Inhoud

AKTIWITEIT: Om diere volgens kenmerke te klassifisseer [LU 2.2]

Diere met ‘n ruggraat of werwelkolom en ‘n inwendige geraamte (endoskelet) word in een groep geplaas en diere sonder ‘n ruggraat of werwelkolom word in ‘n ander groep geplaas. Die groep met ‘n werwelkolom word gewerwelde diere of Vertebrata genoem. Die groep sonder ‘n werwelkolom of ruggraat word die ongewerwelde diere of Invertebrata genoem. Sommige van die Invertebrata se liggame word deur ‘n harde dop buite-om beskerm, bv. die krap of die sprinkaan. Hierdie harde dop word die uitwendige geraamte of ‘n eksoskelet genoem.

Die onderstaande diagram toon aan hoe diere volgens bepaalde kenmerke ingedeel word:

‘n Interessante vraag: Swamme is nie as deel van die plante of diere aangetoon nie. Probeer uitvind waar hulle hoort.

Opdrag 4:

(i) Kriteria vir sortering van Vertebrate

Werweldiere kan na aanleiding van hul tipe liggaamsbedekking gesorteer word.

Opdrag 5:

Raadpleeg weer die diagram en stel die onderskeie werweldiere met hul spesifieke liggaamsbedekking diagrammaties voor. Wees kreatief en gebruik illustrasies, asook woorde.
