Chapter 23 major lineages

Question 1

Archaeplastida

Answer 1

Alternate generations, Photosynthesis, Most algae

Question 2

Amoebozoa

Answer 2

Distribute nutrients and oxygen from the pseudopod movement

Question 3

Opisthokonta

Answer 3

Includes commons ancestor of sponges, have weird uses of flagella (for extra cellular movement or like a lasso)

Question 4

Rhizaria

Answer 4

Calcium bicarbonate structures on cell wall that contribute to carbon cycle, threadlike pseudopods, formanfiera

Question 5

Chromalveolata

Answer 5

secondary endosymbiosis, very important photosynthetic organisms diatoms and dinoflagellates

Question 6

Excavata

Answer 6

2 Flagella, Euglena, mixotrophs

Question 7

Diatoms

Answer 7

Notable things: weird life cycle,
Strcuture: silicon dioxide (glass)
Movement: hairy flagellum
Ecology: HABs, photosynthetic,

Question 8

Dinoflagellates

Answer 8

Notable things: Red tides, cellulose plates, bioluminescence
Strcuture: cellulose plates
Movement: flagella
Ecology: Photosynthetic (plankton)

Question 9

Formanfiera

Answer 9

Notable things: contributions to carbon cycle & Nitrogen cycle
Strcuture: calcium bicarbonate cell wall
Movement: pseudopods
Ecology: contribution to water cycle/organic sediment and also can help for denitrification

Question 10

Euglena

Answer 10

Notable things: eyespot
Strcuture: tough/flexible bands of protein attach to cyto skeleton
Movement: Has an eyespot that helps it move with 2 falgella
Ecology: Can photosynthesize, but can be mixotrophs
