Plant like protists

Plant-like Protists

Phytoplankton

All are photosynthetic

Sessile algae

Are classified according to their unique characteristics


Phytoplankton

Phytoplankton

  • We will study 2 plant-like protists:

  • Euglena (flagellate)

  • Spirogyra (sessile algae)


Euglena

Euglena

  • Euglena gracilis

  • Division Euglenophyta

  • Movement – use of flagellum

    • - can also move by changing it’s shape in a process called “euglenoid” movement


Euglena1

Euglena

  • Food – Photosynthetic

    • 6CO2 + 6H2O C6H12O6 + 6O2

    • Euglena can switch to being heterotrophic if they can’t find any light (now that’s cool!)


Euglena2

Euglena

  • Reproduction – Asexual binary fission

  • Special Structures

  • Flagellum – locomotion

  • Chloroplasts – site of photosynthesis

  • Eye spot – light sensitive pigment


Euglena3

Euglena


Spirogyra

Spirogyra

  • Spirogyra ternatum

  • Division Chlorophyta

  • Movement – sessile

  • Food – Photosynthesis

  • (You write the equation)


Spirogyra1

Spirogyra

  • Reproduction – filaments of spirogyra line up and connect with conjugation tubes.

  • All the contents of the donor cell pass through the tube into the recipient cell

  • The donor cell is now a dead, empty cell

  • Since the filamentous cells are considered haploid (n), the recipient cell is now considered a zygote (2n)


Conjugation continued

Conjugation continued

  • The zygote becomes protected by a Zygospore

  • Eventually the zygote divides by meiosis to produce more haploid cells


Spirogyra2

Spirogyra

  • Special structures

  • Conjugation tube

  • Spiraling chloroplast

  • Zygote

  • Zygospore


Spirogyra3

Spirogyra
