Protoctists and Prokarytoes

2.

Objectives
● to know the structure of a protoctist
● to know the structure of prokaryote
● to know the difference between a protoctist and a prokaryote

3.

Kingdom Protoctists
● Many members with different types
● Cell number
○ multicellular
○ unicellular
● Cell parts
○ nucleus
○ chloroplast

4.

Kingdom Protoctists
● Nutrition
○ eat ready food (like animals)
○ do photosynthesis (like plants)
○ both
● Members (Book page 16)
○ Amoeba
○ Euglena
○ Plasmodium
○ Algae

5.

Kingdom Prokaryotes
● Bacteria are example of prokaryotes
● Cell number
○ unicellular (single-celled)
● Cell part
○ no nucleus
○ no organelles
● Nutrition
○ mostly feed on ready food
○ few can do photosynthesis

6.

Kingdom Prokaryotes
● Parasites
○ feed on living organisms
● Saprotrophs
○ feed on dead organisms
● Size
○ very small (visible with high-powered microscope)
● Shape (Book page 17)
○ cocci (spherical)
○ bacilli (rod-shaped)
○ spirilli (spiral)
