SPM Biologi- Bidang Biologi dan Kerjaya

11/19/2022

Bidang Biologi dan Kerjaya

Biologi adalah kajian terhadapa benda hidup dan persekitaran semula jadi secara terperinci dan menyeluruh.

Istilah “Biologi” terbahagi kepada dua bahagian iaitu bios dan logos.

Bios dan logos merupakan istilah dalam Bahasa Yunani yang membawa maksud:
Bios-kehidupan
Logos – kajian

Bidang – bidang kajian yang berkembang daripada biologi adalah:
kajian berkaitan tentang benda hidup
-botani, mikrobiologi, entomologi dan zoology
Kajian berkaitan tentang persekitaran dan organisma
-ekologi dan biogeografi
kajian tentang pengunaan biologi/ aplikasi biologi
-perubatan, pergigian dan farmasi
Kajian tentang struktur dan funngsi benda hidup/ organisma
Anatomi, fisiologi, sitologi dan histiologi.

Kerjaya Dalam Bidang Biologi
-pakar biologi
-doktor
-doktor gigi
-ahli farmasi
-jurutera genetic
-jururawat
-pakar ekologi
