Question

Smallest cell organelles are:
A) Lysosomes
B) Sphaerosomes
C) Peroxisomes
D) Ribosomes

Answer 1

Hint: The cell is the primitive and primary unit for all living organisms, particularly in all eukaryotes the cell has multi organelles which function for cellular growth, energy production. Each organelle has their own structure and role to perform in cellular growth.

Complete Answer:
- The cell Consists of a multi organelle structure and these organelles are their own properties and functions in metabolism.
- However, Lysosomes are the membrane bound cell organelle that contains enzymes involved in absorbing nutrients and serving both to reduce material taken up from outside the cell and to digest obsolescent components of the cell itself.
- Spherosomes also are known as plant lysosomes, single half unit membranes covering small spherical organelles which synthesize and perform metabolism activities.
- Peroxisomes are considered as one of the cell organelles and it synthesizes lipids, cholesterol and dolichol are produced in peroxisomes as well as in the Endometric Reticulum. In the liver, peroxisomes are also involved in the synthesis of bile acids, which are derived from cholesterol.
- Ribosomes considered as the smallest organelle of the cell and associated with the outer layer of the cell wall, these are known as Protein factories, it plays a key role in Protein synthesis.

The appropriate answer for Smallest organelle is ‘’Ribosomes’’.

Note: Cell is composed of organelles which play a key role in metabolism, protein synthesis, generate energy, the largest organelle of the cell is the Nucleus and the smallest one is ribosomes.
