botany practical 2 Flashcards
when does fermentation occur
when there is no oxygen after glycolysis
what does fermentation make
lactate, ethanol and CO2
green algae habitat and adaptation
aquatic habitat, sperm has a flagella to swim to egg in water
phases of a plant
sporophyte (2n) and gametophyte (n)
what phase does moss spend most of it’s life cycle in
gameophete (haploid) - reproduces for most of its life
what phase do monilophytes (ferns, horsetails) stay in for majority of their life
sporophyte - diploid
how do monilophytes reproduce (ferns)
releasing spores
what are gymnosperms
like pine trees
how do gymnosperms release sperm
Some have flagellated
sperm (ginkgos and cycads)
but others do not. Sperm
are moved in pollen via
wind or insect
gymnosperms are ___ dominant
sporophyte - (diploid) - they spend most of their life as trees
what are angiosperms
flowering plants
how do angiosperm move
Non-flagellated sperm -
pollen transported by
wind, insects
what phase do angiosperms mostly live in during their life
sporophyte (diploid)
two components of soil
organic
plant matter, living organisms
inorganic
sand, silt, clay, minerals
3 components of soil
sand (largest particle size, spreads worst)
silt
clay (smallest particle size - spreads farthest)
asexual reproduction
totipotent cells
propagating is used when
they want to keep the traits of a plant without reproducing the seed (that is hard)
ethylene
ripening agent
