Chapter 23 Flashcards
(27 cards)
Where in the food chain are protista?
They are primary producers and account for 50% of total carbon fixation
What a re plankton?
Diatoms or any other tiny organism that drift in the water
How have protista impacted human health?
Irish potato famine
Malaria
Sleeping sickness
The first animal on earth
Sponge/ Choanoflagellates
Choanocytes
The inner lining of sponge
Primary vs Secondary endosymbiosis theory
Primary absorbs a prokaryote while secondary absorbs another eukaryote
Primary endosymbiosis example
Mitochondria
Secondary endosymbiosis example
Red and green aglae
How do amoeboids move?
They use pseudopods and move their cell contents through them
How do flageolets move
They use flagella as a motor
How do collates move?
They uses cilia and crawl
How do heteroknots move?
They use a flagella (feather like) and point in the way they wanted to go
V
Alternate generations
Life cycle is based on polidy of the cell
gametophyte
Haploid —> sexual reproduction
Sprorphyte
Diploid —>asexual reproduction
Diatom reproduction
(Ask prof. Goff or read in text book)
Organisms that cause HAB
Cyanobacteria, Diatoms, Dinoflagellates
Causes of HABs
- P and N chemical waste
- Thermal pollution
- Low water levels
What is CFP
Ciguatera Shellfish poisoning caused by ciguatoxin causes cold to feel hot and hot to feel cold
What is ASP
Amnesiac Shellfish poisoning caused by Domoic acid causes life threatening brain shit
Carbon sinking
Organisms that consume more carbon from the atmosphere than it releases
Organic sediment vs Calcareous sediment
Organic sediment is caused by primary producers and carbon sinking while calcareous sediment is caused by the weathering of calcite rocks
Upwellings
Deeper water and carbon is brought up due to the thermal line being broken (hot water rises and cold water descends)
