2.  It is the arrangement of organism or
group of organism into distinct
categories
 It is based on similarities and
dissimilarities among the organism.

3.  To know various kind of plants on the
earth with names, geographical
distribution, characteristic and their
economic importance.
 To ascertain nomenclature
 To know phylogenetic relation

5.  Complexity of cell structure
 Complexity of organisms
 Mode of nutrition
 Life style
 Phylogenetic relationship

6.  They are unicellular.
 They may be autotrophic or heterotrophic.
 These are prokaryotic cells without
distinct nucleus or cell organelles.

9.  Protista are unicellular with defined
nucleus.
 Have pseudopodia or hair like cilia or
whip like flagella for locomotion.
 Autotrophs – eg. euglena, volvox
 Heterotrophs – eg. Amoeba, Paramoecium

11.  These are non- green, eukaryotic,
heterotrophic organisms.
 They are saprotrophs.
 Have cell wall of chitin.
 Eg – Apergillus, Mushrooms,
Penecillium

14.  Unicellular, parasitic organism.
 Bacterial cell is prokaryotic with cell wall, but
nucleus and cell organelles are absent.
 Reproduce by binary fission.
 They can double in number in 20 mins.
 Size – 1µm to 10 µm

15. Bacillus Spirillum

16.  Unicellular with eukaryotic cell
 Found in soil, fresh water and sea water.
 Variation in structure.
 Reproduction by cell division
 Eg – Amoeba, Paramoecium
 Euglena- autotrophic
 Size - 200µm

19.  They are aquatic
 Eukaryotic, unicellular, autotrophic
 Eg- chlorella, chlamdomonas
 Size - 10µm to 100µm

21. Chlorella

22.  Smaller than bacteria.
 Found in the form of independent particle. It’s
a long molecule of DNA or RNA covered in a
protein coat.
 They can survive in living system.
 And able to cause diseases.
 Size - 10nm to 100nm
