2. Rhizopoda Popularly known as “Amoebas”
All unicellular and move through pseupodia
Cytoskeleton with microtubules and microfilaments
Live in the soil, freshwater, and saltwater
Asexual reproduction
Amoeba
Pseudopodia

3. Radiolarians Heliozoans
Axopod
Pseudopodia
Type of Actinopod, which refers to organisms with an axopodia, a special type of pseudopodia
Axopodia mainly make up an internal skeleton
Radiolarians are marine actinopods with skeletons infused into one piece
When they die, their skeletons accumulate on the sea floor as ooze
Heliozoans
Heliozoa
Axopod
Type of Actinopod that lives in freshwater
Skeletons consists of chitinous un-fused plates with axopods radiating outward from the spherical cell
Phagotrophs

4. Foraminifera Structures-
Have porous shell covering them, that are multi-chambered and consist of organic sediment hardened with calcium carbonate
Also have strands of cytoplasm called reticulating pseudo pods that forms a dynamic net and allows them to swim
Usually 1 mm in size, but can be up to 20 cm

5. Foraminifera Calcareous Ooze-
General term for layers of muddy, calcium carbonate sediments on sea floor and is very basic
Made up of planktic and benthic fossils
Coccolithophorids and planktic foraminifera form the largest part of the ooze
Foraminiferal ooze, a type of calcareous ooze containing foraminifera covers 1/3 of the earth’s surface
Reveals past environmental conditions such as past oceanic characteristics, past geological land formations, and past climate conditions

6. Paramecium Structure – Conjugation –
Two types of nuclei, large polyploid macronucleus (controls everyday activities) and micronuclei (diploid/function in sexual reproduction)
Covered in thousands of cilia lined inside the oral groove
Contractile vacuole to regulate osmotic pressure
Conjugation –
Asexual process reproduces with binary fission
Micronucleus starts process and signals everything to divide
Sexual process reproduces with conjugation
Two individuals line up and replicate their macronuclei creating 4 through meiosis, but only keeping 1 for mitosis
They then swap one of their micronuclei
