Chapter 8 Flashcards
What is biodiversity?
The variety of living organisms such as microorganisms,animal,plant that interact with one another
List taxonomic classification system
•Classification
•Identification
•Naming
-using bionomial nomenclature system
Six types of organisms
- Archaebacteria
- Eubacteria
- Protista
- Fungi
- Plantae
- Animalia

What is prokaryote?
A type of cell which lack a membrane bound nucleus
What is Eukaryote?
•Has a nucleus and membrane enclosed organelles
What is Heterotroph?
•An organisma that can’t synthesis its own food but obtain food molecules by eating other organism
What is autotroph?
•An organism that can synthesise its own food by organic materials by using light energy or chemical energy
Three groups of archaebacteria?
Methanogen,Halophile,Thermophile
What is methanogen?
•Anaerobic bacteria are found in swamps and the digestive tract of ruminants and humans.
Produces methane as a metabolic by product.
What is halophile in archaebacteria?
•Found in places with extremely high salt concentration,such as Dead Sea
What is Thermophile in archaebacteria?
- bacteria that can withstand high temperature at an optimum temp of 60°c to 80°c.
- Found in hot springs and highly acidic locations
Archaebacteria have peptidoglycan or not?
Not have peptidoglycan
Cell wall of Eubacteria is?
Cell wall of Eubacteria made of peptidoglycan
What is peptidoglycan?
•known as murein which is a polymer made up of sugars and amino acids.
Explain cytoplasm of eubacteria?
•contains ribosome and plasmids but has none of the membrane-enclosed organelles like mitochondria,endoplasmic reticulum
Protista is simplest or complex tissue?
•has a simple cell without specialised tissues
Three groups of protista is …
•protozoa,algae,slime mould
explain plantae
- can synthesis food via chlorophyll
* can undergi asexual reproduction
Hierarchy system used in taxonomy is
Linnaeus hierarchy system
Acronym order of hierarchy;
- Dodol-domain
- Kelapa-Kingdom
- Parut-Phylum
- Cuma-Class
- Order-Order
- For-Family
- Gathering-genius
- sahaja-species
