Animal Tissues – Connective Tissue
-
Given below are two statements: Statement I: Ligaments are dense irregular tissue Statement II: Cartilage is dense regular tissue. In the light of above statements choose the correct answer from the option given below:
Ligaments are dense regular connective tissue and cartilage is a specialised connective tissue, so both statements are false.
Ligaments are dense regular connective tissue that connect bone to bone. Cartilage is one of the types of specialised connective tissues.
Cockroach – Morphology
-
Which of the following is characteristic feature of cockroach regarding sexual dimorphism?
Anal styles are present only in the male cockroach.
Anal styles are paired, short, unjointed structure present only in male and help in sexual dimorphism.
Animal Tissues – Epithelial and Connective Tissue
-
Match List-I with List-II.
Pick the matching item from Column II for each row.
Column I
- A. Mast cells
- B. Inner surface of bronchiole
- C. Blood
- D. Tubular parts of nephron
Column II
- I. Ciliated epithelium
- II. Areolar connective tissue
- III. Cuboidal epithelium
- IV. specialised connective tissue
Correct answer: A → II, B → I, C → IV, D → III
Mast cells lie in areolar tissue, bronchioles have ciliated epithelium, blood is specialised connective tissue, and nephron tubules have cuboidal epithelium.
Mast cells – Areolar tissue serves as support frame work for epithelium. Inner surface of bronchiole – Ciliated epithelium bear cilia on their free surface that help to move particles in specific direction. Blood – Specialised connective tissues. Tubular parts of nephrons – Cuboidal epithelium help in secretion and absorption.
Cockroach – Excretory System
-
In cockroach, excretion is brought about by- A. Phallic gland B. Urecose gland C. Nephrocytes D. Fat body E. Collaterial glands Choose the correct answer from the options given below:
Cockroach excretion involves the fat body, nephrocytes and urecose glands.
Insects like cockroach are uricotelic (excrete uric acid). In addition, the fat body, nephrocytes and urecose glands also help in excretion.
That is every question in Structural Organisation in Animals for this filter.
