Basis of Modern Classification System
The modern
definition of classification groups depends upon each species
in the group
evolving from a single ancestral type with the basic group
characteristics -
plants all share an ancestor that had true plant
characteristics, but the
ancestor they share with fungi is neither distinctly plant or fungus, so they
have been designated into different
Kingdoms. Based upon this criteria, many
zoologists think that the Animal
Kingdom should be splintered into at least two
Kingdoms. The Protista and
the Monera are often "made up" of multiple Kingdoms
in advanced books on
the subjects.

Species
Plants
1. all organisms have tissues, but not all have tissues that conduct water 2. most use chlorophyll to manufacture food 3. cells are surrounded by cell walls which contain cellulose 4. reproduce with spores, seeds, or asexually |
Archaebacteria
1. unicellular 2. live in extreme conditions 3. lack membrane bound internal structures. main difference between |
Fungi
1. some are unicellular, but most are colonial 2. lack chlorophyll, so they cannot make their own food 3. obtain food by secreting enzymes to digest substances which they then absorb |
Protists
1. either unicellular or colonial, none produce true tissues 2. algae contain chlorophyll and can produce their own food 3. protozoans obtain food from other sources |
