Question 3mcq

Why is mode of nutrition useful in classification?

Question 6mcq

Why is a mushroom not classified as a plant?

Question 11mcq

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

A.They change from village to village.

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

C.They prevent scientists from comparing organisms.

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

Question 12mcq

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

A.The scientific name

B.A nickname made by the class
