•  Prostate glands
•  Albumin glands
•  Accessory glands
•  Mucous glands

Solution
In Pheretima,accessory glands help in binding the worms the during copulation.

Q2.Tissue level of organisation is seen in

•  Platyhelminthes
•  Chordata
•  Arthropoda
•  None of these

Solution
Tissue level organisation is seen in phylum_Coelenterata and Ctenophora

Q3.  When the body is externally and internally divided into segments,it is called

•   True segmentation
•  False segmentation
•  Pseudo segmentation
•  Asegmentation

Solution
Metamerism or true segmentation is seen when the body is externally and internally divided into segments

Q4. In Leucosolenia,gametes develop from

•  Amoebocytes
•  Archaeocytes
•  Choanocytes
•  Myocytes

Solution
∵ In Leucosolenia,archaeocytes give rise to the sex cells(ova and sperms) and play an important role in registration.

•  Sycon – Canal system
•  Starfish – Radial symmetry
•  Ascaris – Flame cell
•  Prawn - Haemocoel

Solution
  Flame cells are excretory organ of Platyhelminthes. The excretory organ of Ascaris is protonephridia.

Q6. Mollusca is

•  Triploblastic, Acoelomate
•  Triploblastic, coelomate
•  Diploblastic, Acoelomate
•  Diploblastic, coelomate

Solution
Phylum_Mollusca is the second largest phylum of animals.These are mostly aqutic,triploblastic,coelomate animals with organ system level of organisation.

Q7.Which of the following is a monogenetic parasite?

•  Taenia solium
•  Ascaris
•  Fasciola hepatica
•  Plasmodium vivax

Solution
Ascaris is monogenetic parasite with no intermediate host.

Q8.Thigmotaxis is not shown by

•  Paramecium
•  Amoeba
•  Ascaris
•  Hydra

Solution
Ascaris do not show thigmotaxis.

Q9.Earthworms have no skeleton, but during burrowing the anterior end becomes turgid and acts as a Hydraulic skeleton. It is due to

•  Coelomic fluid
•  Blood
•  Gut peristalsis
•  setae

Solution
The body cavity (coelom) of earthworm is filled with an alkaline, colourless or milky coelomic fluid containing water, salts, some proteins and four types of coelomic corpuscles. During burrowing and locomotion, contraction of septa (which partioned coelom into series of coelomic chambers) increases pressure on coelomic fluid, thus making the anterior body segment turgid and elongated.

Q10. Nematoblasts of Hydra are

•  Sensory
•  Complicated
•  With nematocyst apparatus
•  All of the above

Solution
Nematoblasts (cnidoblasts) are sensory in nature and acts as a organ for offence and defence.
