biology 1407 exam 3 questions with complete solutions
3 phylum of nonvascular plants Correct Answers -hepatophyta
-bryophyta
-anthocerophyta
absorptive heterotrophs Correct Answers secrete digestive
enzymes outside the body to break down large organic
molecules. smaller molecules absorbed through cell membrane
accessory fruit Correct Answers include more than just the
carpel and the ovaries
aggregated fruit Correct Answers from a single flower that has
more than one separate carpel that each grow into a cluster of
fruitlets on a single receptacle
all plants begin with primary growth at....... Correct Answers
apical meristems
angiosperm clades (4) Correct Answers basal angiosperm,
magnoliids, monocots, eudicots
anther Correct Answers terminal sac that produces pollen
antheridium Correct Answers male gametangium, multicellular
structure that produces sperm, haploid structure makes haploid
sperm
apical bud Correct Answers at the tip of the stem, most growth
concentrated here
,apical dominance Correct Answers ind=hibits growth of
axillary buds
apical meristem or primary growth Correct Answers at the tips
of roots and shoots, responsible for lengthening growth
arbuscular mycorrhizal Correct Answers extend branching
hyphae through root cell wall into invaginations of root cell
plasma membrane
archegonium Correct Answers female gametangium
-multicellular structure that produces eggs in non vascular land
plants, ferns, gymnosperms
-haploid eggs made by haploid structure
axillary buds Correct Answers form in the upper angle where
leaves attach to a stem, form lateral shoots
bark Correct Answers all tissues external to the vascular
cambium
basal angiosperm 3 lineages Correct Answers -lacks some of
xylem cells of other angiosperm
-water lilies
-star anise and relatives
basidium Correct Answers club shaped cell in which meiosis
occurs to generate haploid basidiospores
, carpel Correct Answers modified leaf of angiosperm that
contains one or more ovules
Characteristics all seed plants possess Correct Answers -
reduced, dependent gametophytes and dominant sporophytes
-heterospory
-ovules and eggs
-pollen and sperm
-secondary growth
chitin Correct Answers flexible nitrogen-containing
polysaccharide that forms the cell wall of poysaccharide wall f
fungus and the exoskeleton of athropods
coenocytic Correct Answers hyphae lack septa so they are one
mass of cytoplasm which contains hundreds or thousands of
nuclei
conidiophore Correct Answers specialized hypha that has a
budding or produce spores called conidia
cork cambium Correct Answers replaces epidermis with
thicker, tougher, wax-impregnated periderm
cortex Correct Answers ground tissue outside the vascular
bundles
cotyleons Correct Answers two seed leaves
Cuticle Correct Answers waxy coating on epidermis to provide
watertight covering for plant's cells
