special bonus boi

Rhizobium
type of bacterium that can fix nitrogen

Planty boys

Vascular
Seeded

Angiosperm

Distinguish between monocots and dicots

know flower parts

Gymnosperm

know the dif conifer parts

Seedless

Lycopodiaphyta -phylum -Spike / Club mosses

Selaginella -spike moss -this is actually heterosporous

Lycopodium -club moss

Monilophyta -phylum

Horsetails -Photosynthesize on stem -Reduced Leaves -the sporangia is called strobili

Ferns -Sori: clusters of sporangia -Stipe: Stalk below blade -Frond: all da leaf -Blade: expanded leafy part of frond -Pinna: division of blade -Rhizome: underground stem -they got roots

Nonvascular
Bryophyta -phylum

Polytrichium

Marchantiophyta -phylum

Liverworts -reproduce asexually via gemmae cups -rhizoid roots

Main topic

Protists

Unikonta
Mycetozoa / slime molds

Dictydium -Reproductive structure of a slime mold

Amoebozoa -phylum -phagocytosis -pseudopodia

Amoeba -move using extensions called pseudopods

Archaeplastida
Rhodopyta -pigment : phycoerythrin
Chlorophyta

Caulerpa -Has fronds and rhizoides like brown algae

Pandorina -colonial green algae

Spirogyra -filamentous

Chlamydomonas -two flagella, stigma

SAR
Rhizaria -Thread-like pseudopodia
Alveolata -got sack-like alveoli under plasma membrane

Stentor -chainsaw cilia

Dinoflagellates -interlocking cellulose plates -have chloroplasts

Stramenopiles -straw-like hairs

Brown Algae -stipe: Stem -airbladders: provide buoyancy -holdfast: root-like structure -frond: leaf-like structure

Diatom -Cell wall made of Silicon Dioxide -unicellular Algae

Excavata
Giardia -Parasite; Causes disease (Giardiasis)
Trypanosoma -Parasitic, causes disease (sleeping sickness) -Moves using undulating membrane -
Euglena -Can be heterotrophic or autotrophic -Pellicle: unique cell surface, makes it flexible -Stigma: Colored eye spot -Flagella

Prokaryotes

Gram Staining Results
Gram Negative -Serratia marcescens
