Protists are eukaryotic, one- or many-celled organisms that live in aquatic environments. They can be plant-like, animal-like, or fungus-like. Protists reproduce both sexually and asexually. Major groups of protists include algae, which use photosynthesis, protozoa which are single-celled animal-like protists, and ciliates which use cilia for movement. Fungi are many-celled organisms that feed on dead and decaying matter and reproduce via spores. Lichens are symbiotic organisms consisting of a fungus and algae or cyanobacteria.

1. Protists
- a protist is a one- or many- celled organism that
lives in wet surroundings.
- all protists have eukaryotic cells (cells with a
nucleus and other membrane-bound organelles)
- protists may be plant-like, animal-like, or
fungus-like
(Copy Table 1 on page 211)

3. - Some protists reproduce asexually, resulting in
genetically identical offspring
- Some protists reproduce sexually, and produce
genetically different offspring
- Scientists think that protists evolved from a one-celled
organism with a nucleus and other
structures.

4. • - Plantlike protists have cell walls and contain
chlorophyll

5. • - Animal-like protists are separated into groups
according to how they move

6. • - Funguslike protists have characteristics found in
both fungi and protists

7. • Algae are plantlike protists.
- algae contain chlorophyll and produce oxygen as a
result of photosynthesis
- There are many different types of algae. They
include diatoms, dinoflagellates, red or green algae
commonly called seaweed, and brown algae known
as kelp.

8. • - Dinoflagellates have two flagellum, long,
thin, whiplike structures used for movement.

9. • - Protozoans are one-celled, animal-like protists
- Protozoans can live in water, soil, and in living
or dead organisms

10. • - Protists called ciliates are covered in cilia, short,
thread-like structures that extend from the cell
membrane.
• - cilia help the organism
to move quickly in any direction.
• - a Paramecium is a ciliate
that has two nuclei
• - Paramecium are found in freshwater
environments and consume bacteria.

11. • - Pseudopods are extensions of cytoplasm used by
some protists to move through their environment.
• - the word “pseudopod” means “false foot”

14. • Fungi
- Fungi are organisms that grow in soil and have a
cell wall. Because they do not contain chlorophyll or
have the structures of plants, they cannot be
categorized as plants.
• - Most species of fungi are many-celled

16. • - Hyphae are the mass of threadlike tubes which
form the body of a fungus

17. • - Most fungi are saprophytes.
- A saprophyte is an organism that gets food by
absorbing dead or decaying tissues of other
organisms
- Some species of fungi are parasites, obtaining
their food directly from living things

19. • - Fungi can reproduce sexually or asexually. In either
case, fungi reproduce through spores
• - A spore is a waterproof reproductive cell that
can grow into a new organism.

20. • - Common fungi include mushrooms and yeast.
- yeasts can reproduce by budding, a form of
asexual reproduction in which a new organism
forms on the side of a parent organism.

21. Lichen
• - a lichen is an organism that is made up of
fungus and either a green algae or a
cyanobacterium.
- lichens are food sources for many animals.
- lichens are used to determine pollution levels in
an area
