Option "D" is incorrect.

Option "A" is correct.

  • ER always forms a network system.

  • It is large network of membrane bound sheets and tubes.

  • Ribosomes present at the RER acts as the site of protien synthesis.

  • SER helps in the synthesis of Lipids and fats which then helps in bulilding Plasma membrane. This Process is known as Member biogenesis.

  • Some other lipids and Protien functions as enzymes and Hormones.

  • It also Provide surface for some Biochemical activities.

  • It also serve as a channel for transportation of material between cytoplasm and nucleus.

option "B" is also correct.

  • Golgi appratus helps in the formation of Lysosomes.

  • During the disturbance of cellular metabolism or when the cell get damaged it may burst and digest their own cell.

  • Lysosomes are kind of waste disposal system of the cell, it helps in cleaning the cell by digest foreign material as well as worn out cell Organelles.

  • All the bacterias, microorganisms and Foreign materials end up in Lysosomes.

Option "c" is also correct.

  • Mitochondria is known as powerhouse of the cell as it helps in respiration.

  • When the mitochondria needed energy for making new chemical compound and for mechanical work the ATP molecules breaks down to provide energy

  • They are strange Organelles because they have their own DNA and Ribosomes.
