Question

A scientist determined that a single celled organism has a membrane bound nucleus and organelles. The organism has a cell membrane and a cell wall composed of cellulose. In which kingdom does this organism belong.

Answer 1

Answer:

Protista

Explanation:

1. Firstly, it cannot be bacteria because bacteria is prokaryotic with no membrane bound organelles. And it's cell wall is made of murein (peptidoglycan).
2. It certainly isn't a virus virus because a virus has no true cellular structure.
3. Let's see why we ruled out the other 3 eukaryotic kingdoms:

• It can't be an animal because animal cells don't have cell walls and are multicellular.
• It can't be fungi because its cell wall is made of chitin, not cellulose.
• It can't be a plant because plants are all multicellular.
