KINGDOMS (PLANTAE & ANIMALIA) 

CONTENT

  1. Kingdom Plantae
  2. Kingdom Animalia

 

Kingdom Plantae

(i) They are mainly non-motile

(ii) They are all autotrophic

 

1. Division Thallophyta (Algae):

E.g. pondweeds, seaweeds, diatoms

(a) They are nearly all aquatic

(b) Some are unicellular e.g. Chlamydomonas and diatoms some are filamentous e.g. spirogyra while some have flat body called a thallus e.g. seaweeds.

(c) The body is simple in structure. They have no true roots, stems, leaves or specialized conducting systems.

(d) All have chlorophyll and they photosynthesis. However, some have other pigments which mask the green colour of chlorophyll e.g. seaweeds may be brown, red, and green in colour.

2. Divisions of Embryophyta

(i) Bryophyta

E.g. mosses and liverworts.

(a) The cells are differentiated into tissues.

(b) They lack true roots stems and leaves, but have structures resembling them e.g. a typical moss has a stalk, small leaves which are one or two cells thick and thread-like rhizoids.
