The 5 Kingdoms:
1. Prokaryota
No Nucleus
Plasmids (a loop of DNA)
No membrane bound organelles
Smaller organisms, smaller Ribosome
Parasite, causes diseases
Respiration in mesosomes
2. Protocists (Protoctista)
Eukaryotes (Nucleus and membrane bound organelles)
Mostly singlecelled
Mostly freeliving
Some are parasites
Doesn't fit into the other 4 kingdoms
3. Fungi
Eukaryotes
Mycelium consists of hyphae
Walls are made of chitin (polysaccharide)
Some are Saprophytic (they feed of dead organisms)
4. Plants (Plantae)
Multicelluar
Nutrition is gained through Photosynthesis
Cellulose cell wall
Produce multicellular embryos

Endangered species: Species that have such low numbers that they are at risk of
extinction. There is very little genetic variation, so there is an increased susceptibility to
diseases.

Dichotomous keys: helps provide a way to identify organisms based on observational
features.
Adaptations increase organism's chances of survival and reproduction.
