1.Domain is divided into eukaryotic and prokaryotic.
Prokaryotic is the organisms that doesn't have nucleus membrane.
(monera kingdom)
Eukaryotic is the organisms that has nucleus membrane.
(fungi, protozoa, animalia & plantae kingdoms)

(a) Monera Kingdom:
-Are unicelluar organisms that doesn't have nucleus membrane.
-Divided into archeabacteria, eubacteria and cyanobacteria.

(b) Protosista/Protozoa Kingdom:
-Most are unicelluar
-Some multicelluar
-Some autotrophic and some heterotrophic
-Aquatic

(c) Fungi:
-Multicelluar, except one, yeast
-Absorptive heterotrophs
-Cell walls made of chitin

(d) Plantae:
-Multicelluar
-Autotrophic
-Absorb sunlight
-Do photosynthesis

(e) Animalia:
-Multicelluar
-Heterotrophs
-Feed on animals and plants
