unit 3 bio test Flashcards
LEARN CRYING SCREAMING THROWING UP
shoot system?
above soil structure
root system
under soil
mesophyll
layer of leaf with chloroplast
stomata
regulates 02 & C02 / tiny holes that allow oxygen and carbon dioxide to enter and exit plant
guard cell
opens and closes stomata
xylem
transports water and minerals
phloem
transports sap/ stuff thats not water ig
herbaceous
plant with soft flexible stems (flowers)
woody
plants without a soft stem (tree)
leaves > CUTICLE:
a waxy layer that covers the leaf
roots
anchor plant in ground/absorbs nutrients for plant
root hairs
small hairs on the root, covers more area for plant to get more nutrients
fibrous
plants that have several small branching out roots (flower)
taproot
plant that only have ONE big main root
vascular system
tissues transports nutrients and fluids through out the plant body
transpiration
vapor leaves plant via stomata
what happens when guard cells are open and closed
when open water leaves the plant and when closed water is trapped in the plant
4 groups of plants
mosses > non-vascular > moss
Ferns > seedless > evergreen tree
gymnosperms > cone bearing > many types of trees
angiosperms > flower bearing > sunflower
sexual production
two parent plants, seeds, pollen
asexual production
one parent parent plant, process of vegatitve propagation
which are male and which are female
stamen, pistil, anther, style, stima, filament, ovule, pollen
MALE >
stamen, anther, filament, pollen
FEMALE > pistil, stima, style, ovule
anther
pollen producing of the flower (M)
filament
slender stalk, supports anther (M)
pistil
female part of flower (F)
stigma
sticky tip of pistil - meant to catch pollen
style
tube shaped connection between stigma and ovule
ovule
structure that contains the female reproductive cells
peduncle
stalk of the flower
sepal
outer covering which protects the flower when in the Bud
fertilization
male gamete to female gamete to form a zygote
vegatitve propogation
leaves of pieces of stem/root are cut and used to grow new ones
4 main virus types
helical > helix
polyhedral > bunch of triangles
spherical > classic sphere
complex > ew brother ew type
how do spherical do their job
proteins on outside of cell help it attatch to and infect host cell
micro organism
microscopic organisms
disease
disorder of structure or function
pathogen
microbe that causes disease
are pathogens microbes or are microbes pathogens
pathogens are microbes
infectious disease caused by what
pathogen
non infectious disease caused by
caused by environmental genetic or lifestyle factors
types of pathogens
virus > non-cellular
bacteria > prokaryotic
parasitic > eukaryotic
fungi > eukaryotic
treatment for said pathogens
antivirals - virus
antibiotics - bacteria
antiparasitics - parasites
antifungal - fungi
