The study of living thingsis Biology
What is Life?
![Page 3: Lecture 1 2014](https://reader036.vdocuments.us/reader036/viewer/2022062313/55847ef1d8b42aa4028b4752/html5/thumbnails/3.jpg)
“Life” is an outcome of ancient events by which nonliving matter-atoms and molecules became assembled into the first living cells
Atom
Molecule
Cell:The cell is the smallest unit of life
Tissue: Organized array of cells
Organ:Structural unit of interacting tissues
Organ system:Structural unit of interacting organs

“Life” is a way of capturing and using energy and raw materials.

“Life” is a capacity to reproduce, grow and develop
DNA is the blueprint of life

Bacteria Archaea
Bacteria are the most numerous organisms on the planet. All are single-celled, but different types vary in shape and size.
Archaea do not have a nucleus but differ from bacteria in some biochemical aspects and are more closer to eukaryotes.
