Question

you have just discovered a new organism. its cell has a nucleus,small vacuoles and a cell wall. how would you classify it.

Answer 1

While classifying an organism, the first thing you need to start from morphology (no need to go cellular level at first, even it is a unicellular organism). Here you need say how you find that it is new, this could be a new species of an existing living form. The cellular level mostlly help you to discriminate in a species level discrimination, you can use molecular level classification.

Answer 2

Since its cell has a nucleus so it must be a eukaryote. It also has a cell wall and vacuole so it must be plantae under eukaryotes.
