Which of the following structures is the functional unit in a Golgi complex? Correct Answer Cisternae

The correct answer is Cisternae.

Key Points

Explanation:

  • Camillo Golgi (1898) first observed densely stained reticular structures near the nucleus. These were later named Golgi bodies after him.
  • They consist of many flat, disc-shaped sacs or cisternae of 0.5μm to 1.0μm diameter.
  • These are stacked parallel to each other. A varied number of cisternae are present in a Golgi complex.
  • The Cisternae is the functional unit in a Golgi complex
  • The Golgi cisternae are concentrically arranged near the nucleus with distinct convex cis or the forming face and concave trans or the maturing face.
  • The cis and the trans faces of the organelle are entirely different but interconnected.
  • The Golgi apparatus principally performs the function of packaging materials, to be delivered either to the intracellular targets or secreted outside the cell.
  • Materials to be packaged in the form of vesicles from the ER fuse with the cis face of the Golgi apparatus and move towards the maturing face.

Additional Information 

Thylakoid
  • Thylakoids are membrane-bound compartments inside chloroplasts and cyanobacteria.
  • Thylakoids are the site of the light-dependent reactions of photosynthesis.
Cristae
  • Mitochondria is is a double-layered cell organelle, in which the outer layer is porous and the inner layer is folded upon itself is known to be ''cristae''
  • The cristae increase the surface area.
Archoplasm
  • The protoplasmic material which surrounds the centrosome is called archoplasm

Consider the following four relational schemas. For each schema, all non-trivial functional dependencies are listed. The underlined attributes are the respective primary keys. Schema I: Field ‘courses’ is a set-valued attribute containing the set of courses a student has registered for. Non-trivial functional dependency: rollno → courses Schema II: Non-trivial functional dependencies: rollno, courseid → email email → rollno Schema III: Non-trivial functional dependencies: rollno, courseid → marks, grade marks → grade Schema IV: Non-trivial functional dependencies: rollno, courseid → credit courseid → credit Which one of the relational schemas above is in 3NF but not in BCNF?
