and the other labelled Reason(R). Select the correct answer to these questions from the options (i), (ii), (iii) and (iv)as given below: i) Both A and R are true, and R is the correct explanation of the assertion. ii) Both A and R are true, but R is not the correct explanation of the assertion. iii) A is true but R is false. iv) A is false but R is true. 6. Assertion (A): Bone is a connective tissue which is very hard and rigid. Reason (R): The matrix consists of calcium and phosphate. 7. Assertion (A): Epithelium have only a small amount of cementing material between them and almost no intercellular spaces. Reason (R): Anything entering or leaving the body must cross at least one layer of epithelium. 8. Assertion (A): Skin epithelial cells are arranged in a single layer. Reason (R): Skin epithelium prevent wear and tear. 9. Assertion (A): Two bones can be connected to each other by another type of connective tissue called the Ligaments. Reason (R): This tissue is not elastic. It has considerably less strength. 10. Assertion (A): The functional combination of nerve and muscle tissue is not fundamental to most animals. Reason (R): This combination able animals to move rapidly in response to stimuli. II. SHORT ANSWER TYPE QUESTIONS (2M): 11. Identify the tissue: a) That has an ability to respond to stimuli. b) Fat storing adipose tissue. 12. Name the connective tissue that has hard matrix. What is its importance? 13. Identify the tissue in the figure given below and write its function. 14. Why are skeletal muscles called voluntary muscles? 15. What does a neuron consist off? Page 2 of 7 III. SHORT ANSWER TYPE QUESTIONS (3 M): 16. Observe the given figure and answer the following questions- i) Identify the tissue given in the figure ii) Mention the characteristic features of these cells. iii) Specify the function of this tissue. iv) Name the part of the body where these tissues are present. 17. Name the different components of the fluid connective tissue. Write two functions of the same. 18. Tabulate the skeletal muscles, smooth muscles and the cardiac muscles under the following headings: i) Location ii) function iii) Shape 19. Draw a well labelled diagram of a nerve cell and write down the composition of a nervous tissue. 20. Write down the location, structure and function of columnar epithelium tissue. IV. LONG ANSWER TYPE QUESTIONS (5M): 21. (i) Distinguish between bone and cartilage. (ii) What is the importance of ligament? (iii) Why is connective tissue known so? 22. What is a neuron? Write the structure and functions of a neuron. 23. Briefly describe striated and smooth muscles with their functions 24. With the help of labelled diagrams differentiate between striated muscles, unstriated muscles and cardia muscles? Page 3 of 7 V. CASE STUDY-BASED QUESTIONS You have more than 600 muscles in your body that you use almost constantly. Some move your body — others help your internal organs keep you alive. It’s OK to feel the occasional ache or muscle pain, but don’t ignore chronic (long-term) soreness or weakness. Muscles are pieces of soft tissue throughout your body. They help you do everything from holding your body still to running a marathon. Muscles also move and support your organs. Your heart is a hard-working muscle that beats thousands of times a day to keep you alive. 25. A. Name the location and function of the muscle you can control. OR B. Name the hard-working muscle that beats thousands of times a day. What are its characteristic features? C. Name the muscles which are under your control. D. This muscle is pointed at the ends, and has a prominent nucleus in the center of the cell.

II. SHORT ANSWER TYPE QUESTIONS (2 MARKS) 11 a) Nervous tissue b) Adipose tissue 12 Bone – It forms the framework that supports the body. It also anchors the muscles and supports the main organs of the body. 13 Areolar connective tissue. It fills the space inside the organs, supports internal organs and helps in repair of tissues. 14 as they are mostly attached to bones and help in body movement. 15 A neuron consists of a cell body with a nucleus and cytoplasm, from which long thin hair-like parts arise. Usually each neuron has a single long part, called the axon, and many short, branched parts called dendrites. III.
