Question

what are some drawbacks to calssification

Answer 1

Two drawbacks in classifying organisms under the old one two Kingdom classification are:-
1.'Bacteria and fungi are plants'- they have no chlorophyll and do not carry out photosynthesis.
2.Some single-celled organisms such as Euglena cannot be exclusively called plant or animal - they have chloroplasts like the plants. have cell mouth to feed like animals and possess contractile vacuole for excretion .

Answer 2

The backwards in classification are:

1. Many unicellular organisms like
chlamydomonas were classified
together with multicellular organisms
like higher plants.

2. Prokaryotes like bacterias were
classified along with eukaryotes
even though they are totally different.

3. Fungi was placed with higher plants
just because it possesses cell wall like
plants whereas unlike plants it didn't
perform photosynthesis.

4. Bacteria and fungi are plants they
have no chlorophyll and do not carry
out photosynthesis.

5.Some single-celled organisms such
as Euglena cannot be exclusively called
plant or animal they have chloroplasts
like the plants. have cell mouth to feed
like animals and possess contractile
vacuole for excretion.
