The introduction of the Four-Year Undergraduate Programme (FYUGP) under the Choice Based Credit System (CBCS) has streamlined the undergraduate curriculum across Bihar’s top universities. 4-th Year undergraduate System For students pursuing a Bachelor of Science in Zoology at Patna University, Patliputra University, Tilka Manjhi, Lalit Narayan Mithila University or Babasaheb Bhimrao Ambedkar Bihar University (BRABU), Ranchi University and other state university MJC-1 (Major Course 1) focuses directly on the Diversity of Non-Chordates. This core paper builds your foundational understanding of lower invertebrate phyla, spanning from Protozoa to Hemichordata. The question is from all unit section.

Top 20 Important Short Questions from previous year:

Q1. Cyclosis in Paramecium: Explain the process of streaming movement of cytoplasm (cyclosis) in Paramecium?

Answer: 

Cyclosis is the continuous movement of cytoplasm inside the cell.

The cytoplasm moves in a circular/streaming manner.

This movement is mainly caused by the activity of cytoplasmic fibres.

It helps in the distribution of food, oxygen and other materials inside the body.

Cytoplasm continuously flows inside Paramecium, helping in the movement and distribution of materials.

STREAMING MOVEMENT OF CYTOPLASM (CYCLOSIS) IN PARAMECIUM

• Cyclosis is the continuous streaming or movement of cytoplasm inside the body of Paramecium.

• The cytoplasm is divided into ectoplasm and endoplasm.

• The endoplasm shows a slow and continuous streaming movement.

• The cytoplasm moves in a definite direction and forms a continuous circulation.

• This movement is caused by the activity of cytoplasmic fibres and contractile elements.

• Cyclosis helps in the distribution of digested food to different parts of the body.

• It helps in the movement of nutrients and oxygen within the cell.

• It also helps in carrying waste materials towards the places from where they are removed.

• It helps in maintaining proper cell activities.

• Thus, cyclosis is important for the internal transport and distribution of materials in Paramecium.

Easy Definition:

Cyclosis is the streaming movement of cytoplasm that helps in the transport and distribution of materials inside Paramecium.
