Thallus = metabolizing
plant body composed of simple cells
Thallophytes= organisms
with a thallus; in this course
- Some Protista ---water molds
- Fungi
- Algae
The thallus of thallophyes
- plasmodiummultinucleate
mass of protoplasm with no cell wall
- single cell
- hyphae: filament,
about the size of one hair
- non-septate (coenocytic)
without cross walls
- septate: with cross
walls
- mycelium: mass of
interconnecting hyphae
- different means of obtaining carbohydrates than
in plasmodium; found in substrate
