COMPREHENSIVE ASSESSMENT SCRIPT
SOLVED QUESTIONS ANSWERS UPDATED
REVIEW SET
◉ contractile vacuoles.
Answer: Organelle that moves water in and out of cell for osmotic
regulation
◉ klinetoplastids.
Answer: May have no mitochondria at all or may have modified
mitochondria
◉ Holozoic.
Answer: Feed upon whole food particles
◉ saprozoic.
Answer: Feed upon small, soluble food molecules
◉ Paramecium spp.
Answer: have hair-like appendages called cilia for locomotion.
protozoa
, ◉ Amoeba spp.
Answer: use lobe like pseudopodia to anchor the cell to a solid
surface and pull forward; protozoa locomotion
◉ Euglena spp.
Answer: use a whip-like structure called a flagellum to propel the
cell; protozoa locomotion
◉ Eukaryotic Supergroups.
Answer: This tree shows a proposed classification of the domain
Eukaryabased on evolutionary relationships. Currently, the domain
Eukaryais divided into six supergroups. Within each supergroupare
multiple kingdoms. Dotted lines indicate suggested evolutionary
relationships that remain under debate.
◉ eukaryote supergroups.
Answer:
◉ Amoebozoa.
Answer: Protozoans that use amoeboid movement
a)Actin microfilaments produce pseudopodia
b)Protoplasm flows into pseudopods
