CLASSIFICATION

-Classification: is the grouping of organisms based on their similarities and differences.

RANKS OF CLASSIFICATION

-There are seven (7) ranks of classification which are:

1. Kingdom……..the highest rank

2. Phylum or division

3. Class

4. Order

5. Family

6. Genus

7. Species……….the lowest rank.

TYPES OF CLASSIFICATION

-There are two types of classification which are:

1.​​ Natural classification:​​ is the grouping of organisms based on many features in common.

2.​​ Artificial classification:​​ is the grouping of organisms based on few features especial observed features.

*TAXONOMY: is the study which deals with the identification, naming and classification of organisms.

*NOMENCLATURE: is the system of giving scientific names to the organisms.

*BINOMIAL NOMENCLATURE: is scientific way of naming organisms where by each organism has one scientific name with two parts, the generic name and the specific name.

In biology, organisms are classified into five major groups called kingdoms.

These groups are:

1. Kingdom monera.eg bacteria

2. Kingdom protoctista.eg amoeba

3. Kingdom fungi.eg mushroom

4. Kingdom plantae.eg maize

5. Kingdom animalia.eg human being

–According to NECTA, different questions of biology practical in classification are based on the last three kingdom: Kingdom fungi, ​​ Kingdom plantae, and Kingdom animalia.

  1. Thanks for some other informative blog. Where else may just I am getting that kind of information written in such an ideal method? I’ve a undertaking that I am simply now operating on, and I’ve been at the look out for such information.

  2. Hello, you used to write fantastic, but the last several posts have been kinda boring?K I miss your great writings. Past several posts are just a bit out of track! come on!
