Topic: Classification Aim: Explain the characteristics of some different protists. Do Now: List the 6 kingdoms that exist. HW: Textbook assignment about the different types of protists is due tomorrow!
Review: Identify the kingdom described. 1.Multi-cellular and autotrophic 2.Unicellular, eukaryotic, autotrophic or heterotrophic 3.Multi-cellular and heterotrophic 4.Multi-cellular, absorb digested food from the environment 5.Unicellular, prokaryotic, live in extreme environments 6.Multi-cellular, heterotrophic, ingest food 7.Unicellular, prokaryotic, most are beneficial, some are harmful
Pseudopods: extensions of cytoplasm – to ENGULF food –to move around
Phagocytosis: process in which pseudopods ENGULF food –Vacuole and lysosome fuse together to digest food
pseudopods food vacuole
Cyclosis: used for transport & locomotion
Contractile vacuole: contracts to release extra water Contractile vacuole pseudopods food vacuole
- Live in freshwater & too much water diffuses in
Let’s summarize… 1.What kind of nutrition is used by protists such as ameba and paramecia? 2.Explain how ameba and paramecia ingest food. 3.Once food is ingested, explain how it is digested. 4.How do ameba and paramecia maintain water balance?
Review: Ameba ingest large pieces of food by the process of (1.) Diffusion (2.) Osmosis (3.) Phagocytosis (4.) Respiration
Once food is ingested by a paramecium, the food is surrounded by a (1.) ribosome (2.) vacuole (3.) golgi body (4.) nuclear membrane
A paramecia uses ___ for movement and capturing food. (1.) pseudopods (2.) flagella (3.) teeth (4.) cilia
The process which moves cytoplasm around the protist is known as (1.) diffusion (2.) osmosis (3.) cyclosis (4.) locomotion
Some protists remove excess water with the help of (1.) lysosomes (2.) contractile vacuoles (3.) oral grooves (4.) food vacuoles
In paramecia, wastes are expelled through the (1.) oral groove (2.) anal pore (3.) lysosome (4.) contractile vacuole
