Cockroach – Excretory System
-
Excretion in cockroach is performed by all, EXCEPT:Excretion in cockroach is performed by Malpighian tubules, fat body, nephrocytes, cuticle and urecose glands. Hepatic (gastric) caeca, a ring of 6-8 blind tubules at the junction of foregut and midgut, secrete digestive juice.
Epithelial tissue
-
Which of the following types of epithelium is present in the bronchioles and Fallopian tubes?Ciliated epithelium lines the inner surface of hollow organs like bronchioles and Fallopian tubes.
Muscle tissue
-
Choose the correct statement about a muscular tissue:Smooth muscles are uninucleate and involuntary; skeletal muscle fibres are multinucleate and bundled in parallel. Gap junctions at the intercalated discs of cardiac muscle allow the cells to contract as a unit. Blood vessel walls are lined by simple squamous epithelium.
Cockroach - digestive and excretory organs
-
Match List - I with List - II regarding the organs of Cockroach. Choose the correct answer.
Pick the matching item from Column II for each row.
Column I
- A. Crop
- B. Proventriculus
- C. Hepatic caecae
- D. Malpighian tubules
Column II
- I. grinding the food particles
- II. secretion of digestive juice
- III. removal of nitrogenous waste
- IV. storage of food
Correct answer: A → IV, B → I, C → II, D → III
Crop - storage of food; Proventriculus (gizzard) - grinding of food particles; Hepatic caecae - secretion of digestive juice; Malpighian tubules - removal of nitrogenous waste.
Connective tissue
-
Choose the correct statements: (a) Bones support and protect softer tissues and organs (b) Weight bearing function is served by limb bones (c) Ligament is the site of production of blood (d) Adipose tissue is specialised to store fats. (e) Tendons attach one bone to another. Choose the most appropriate answer from the options given below(c) is false: blood cells are produced in the bone marrow, not ligaments. (e) is false: ligaments join bone to bone, while tendons attach muscle to bone. (a), (b) and (d) are correct.
