protists
eukaryotes that are not members of the plant, fungi, or animal kingdoms
pseudopod
projection of cytoplasm
amoeboid movement
movement by changing shape
cilia
short, numerous hair-like structures supported by microtubules
flagellum
long and one/ two per cell, and moves in a wavelike motion
passive movement
many protists use air and water currents to move them
spores
reproductive cells
conjugation
a process in which 2 organisms exchange genetic material and increase of genetic diversity before going through asexual reproduction
alternation of generations
life cycle that alternates between a diploid and haploid phase
sporangium
spore capsule in which haploid spores are produced by meiosis
micronucleus
reserve copy" of genes
macronucleus
day-to-day activities
symbiotic relationships
relationship in which 2 organisms live closely together
mutalistic
both organisms benefit
parasitic
one organism benefits and the other is harmed
chitin
polymer of modified sugars
hyphae
thin filaments of which multicellular fungi are composed
cross walls
divide hyphae into "cells" but still have openings for cytoplasm and organelles to pass through
mycelium
composed of many hyphae tangled together in thick mass
fruiting body
reproductive structure of a fungus growing from mycelium
fairy rings
mushrooms growing in circles : one mycelium many fruiting bodies
fungi as decomposers
Fungi are efficient decomposers of organic material including cellulose and lignin
fungi as parasites
parasite fungi can cause serious plant and animal diseases by disrupting homeostasis
lichens
mutalistic relationship
mycorrhizae
relationship between fungi and plant
Two ways protists get their energy
photosynthetic, heterotrophic
Different ways protists consume
amoebas, ciliates, slime molds, and water molds
