Plant-like Protists
Nancy Tran & Priscila Gugol
BIO 241
- Kingdom: Protista
- Eukaryotic
microorganisms
Organisms include:
amoeba, red algae,
dinoflagellates,
diatoms, euglena, &
slime molds.
- Little tissue organization.
(includes: Animals, some algae/protists)
1. Zygote divides  develops into
multicellular diploid sporophyte.
2. Cells derived from sporophyte undergo
meiosis = gametes (n).
3. Gametes (n) will fertilize one another to
make new zygote (2n).
