Try it on paper first. A hint, the key idea and the worked solution are here when you need them.
Name the kingdom of each: (a) Paramecium, (b) Penicillium, (c) a fern, (d) Nostoc, a blue-green alga, (e) an earthworm.
Whittaker's five kingdoms. Monera: no true nucleus, one cell. Protista: a nucleus, one cell. Fungi: a nucleus, a wall of chitin, feed on dead matter. Plantae: many cells, a wall of cellulose, make food. Animalia: many cells, no wall, get food from others.
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
(a) Paramecium: one cell with a nucleus. Protista.
(b) Penicillium: a mould with a wall of chitin, feeding on dead matter. Fungi.
(c) A fern: many cells, a wall of cellulose, makes food. Plantae.
(d) Nostoc: no true nucleus. Monera.
(e) An earthworm: many cells, no wall, eats other things. Animalia.
