Angiosperm

Distinguish between monocots and dicots

know flower parts

Lycopodiaphyta -phylum -Spike / Club mosses

Selaginella -spike moss -this is actually heterosporous

Lycopodium -club moss

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

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 -
