The document discusses cells and their classification. It states that cells are the fundamental unit of all organisms, and that organisms can be either unicellular or multicellular. It provides background on early scientists like Hooke, Leeuwenhoek, and Schleiden who observed and described cells. It also distinguishes between prokaryotic and eukaryotic cells, giving bacteria as an example of prokaryotes and noting some of their distinguishing characteristics.

2.  Cell is the fundamental unit of all
organisms
 All organisms are composed of
cell.
 Organisms having a single cell is
called unicellular organisms
 Multicellular organisms are made
of many cells

3.  Father of microbiologist
 First saw and described a living
cell
 Robert hook observed first a cell
 Leeuwenhoek discovered a single
celled organism(protozoan) he
called them as “animacules”

5.  German botanist
 All plants are made of cells

6.  British zoologist

22.  Represented by bacteria, blue green algae,
mycoplasma and PPLO.
 They multiply morerapidly than eukaryotic
cell
 The four basic shapes of bacteria are bacillus,
coccus, vibrio, and spirillum

33.  Ribosomes are non membrane bound
organelle found in both prokaryotes and
eukaryotes
 Sites of protein synthesis
