intro and excavata group

Question 1

What kind of cell are protists

Answer 1

Eukaryotes and are very diverse

Question 2

Clades of excavata

Answer 2

Diplomonads, euglenozoans, parabasilids

Question 3

The protists- excavata

Answer 3

Members in this clade have an “excavated” feeding groove on the side of the cell body

Question 4

Diplomonads

Answer 4

In excavata group

Has modified mitochondria called mitosomes

Lack e- transport (no O2) and live in anaerobic environments

Many are parasites
Multiple flagella and 2 nuclei

Question 5

Parabasilids

Answer 5

Modified mitochondria called hydrogenosomes

Release hydrogen as byproduct
Many are parasites

Question 6

euglenids (feeding, cell type, trait)

Answer 6

some autotrophic, some also heterotrophic (when no light), known as mixotrophy

unicellular freshwater organisms, no cell walls, membrane-bound nucleus

contractile vacuole (expands and contracts when pumping water), has 1-2 flagella that differ in structure from other organisms)
