  Single Celled

  Free living, commensal or parasitic
• The plasma / cell membrane is modified in some protists, helps give rigidity
• What is the alveoli?

  Membranes that form sacs
• What is the glycolax?

  Glycoprotein surface coat
• What is the mitochondrea shaped like?

  Can either be tubular or have branched cistrae

  
• What is their nuclei like?

  Has a micro and a macronucleus

  
• Flagella?

  composed of a central axoneme, originates from the kinetoplast (kDNA)
• Cilia?

  Similar to flagella, found throughout the body
• Pseudopodia?

  Found in amoebas, function in movement and feeding
• How does asexual reproduction occur in amoebas?

  Flagella: Longitudinal

  Transversally: Flagellates
• Where does multiple fission occur in?

  Amoebas and apicomplexa

  results in multiple daughter cells

  
• What does the fusion of a macro-gamete and a micro-gamete result in?

  Zygote, when nuclei come together it is known as conjugation
• Where does conjugation occur?

  In ciliates only
• What cyst?

  Resistant covering, prevents drying and other harsh conditions. Locomotor is reabsorbed, nuclei division can occur
