Kingdom Protista
Defined by exclusion. Eukaryotic. Mostly unicellular.
Algae
Plant like protist. Photosynthetic autotrophs. Possess chlorophyll a. Mostly aquatic with flagella. Mostly unicellular, colonial, filamentous.
Slime molds
Fungus like protists. Unicellular, absorptive heterotrophs.
Water molds
Fungus like protists. Types are oomycota and chytridiomycota.
Kingdom Fungi
Eukaryotic, absorptive heterotrophs. Cell wall made of chitin. excess sugar stored as glycogen. Mostly multicellular.
Mold
A fungi. Unicellular tangled masses of filaments.
Yeast
A fungi. Unicellular, colonial.
Hyphae
One filament in fungi
Mycelia
All filaments put together in a fungi.
Mycology
The study of fungi.
Septate hyphae
When the boundaries between cells in the hyphae are clearly visible.
Coenocytic hyphae
When the boundaries between cells in the hyphae are not visible.
Deuteromycota
Fungi that lack a sexual mode of reproduction. Not based on evolutionary evidence.
Lichens
A fungi that has a mutual relationship with algae or cyanobacteria. The fungus has a photosynthesizer inside it that gives it glucose.
Mycorrhizae
A fungi that has a mutual relationship with plant roots. Greatly increases root absorption.
Kingdom Plantae
Photosynthetic, eukaryotic, cell walls made of cellulose, chloropasts, multicelular, possess true tissue and organs, indeterminate growth, chlorophyll a and b and caratenoids.
Xylem
Inside plants. used for moving water.
Phloem
Inside plants. Used for moving food.
Bryophytes
Nonvascular (ie. mosses)
Ferns
Vascular and seedless
Monocot
Only in angiosperms. 1 seed leaf. Parallel vennation. Flower parts in 3x. Fibrous root system.
Dicot
Only in angiosperms. 2 seed leaves. Netlike vennation.Flower parts in 4-5x. Taproot.
Gametophyte
Haploid phase of plant cells' lives.
Sporophyte
Diploid phase of plant cells' lives.
Stigma
Place where pollen enters in an angiosperm.
Carpel
Female part of a flower
Style
Passageway in female part of flower where pollen travels through.
Stamen
Male part of a flower.
Anther
Part of flower that holds pollen
Filament
Holds up the anther
Ovary
Part of the flower that holds the seed.
Meristems
Regions of active mitosis in plants
Apical meristems
Meristems that contribute to growth at the tip of roots and tops of shoots.
Lateral Meristems
Meristems that contribute to secondary growth (growing outwards) in conifers.
Auxins
Promote cell elongation. Allow plants to move towards or away from stimulus.
Tropisms
Movements toward or away from stimulus.
Phototropism
Growth response to light.
