1. Organelle formation from scratch. Membrane bound cellular organelles such as peroxisomes, mitochondria, and endoplasmic reticulum (ER) have protein machineries that allow selective protein import and organelle proliferation.

Q1. Body is formed of cells, cells are formed of Organelles but how Organelles formed?
Answer:
•Cell Organelles like mitochondria and chloroplast being formed due to endosymbiosis,other organelles were formed due to proteins and phospholipids.
★Endosymbiosis:
The symbiotic relationship of an eukaryotic cell and a prokaryotic cell is called as ENDOSYMBIOSIS.
•It is theorized that mitochondria and chloroplast were a prokaryotic cell and they entered an eukaryotic cell for nutrition and shelter respectively.
•Organelles like Golgi complex and ER are made of proteins.
Q2. Life started from chemistry, then how chemistry turned into living beings which we today study as biology?
Answer:
★First,let me introduce you to Physical Biological Hierarchy.
It follows like this,
Atoms&Molecules
↓
Compounds
↓
Cells
↓
Tissues
↓
Organs
↓
Organ System
↓
Organisms
•It is observed that a life causing reaction occurs at the cellular level, subsequently evolving unicellular and multicellular organisms.
•It is well known that all the organisms are made of DNA and RNA which are nucleic acids
•An unicellular bacterium evolves into a multicellular organism,still evolving into a complex multicellular organism.
