Identify the larval stages in the development of liver fluke
1 Veliger, Trochophore, Sporocyst, Planula
2 Sporocyst, Planula, Trochophore, Redia
3 Miracidium, Sporocyst, Redia, Cercaria
4 Planula, Sporocyst, Muller, Trochophore
Explanation:
C Larval stages in the development of liver fluke- Miracidium Larva- Its outer surface has 21 chitinous plate arranged in 5 rows. Outer surface is ciliated excluding anterior most apical end. - A large number of germ cells are present which develops next larval form-sporocyst larva. - Miracidium larva is more advanced than its adults due to the presence of locomotary cilia and sensory brain and eye. Sprocyst Larva- It is inside the snail body. It is simplest larval form of fasciola. First larva in snail alimentary canal which comes out by breaking of outer wall of miracidium larva. Redia Larva- Redia larva develop next larval stage. Cercarial form germ balls present inside their body. Cercaria Larva- About 10-42 carcavia larva develops from single redia larva. Alimentary canal or gut becomes inverted U-shaped with mouth opening and muscular pharynx.

Assertion (A): Protonephridia are found in lancelet. Reason (R): Protonephridia are primarily concerned with excretion. The correct option among the following is:
1 (A) is true. (R) is true and (R) is the correct explanation for $(\mathrm{A})$
2 (A) is true. (R) is true but (R) is not the correct explanation for (A)
3 (A) is true but (R) is false
4 (A) is false but (R) is true
Explanation:
C Protonephridia are found in the phylum Platyhelminthes. Bundle of flame cells are called protonephridia. It is a network of dead-end tubules connected to an external opening. These tubules excrete dilute fluids and function in osmoregulation.

Animal of which phylum have hooks and suckers and are endoparasite on other animals
1 Platyhelminthes
2 Annelida
3 Aschleminthes
4 Arthropoda
Explanation:
A Platyhelminthes or flatworm are mostly endoparasites found in animals. They contain hooks and sucker that allow them to directly receive nutrients from the host via the surface of their body. eg:- Taenia (Tape worm), Fasciola (Liver-fluke).

In which triploblastic animal, coelom is absent?
1 Platyhelminthes
2 Aschelminthes
3 Annelids
4 Arthropoda
Explanation:
A The members of phylum Platyhelminthes are acoelomate and triploblastic i.e. lacking a body cavity. The special mesodermal tissue called mesenchyma fills the gaps between the organs.

Explanation:
B The phylum Platyhelminthes contains flame cells. It is a specialized excretory cells that assist Playtehelminthes in excretion. Flame cells are also known as solenocytes.
