hyphae
|
the tubular threads that make up filamentous
fungi (molds). |
|
mycelium
|
composed of hyphae, this filamentous mass
makes up a mold. |
|
saprophyte
|
an organism that decomposes organic remains
from dead animals; also known as a saprobe or saprotroph. |
|
autotroph
|
organism that uses inorganic carbon
(carbon dioxide / CO2) as its primary carbon source. |
|
heterotroph
|
organism that uses organic carbon compounds
(proteins, carbohydrates) as its primary carbon source. |
|
chemotroph
|
organism that uses chemical compounds as an
energy source. |
|
phototroph
|
organism that uses sunlight as an energy source
|
|
protozoan
|
Most exist as trophozoites (active, feeding stage),
while some can become cysts in harsh conditions. Most move by pseudopods, cilia, or flagella, while apicomplexans have no motility. |
|
algae
|
This group is diverse in color (green, red, brown),
while some have no color. The majority have cellulose in their cell walls, while a few have silica or gel‐like polysaccharides, agar or carrageenan. |
|
fungus
|
This group can be microscopic or macroscopic.
Multicellular organisms are made up of hyphae that intertwine to form a mycelium; hyphae walls contain chitin and can be either septate or non‐septate. |
|
Flagella, cilia, and pseudopods
|
Name the three types of locomotion structures
found in protozoans. |
|
Euglena is a photoautotroph like algae, however,
it lacks a cell well like protozoans. Instead, Euglena have a pellicle. |
What characteristics make it hard to classify
Euglena as a protozoan or algae? |
|
Fungi produce excretory enzymes that break
down the substrate and then absorb the resulting nutrients. |
How do fungi obtain their nutrients?
|
|
Yeast can reproduce through budding and fission.
|
How do yeasts reproduce?
