Important Questions on Animal Tissue
Match the type of cells in Column with the organs they are part of, listed in Column
| Column | Column | ||
| P. | Chondroblast | i. | Bone |
| Q. | Osteoclast | ii. | Brain |
| R. | Microglia | iii. | Cartilage |
| S. | Pneumocyte | iv. | Lung |
Choose the CORRECT combination.
Study the following statements and identify the correct statements-
Microglial cells keep the cerebrospinal fluid in the ventricles of brain in constant circulation
Arrector pili muscles are unstriated muscles
Basophils remove antigen-antibody complexes from the blood
Perichondrium is absent in fibrous cartilage
| Connective tissue | Example | ||
| (A) | Dense regular connective tissue | (I) | Dermis |
| (B) | Dense irregular connective tissue | (II) | Whortan's Jelly |
| (C) | Elastic connective tissue | (III) | Lymphoid organs |
| (D) | Mucus connective tissue | (IV) | Tendon |
| (V) | Vocal cords |
The correct match is
Statement I : Tendons attach one bone with another bone.
Statement II : Epiglottis is formed by elastic cartilage.
The correct option among the following is
Give reason: Bone is stronger than cartilage.

(ii) They connect and support other tissues.
(iii) They include diverse tissues such as bones, cartilage, tendons, adipose, and other loose connective tissues.
(iv) They form the internal and external lining of many organs.
(v) In all connective tissues except blood, the cells secrete fibres of structural proteins like collagen and elastin.
