- DNA loop
- mito. are double membrane bound
- ribosomes
- division by fission
- inherited cytoplasmically

proteobacteria
plastids are primary endosymbiosis from with bacteria?
cyanobacteria
What is psudopodia?
movement by shifting cytoplasm
-using a pseudopod
3 types of fertilization
- gametic cycle
- zygotic cycle
- sporic cycle
What uses the gametic cycle
animals
What uses the zygotic cycle
most fungi
What uses sporic cycle
plants
What is the gametic cycle?
The gamete (egg or sperm) is the only haploid cell produced
what is the zygotic cycle?
The zygote is the only diploid cell produced
