Download 3.04 and 3.05 Protists and Fungus Alternate Portfolio

Part 1: Protist Notes
•
–
Belongs to the domain Eukarya
•
–
Have similarities to other kingdoms, but all:
•
-
Have a necleus (eukaryotes)
•
-
Do not have specialized cells.
•
–
Can live in colonies (seaweed, kelp) though most are unicellular.
•
–
Prefer aquatic environments
•
–
Plant-like, animal-like, fungus-like
Plant-like Protist
•
•
•
•
Autotrophs - photosynthesis
Kelp, seaweed
Fungus-like Protist
•
•
•
•
Heterotrophs- decomposers
Molds, mildews
Animal-like Protist
•
•
•
•
•
•
•
•
Heterotrophs- most are parasites
Eat by endocytosis (using pseudopods)
Mobile- flagella, cilia, pseudopods
Amoeba, paramecium
Decide whether each is a bacteria, protist, or virus. (1 point each)
Bacteria, Protist, or Virus
Part 2: Fungus Notes
Fungus Characteristics:
-Eukaryotes
-Cell walls made of chitin
Traits
Prokaryotic, lives harmlessly in your gut.
Eukaryotic, base of the marine food web.
No nucleus, no cell membrane, prevented with
vaccines
No nucleus, flagella, killed by antibiotics.
Nucleus and flagella, causes disease.
-Heterotrophs and usually decomposers
-Reproduce Sexually and Asexually
Examples:
Mushrooms, Yeast, Thread-like Fungi, Ich (Fish disease), Athlete’s Foot, Ringworm
Anatomy:
•
Rhizoids – kind of like roots, but not.
•
Mycelium- formed by filaments called hyphae. Function in eating and
reproduction. 2 for 1!
•
Sporangiophores- release haploid spores. The "gills" of a mushroom are an
example.
•
Stolon – also made of hyphae, but above the ground. Can connect with other
fungus stolon to form a gametangia, which leads to sexual reproduction of sorts.

Complete the following fungus and protist activity using the link below.

Tip- Be sure to click all of the buttons before trying to classify it.
Fill in the chart as you complete the activity for 5 different organisms. The “Classification
Group” column should list one of the following: Animal-like protist, Plant-like protist, Fungus-like
protist, or Fungus. (5 points)

Answer these Journal Questions based on the activity, chart, and the notes from the LL.
1. Different types of protists move in different ways. Describe how one of the protists you
observed moves. (1 point)
2. Why are so many other living things dependent on plantlike protists? (2 points)
3. Which organisms could not move? Why? (2 point)
4. Which of the protists you observed had both plantlike and animal-like characteristics?
Explain what those characteristics were. (2 points)
5. Explain why algae are plant-like. (2 points)
6. Locomotion is generally a characteristic of animals. However, some plantlike protists move
about by means of a flagella. What is the adaptive advantage of a photosynthetic aquatic
organism that is able to move from place to place? (Hint: Remember that photosynthesis
requires light.) (2 points)
7. How do the fungi you identified obtain food? (Checkout the “reference” button to help answer
this.) (1 point)
8. How are fungi important to the environment? (2 points)
