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. Protistaare 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
