Most protista are |
unicellular and microscopic |
|
most protista can be |
can be multicellular they can be colonies, several meters long, some of them are kelp, can be heterotrophs, autotrophs or parasites. |
|
Characteristics that are believed to be common to ancestor of all eukaryotes |
Cells with a nucleus surrounded by a nuclear envelope with nuclear pores.Mitochondria or some remnant of mitochondria Some form of cytoskeletonFlagella or ciliaChromosomes wrapped around some type of protein (histones)All do mitosisCan reproduce sexually at some pointThe ability to make a cell wall |
|
The theory of how eukaryotes evolved |
endosymbiosis- endosymbiotic theoryOne cell engulfs another, they both survive, and became dependant of each other. |
|
Evolutionist think that mitochondria came from |
aerobic(being able to make energy using oxygen) bacteria that were engulfed by another cell. |
|
Evolutionist think chloroplasts came from |
cyanobacteria that did photosynthesis from being engulfed |
|
Excavata |
Asymmetrical, they aren’t even Unicellular Feeding groove where they allow their food to come in |
|
Chromalveolata |
Really protected, a coat of armer Two flagella, move in opposite directions One of the main things that make up plankton |
|
Rhizaria |
Amoebasthreadlike pseudopodsPseudopods- move by cytoplasmic streaming< vocabForams- look like shells, unicellular, have pores in their shells with pseudopods that they can get food or move with |
|
Archaeplastida |
Algae(red or green) and land plants Red- looks red when it does photosynthesis, multicellular, no flagella. Green- common in wet places, volvox( lives as a colony, some individuals have special functions like reproducing), all move at the same time, some green algae can have a huge cell and thousands of nuclei |
