move via many hair-like projections from the cell membrane called cilia (cilia also helps to sweep food in the oral groove)
Example would be Paramecium that commonly are found feeding on organisms in bacteria (its a monster because its a decomposer). However, they are actually super geniuses and possess the ability to learn infomation and communicate through radiation
contractile vacuole- absorb water by osmosis from the cytoplasm, and after the canals fill with water, the water is pumped into the vacuole. When the vacuole is full, it expels the water through a pore in the cytoplasm which can be opened and closed
gullet- like an esophagus push the food from the mouth down to the stomach.
oral groove- collects food until it is sweeped into the cell mouth
cilia are the grainy outside bits.
-diverse group that contains predators, photosynthesizers, and endosymbionts. Most live in marine ecosystems and swim with two long flagella. Essentially, they live like a fish with fins.
Those that are photosynthetic play a major role in marine ecosystems as primary
producers (bottom of the food chain)
can cause red tides when populations bloom
pellicle- protective layer of the function
cyst- sack-like fluid bag; can cause problems if it is filled with pus or other substances
dinocyst- functions include adverse conditions, bloom initiation and termination, dispersal in time, a seed bank for genetic diversity and dispersal in spac (trichocyst has an unknown function)
-immobile, single-celled parasite causes malaria- one of the most
common diseases in humans worldwide
- It spends some part of its life in female mosquitoes, which inject the protist into a human’s bloodstream when it bites. The protist then continues its develop inside the human red blood cell.
know nucleus, mitocondrion
denuse granules-secretaory organelles
micropore-function as cytostomes and the invaginations (infolding of one part in part of another organism, starts with gradulation) take in material by means of pinocytosis
apicoplast- essential to parasite survival
microenmes- smooth ER, site of detoxification of drugs and poison
- most common life forms that make up phytoplankton, the microscopic photosynthetic organisms that form a greenish layer on the surface of the ocean.
- form a critical first step in the food chain; they make food from sunlight, are eaten by bigger things, which are then eaten by bigger things
- make a hard cell wall of silica (called a frustule). Silica is sand or glass and is the most common mineral in earth’s crust.
-shells of dead diatoms are used for toothpaste
centric looks like a circle, pennate are pen shaped
-unique among the protists from today’s lab in that they are multicellular and can even form giants growing to over 45 m (150 ft). B
-better known as kelp, a type of seaweed
-form huge underwater forests that serve as homes to many famous sea creatures, like sea otters and sharks.
