A.It shows relationships and patterns among organisms.

B.It removes the need to observe organisms.

C.It proves that all organisms are identical.

D.It prevents scientists from discovering new species.

A.Whether they live on land only

B.Eukaryotic or prokaryotic cell organisation

C.Whether they are visible from space

Question 3mcq

Why is mode of nutrition useful in classification?

A.It shows the exact age of every organism.

B.It proves all organisms have the same body plan.

Why are bacteria placed separately from Protista in the five-kingdom system?

A.Bacteria are always multicellular animals.

B.Protists never contain cells.

Question 11mcq

Why are scientific names useful even when local names are different?

A.They change from village to village.

B.They are based only on the organism’s colour.

C.They provide a common international name for the same organism.

D.They prevent scientists from comparing organisms.

Question 12mcq

A local name refers to different plants in two regions. What should a student use to avoid confusion?

A.Only the colour of the flower

B.Only the shop name

C.A nickname made by the class

D.The scientific name

Section C: Groups and Names Review

Question 13mcq
